Comparing individual and community-level characteristics of people with ground beef-associated salmonellosis and other ground beef eaters: a case-control analysis
Salah Z , Canning M , Rickless D , Devine C , Buckman R , Payne DC , Marshall KE . J Food Prot 2024 100303 Salmonella is estimated to be the leading bacterial cause of U.S. domestically-acquired foodborne illness. Large outbreaks of Salmonella attributed to ground beef have been reported in recent years. The demographic and sociodemographic characteristics of infected individuals linked to these outbreaks are poorly understood. We employed a retrospective case-control design; case-patients were people with laboratory-confirmed Salmonella infections linked to ground beef-associated outbreaks between 2012-2019, and controls were respondents to the 2018-2019 FoodNet Population Survey who reported eating ground beef and denied recent gastrointestinal illness. We used county-level CDC/ATSDR Social Vulnerability Index (SVI) to compare case-patient and controls. Case-patient status was regressed on county-level social vulnerability and individual-level demographic characteristics. We identified 376 case-patients and 1,321 controls in the FoodNet sites. Being a case-patient was associated with increased overall county-level social vulnerability (OR: 1.21 [95% CI: 1.07-1.36]) and socioeconomic vulnerability (OR: 1.24 [1.05-1.47]) when adjusted for individual-level demographics. Case-patient status was not strongly associated with the other SVI themes of household composition and disability, minority status and language, and housing type and transportation. Data on individual-level factors such as income, poverty, unemployment, and education could facilitate further analyses to understand this relationship. |
Examining age and food irradiation knowledge as influential factors on the purchase of irradiated foods: United States, August 2022
Crawford TN , Ablan M , Canning M , Marshall KE , Robyn M . Food Prot Trends 2024 44 (3) 189-194 Foodborne illness affects approximately 48 million Americans annually. Food irradiation is a safe and effective way to kill bacteria and extend a product’s shelf life. However, challenges to wider implementation of this technology include consumer hesitancy stemming from misconceptions about safety and lack of knowledge of irradiation’s benefits. Research has shown that consumers are more willing to accept irradiation if informed about its safety. Because of increases in multistate foodborne outbreaks and consumers’ growing concern about and expectation of food safety, it is an opportune time to reconsider irradiation as a food safety tool. Consumer attitudes toward food safety differ by demographic characteristics; however, research on the association of demographic factors with attitudes on food irradiation are limited. Data collected from a survey (n = 1,009) conducted in August 2022 were analyzed to describe the relationship between age and food irradiation knowledge as influential factors to purchase irradiated foods. More than half (56%) of respondents reported that learning more about irradiation would likely influence purchasing decisions, and older adults were more knowledgeable about food irradiation. These findings suggest that age could be an important factor to consider when tailoring messaging as a prevention strategy around the benefits of food irradiation. © 2024, International Association for Food Protection.

Effect of ground beef irradiation on annual nontyphoidal Salmonella and Escherichia coli O157 burden and direct healthcare costs in the United States: A simulation study
Khan MA , Collier SA , Ablan M , Canning M , Robyn M , Marshall KE . J Food Prot 2024 100231 Over 20% of E. coli O157 illnesses and over 5% of Salmonella illnesses are estimated to be attributable to beef consumption in the United States. Irradiating ground beef is one possible method to reduce disease burden. We simulated the effect of ground beef irradiation on illnesses, hospitalizations, deaths, and direct healthcare costs from ground beef-associated E. coli O157 and Salmonella illnesses in the United States. To estimate the fraction of illnesses, hospitalizations, deaths, and direct healthcare costs preventable by ground beef irradiation, we multiplied the disease burden attributable to ground beef; the estimated percentage of ground beef sold that is not currently irradiated; the percentage of unirradiated ground beef that would be irradiated; and the percentage reduction in risk of illness after irradiation. We multiplied this fraction by estimates of burden and direct healthcare costs to calculate the numbers or amounts averted. Model inputs were obtained from the literature and expert opinion. We used Monte Carlo simulation to incorporate uncertainty in inputs into model estimates. Simulation outcomes were summarized with means and 95% uncertainty intervals (UI). Irradiating 50% of the currently unirradiated ground beef supply would avert 3,285 (95% UI: 624-9,977) E. coli O157 illnesses, 135 (95% UI: 24-397) hospitalizations, 197 (95% UI: 34-631) hemolytic uremic syndrome cases, 2 (95% UI: 0-16) deaths, and $2,972,656 (95% UI: $254,708-$14,496,916) in direct healthcare costs annually. For Salmonella, irradiation would avert 20,308 (95% UI: 9,858-38,903) illnesses, 400 (95% UI: 158-834) hospitalizations, 6 (95% UI: 0-18) deaths, and $7,318,632 (95% UI: $1,436,141-$26,439,493) in direct healthcare costs. Increasing ground beef irradiation could reduce E. coli O157 and Salmonella burden in the United States. Additional studies should assess whether targeted irradiation of higher-risk ground beef products could prevent similar numbers of illnesses with less total product irradiated. |
Salmonella Outbreaks Linked to Beef, United States, 2012-2019.
Canning M , Birhane MG , Dewey-Mattia D , Lawinger H , Cote A , Gieraltowski L , Schwensohn C , Tagg KA , Francois Watkins LK , Park Robyn M , Marshall KE . J Food Prot 2023 86 (5) 100071 The Centers for Disease Control and Prevention (CDC) has identified nontyphoidal Salmonella as one of the top five pathogens contributing to foodborne illnesses in the United States. Beef continues to be a common source of Salmonella outbreaks, despite the implementation of interventions at slaughter and processing facilities to reduce contamination of beef. We described Salmonella outbreaks linked to beef in the United States during 2012-2019, examined trends, and identified potential targets for intervention and prevention strategies. We queried CDC's Foodborne Disease Outbreak Surveillance System (FDOSS) for all foodborne nontyphoidal Salmonella outbreaks linked to beef as the single contaminated ingredient or implicated food, with the date of first illness onset from 2012 to 2019. Information on antimicrobial resistance (AR) for outbreak-related isolates was obtained from CDC's National Antimicrobial Resistance Monitoring System (NARMS). We calculated the number of outbreaks, outbreak-related illnesses, hospitalizations, and deaths overall, by beef processing category and Salmonella serotype. During 2012-2019, 27 Salmonella outbreaks were linked to beef consumption, resulting in 1103 illnesses, 254 hospitalizations, and two deaths. The most common category of beef implicated was nonintact raw, ground beef (12 outbreaks, 44%), followed by intact raw (six outbreaks, 22%). Ground beef was responsible for the most illnesses (800, 73%), both of the reported deaths, and was the source of the largest outbreak. AR data were available for 717 isolates from 25 (93%) outbreaks. Nine (36%) of these outbreaks had isolates resistant to one or more of the antibiotics tested by NARMS, of which eight (89%) contained multidrug-resistant isolates. Several outbreaks reported highlight challenges faced during investigations, areas where further research may be warranted, and opportunities to prevent future outbreaks along the farm-to-fork continuum. |
Demographic and clinical characteristics of mpox in persons who had previously received 1 dose of JYNNEOS vaccine and in unvaccinated persons - 29 U.S. Jurisdictions, May 22-September 3, 2022
Farrar JL , Lewis NM , Houck K , Canning M , Fothergill A , Payne AB , Cohen AL , Vance J , Brassil B , Youngkin E , Glenn B , Mangla A , Kupferman N , Saunders K , Meza C , Nims D , Soliva S , Blouse B , Henderson T , Banerjee E , White B , Birn R , Stadelman AM , Abrego M , McLafferty M , Eberhart MG , Pietrowski M , DeLen SM , Creegan E , Diedhiou A , Wiedeman C , Murray-Thompson J , McCarty E , Marcinkevage J , Kocharian A , Torrone EA , Ray LC , Payne DC . MMWR Morb Mortal Wkly Rep 2022 71 (5152) 1610-1615 As of November 14, 2022, monkeypox (mpox) cases had been reported from more than 110 countries, including 29,133 cases in the United States.* Among U.S. cases to date, 95% have occurred among males (1). After the first confirmed U.S. mpox case on May 17, 2022, limited supplies of JYNNEOS vaccine (Modified Vaccinia Ankara vaccine, Bavarian Nordic) were made available to jurisdictions for persons exposed to mpox. JYNNEOS vaccine was approved by the Food and Drug Administration (FDA) in 2019 as a 2-dose series (0.5 mL per dose, administered subcutaneously) to prevent smallpox and mpox disease.() On August 9, 2022, FDA issued an emergency use authorization to allow administration of JYNNEOS vaccine by intradermal injection (0.1 mL per dose) (2). A previous report on U.S. mpox cases during July 31-September 3, 2022, suggested that 1 dose of vaccine offers some protection against mpox (3). This report describes demographic and clinical characteristics of cases occurring 14 days after receipt of 1 dose of JYNNEOS vaccine and compares them with characteristics of cases among unvaccinated persons with mpox and with the vaccine-eligible vaccinated population in participating jurisdictions. During May 22-September 3, 2022, among 14,504 mpox cases reported from 29 participating U.S. jurisdictions,() 6,605 (45.5%) had available vaccination information and were included in the analysis. Among included cases, 276 (4.2%) were among persons who had received 1 dose of vaccine 14 days before illness onset. Mpox cases that occurred in these vaccinated persons were associated with lower percentage of hospitalization (2.1% versus 7.5%), fever, headache, malaise, myalgia, and chills, compared with cases in unvaccinated persons. Although 1 dose of JYNNEOS vaccine offers some protection from disease, mpox infection can occur after receipt of 1 dose, and the duration of protection conferred by 1 dose is unknown. Providers and public health officials should therefore encourage persons at risk for acquiring mpox to complete the 2-dose vaccination series and provide guidance and education regarding nonvaccine-related prevention strategies (4). |
Reduced risk for Mpox after receipt of 1 or 2 doses of JYNNEOS vaccine compared with risk among unvaccinated persons - 43 U.S. Jurisdictions, July 31-October 1, 2022
Payne AB , Ray LC , Cole MM , Canning M , Houck K , Shah HJ , Farrar JL , Lewis NM , Fothergill A , White EB , Feldstein LR , Roper LE , Lee F , Kriss JL , Sims E , Spicknall IH , Nakazawa Y , Gundlapalli AV , Shimabukuro T , Cohen AL , Honein MA , Mermin J , Payne DC . MMWR Morb Mortal Wkly Rep 2022 71 (49) 1560-1564 As of October 28, 2022, a total of 28,244* monkeypox (mpox) cases have been reported in the United States during an outbreak that has disproportionately affected gay, bisexual, and other men who have sex with men (MSM) (1). JYNNEOS vaccine (Modified Vaccinia Ankara vaccine, Bavarian Nordic), administered subcutaneously as a 2-dose (0.5 mL per dose) series (with doses administered 4 weeks apart), was approved by the Food and Drug Administration (FDA) in 2019 to prevent smallpox and mpox disease (2); an FDA Emergency Use Authorization issued on August 9, 2022, authorized intradermal administration of 0.1 mL per dose, increasing the number of persons who could be vaccinated with the available vaccine supply(†) (3). A previous comparison of mpox incidence during July 31-September 3, 2022, among unvaccinated, but vaccine-eligible men aged 18-49 years and those who had received ≥1 JYNNEOS vaccine dose in 32 U.S. jurisdictions, found that incidence among unvaccinated persons was 14 times that among vaccinated persons (95% CI = 5.0-41.0) (4). During September 4-October 1, 2022, a total of 205,504 persons received JYNNEOS vaccine dose 2 in the United States.(§) To further examine mpox incidence among persons who were unvaccinated and those who had received either 1 or 2 JYNNEOS doses, investigators analyzed data on 9,544 reported mpox cases among men(¶) aged 18-49 years during July 31-October 1, 2022, from 43 U.S. jurisdictions,** by vaccination status. During this study period, mpox incidence (cases per 100,000 population at risk) among unvaccinated persons was 7.4 (95% CI = 6.0-9.1) times that among persons who received only 1 dose of JYNNEOS vaccine ≥14 days earlier and 9.6 (95% CI = 6.9-13.2) times that among persons who received dose 2 ≥14 days earlier. The observed distribution of subcutaneous and intradermal routes of administration of dose 1 among vaccinated persons with mpox was not different from the expected distribution. This report provides additional data suggesting JYNNEOS vaccine provides protection against mpox, irrespective of whether the vaccine is administered intradermally or subcutaneously. The degree and durability of such protection remains unclear. Persons eligible for mpox vaccination should receive the complete 2-dose series to optimize strength of protection(††) (5). |
Appliances used by consumers to prepare frozen stuffed chicken products - United States, May-July 2022
Marshall KE , Canning M , Ablan M , Crawford TN , Robyn M . MMWR Morb Mortal Wkly Rep 2022 71 (48) 1511-1516 Frozen stuffed breaded raw chicken products have repeatedly been implicated in Salmonella outbreaks (1). These products are partially cooked to set the breading, often making them appear cooked (2). Despite their appearance, these products need to be cooked to an internal temperature of 165F (74C) to ensure that they are safe to eat. Producers began implementing labeling changes in 2006 to more clearly identify these products as raw; many warn against using microwave ovens (microwaves) to prepare them and provide validated cooking instructions solely for conventional ovens (ovens) (3,4). However, outbreaks continued to occur after implementation of these labeling changes (4). To describe the demographic characteristics of persons who prepare frozen stuffed chicken products and which appliances they use to prepare them, data from a May-July 2022 representative panel survey were analyzed. Although most (82.7%) respondents used an oven as one of their cooking methods, more than one half (54.0%) of respondents also used another appliance, including 29.0% who used a microwave. Oven use was lower among respondents with household income <$25,000 (68.9%), and who lived in mobile homes or other portable types of homes (66.5%). Among respondents who reported using microwaves to cook these products, 8% reported using a microwave with 750 W of power, which might be insufficient to thoroughly cook such products (1,5,6). Economic and other factors might influence some groups' access to recommended cooking appliances. Companies could consider implementing additional interventions that rely less on labeling and consumer preparation practices and focus on controlling or reducing levels of Salmonella in these products, such as selling them fully cooked, or monitoring and testing Salmonella levels, to ensure safety. These findings highlight challenges consumers might face in preparing frozen stuffed chicken products safely and can guide strategies for regulatory authorities and industry to prevent outbreaks and illnesses associated with them. |
Incidence of monkeypox among unvaccinated persons compared with persons receiving 1 JYNNEOS vaccine vose - 32 U.S. jurisdictions, July 31-September 3, 2022
Payne AB , Ray LC , Kugeler KJ , Fothergill A , White EB , Canning M , Farrar JL , Feldstein LR , Gundlapalli AV , Houck K , Kriss JL , Lewis NM , Sims E , Smith DK , Spicknall IH , Nakazawa Y , Damon IK , Cohn AC , Payne DC . MMWR Morb Mortal Wkly Rep 2022 71 (40) 1278-1282 Human monkeypox is caused by Monkeypox virus (MPXV), an Orthopoxvirus, previously rare in the United States (1). The first U.S. case of monkeypox during the current outbreak was identified on May 17, 2022 (2). As of September 28, 2022, a total of 25,341 monkeypox cases have been reported in the United States.* The outbreak has disproportionately affected gay, bisexual, and other men who have sex with men (MSM) (3). JYNNEOS vaccine (Modified Vaccinia Ankara vaccine, Bavarian Nordic), administered subcutaneously as a 2-dose (0.5 mL per dose) series with doses administered 4 weeks apart, was approved by the Food and Drug Administration (FDA) in 2019 to prevent smallpox and monkeypox infection (4). U.S. distribution of JYNNEOS vaccine as postexposure prophylaxis (PEP) for persons with known exposures to MPXV began in May 2022. A U.S. national vaccination strategy(†) for expanded PEP, announced on June 28, 2022, recommended subcutaneous vaccination of persons with known or presumed exposure to MPXV, broadening vaccination eligibility. FDA emergency use authorization (EUA) of intradermal administration of 0.1 mL of JYNNEOS on August 9, 2022, increased vaccine supply (5). As of September 28, 2022, most vaccine has been administered as PEP or expanded PEP. Because of the limited amount of time that has elapsed since administration of initial vaccine doses, as of September 28, 2022, relatively few persons in the current outbreak have completed the recommended 2-dose series.(§) To examine the incidence of monkeypox among persons who were unvaccinated and those who had received ≥1 JYNNEOS vaccine dose, 5,402 reported monkeypox cases occurring among males(¶) aged 18-49 years during July 31-September 3, 2022, were analyzed by vaccination status across 32 U.S. jurisdictions.** Average monkeypox incidence (cases per 100,000) among unvaccinated persons was 14.3 (95% CI = 5.0-41.0) times that among persons who received 1 dose of JYNNEOS vaccine ≥14 days earlier. Monitoring monkeypox incidence by vaccination status in timely surveillance data might provide early indications of vaccine-related protection that can be confirmed through other well-controlled vaccine effectiveness studies. This early finding suggests that a single dose of JYNNEOS vaccine provides some protection against monkeypox infection. The degree and durability of such protection is unknown, and it is recommended that people who are eligible for monkeypox vaccination receive the complete 2-dose series. |
Effect of distance to health facilities and access to contraceptive services among urban Turkish women
Sato R , Rohr J , Huber S , Esmer Y , Okçuoğlu BA , Karadon D , Shah I , Canning D . Eur J Contracept Reprod Health Care 2021 26 (5) 1-9 OBJECTIVE: Worldwide unmet need for contraception remains high at 21.6%. As access to health facilities is one of the potential barriers to contraceptive uptake, the aim of our study was to evaluate the effect of distance to a health facility, according to its service availability, on contraceptive uptake among married Turkish women. METHODS: To calculate respondents' distance to a health facility, we used data from a household survey conducted among married women, as well as data from a health facility survey conducted among the facilities that were visited for contraceptive services by the respondents. The data were collected from the Istanbul area of Turkey under the Willows Impact Evaluation project in 2018. Health facilities were categorised according to contraceptive availability and the accurate distance from respondents' homes to each type of health facility was calculated. Logistic regression was used to estimate the effect of distance to each type of health facility on uptake of each type of contraception. RESULTS: The prevalence of overall contraceptive use among urban Turkish women was 71.9%. The most common method was withdrawal (32.5%), followed by the intrauterine device (IUD) (14.9%) and male condoms (12.4%). Distance to a health facility that did not provide long-acting contraception was not associated with any type of contraceptive use. On the other hand, distance to a health facility that provided long-acting contraception was negatively associated with the use of long-acting methods such as the IUD but was positively associated with the use of short-acting contraception such as condoms. CONCLUSION: The effect of distance to a health facility on contraceptive use significantly differed according to contraceptive availability at the facility. Further distance to a health facility that provided long-acting contraception decreased the use of long-acting contraception but had a substitute effect on the use of short-acting contraception. We conclude that when women face an accessibility barrier to the provision of long-acting contraception, they modify their behaviour by shifting from long- to short-acting contraception, which is less effective. |
Injury and illness among onshore workers in Alaska's seafood processing industry: Analysis of workers' compensation claims, 2014-2015
Syron LN , Lucas DL , Bovbjerg VE , Kincl LD . Am J Ind Med 2019 62 (3) 253-264 BACKGROUND: Alaska's onshore seafood processing industry is economically vital and hazardous. METHODS: Accepted Alaska workers' compensation claims data from 2014 to 2015 were manually reviewed and coded with the Occupational Injury and Illness Classification System and associated work activity. Workforce data were utilized to calculate rates. RESULTS: 2,889 claims of nonfatal injuries/illnesses were accepted for compensation. The average annual claim rate was 63 per 1000 workers. This was significantly higher than Alaska's all-industry rate of 44 claims per 1000 workers (RR = 1.42, 95%CI = 1.37-1.48). The most frequently occurring injuries/illnesses, were by nature, sprains/strains/tears (993, 36%); by body part, upper limbs (1212, 43%); and by event, contact with objects/equipment (1020, 37%) and overexertion/bodily reaction (933, 34%). Incidents associated with seafood processing/canning/freezing (n = 818) frequently involved: repetitive motion; overexertion while handling pans, fish, and buckets; and contact with fish, pans, and machinery. CONCLUSIONS: Ergonomic and safety solutions should be implemented to prevent musculoskeletal injuries/illnesses. |
Regional variations in home canning practices and the risk of foodborne botulism in the Republic of Georgia, 2003
Tarkhashvili N , Chokheli M , Chubinidze M , Abazashvili N , Chakvetadze N , Imnadze P , Kretsinger K , Varma J , Sobel J . J Food Prot 2015 78 (4) 746-50 Foodborne botulism is a severe, paralytic illness caused by ingestion of preformed neurotoxins produced by Clostridium botulinum. In 2003, we conducted a population-based household survey of home canning practices to explore marked regional variations in botulism incidence in the Republic of Georgia (ROG). We designed a cluster sampling scheme and subdivided each of the 10 regions of the ROG into a variable number of strata. Households were selected from each stratum using a two-step cluster sampling methodology. We administered a questionnaire about home canning practices to household members responsible for food preparation. Using multivariate logistic regression analysis, we modeled high (eastern ROG) against low (western ROG) incidence areas. Overall, we surveyed 2,742 households nationwide. Home canning with a capping device hermetically sealing the lid covering the jar was practiced by 1,909 households (65.9%; 95% confidence interval [CI]: 59.8 to 72.1%). Canning was more prevalent in regions of low botulism incidence (34 versus 32%; P < 0.01). When compared with low-botulism areas, the following practices were associated with an increased risk in high-botulism areas: ≥6 months between canning vegetables and consuming them (adjusted odds ratio [aOR] = 2.1; 95% CI: 1.3 to 3.5) and adding any of the following ingredients to the jar at time of preparation: >1 tablespoon of salt per liter (aOR = 5.1; 95% CI: 1.2 to 22.6); vinegar (aOR = 2.2; 95% CI: 1.3 to 3.7), and greens (aOR = 5.6; 95% CI: 1.7 to 18.2). The following practices were associated with a decreased risk in high-botulism areas: >57 jars canned per household annually (aOR = 0.5; 95% CI: 0.3 to 0.9), covering or immersing vegetables in boiling water before placing them into the jar (aOR = 0.3 95% CI: 0.2 to 0.6), covering or immersing vegetables in boiling water after placing them into the jar (aOR = 0.4; 95% CI: 0.2 to 0.9), or adding garlic (aOR = 0.2; 95% CI: 0.1 to 0.5) or aspirin (aOR = 0.1; 95% CI: 0.1 to 0.2) to the jar at the time of preparation. |
Breast cancer risk in relation to occupations with exposure to carcinogens and endocrine disruptors: a Canadian case-control study
Brophy JT , Keith MM , Watterson A , Park R , Gilbertson M , Maticka-Tyndale E , Beck M , Abu-Zahra H , Schneider K , Reinhartz A , Dematteo R , Luginaah I . Environ Health 2012 11 87 BACKGROUND: Endocrine disrupting chemicals and carcinogens, some of which may not yet have been classified as such, are present in many occupational environments and could increase breast cancer risk. Prior research has identified associations with breast cancer and work in agricultural and industrial settings. The purpose of this study was to further characterize possible links between breast cancer risk and occupation, particularly in farming and manufacturing, as well as to examine the impacts of early agricultural exposures, and exposure effects that are specific to the endocrine receptor status of tumours. METHODS: 1005 breast cancer cases referred by a regional cancer center and 1146 randomly-selected community controls provided detailed data including occupational and reproductive histories. All reported jobs were industry- and occupation-coded for the construction of cumulative exposure metrics representing likely exposure to carcinogens and endocrine disruptors. In a frequency-matched case-control design, exposure effects were estimated using conditional logistic regression. RESULTS: Across all sectors, women in jobs with potentially high exposures to carcinogens and endocrine disruptors had elevated breast cancer risk (OR = 1.42; 95% CI, 1.18-1.73, for 10 years exposure duration). Specific sectors with elevated risk included: agriculture (OR = 1.36; 95% CI, 1.01-1.82); bars-gambling (OR = 2.28; 95% CI, 0.94-5.53); automotive plastics manufacturing (OR = 2.68; 95% CI, 1.47-4.88), food canning (OR = 2.35; 95% CI, 1.00-5.53), and metalworking (OR = 1.73; 95% CI, 1.02-2.92). Estrogen receptor status of tumors with elevated risk differed by occupational grouping. Premenopausal breast cancer risk was highest for automotive plastics (OR = 4.76; 95% CI, 1.58-14.4) and food canning (OR = 5.70; 95% CI, 1.03-31.5). CONCLUSIONS: These observations support hypotheses linking breast cancer risk and exposures likely to include carcinogens and endocrine disruptors, and demonstrate the value of detailed work histories in environmental and occupational epidemiology. |
National outbreak of type A foodborne botulism associated with a widely distributed commercially canned hot dog chili sauce
Juliao PC , Maslanka S , Dykes J , Gaul L , Bagdure S , Granzow-Kibiger L , Salehi E , Zink D , Neligan RP , Barton-Behravesh C , Luquez C , Biggerstaff M , Lynch M , Olson C , Williams I , Barzilay EJ . Clin Infect Dis 2012 56 (3) 376-82 BACKGROUND: On July 7 and 11, 2007, respectively, health officials in Texas and Indiana reported 4 possible cases of type A foodborne botulism to the US Centers for Disease Control and Prevention. Foodborne botulism is a rare and sometimes fatal illness caused by consuming foods containing botulinum neurotoxin. METHODS: Investigators reviewed patients' medical charts and food histories. Clinical specimens and food samples were tested for botulinum toxin and neurotoxin-producing Clostridium spp. Investigators conducted inspections of the cannery that produced the implicated product. RESULTS: Eight confirmed outbreak associated cases were identified from Indiana (2), Texas (3), and Ohio (3). Botulinum toxin type A was identified in leftover chili sauce consumed by the Indiana patients and one of the Ohio patients. Cannery inspectors found violations of federal canned-food regulations that could have led to survival of C. botulinum spores during sterilization. The company recalled 39 million cans of chili. Following the outbreak, the US Food and Drug Administration inspected other canneries with similar canning systems and issued warnings to the industry about the danger of C. botulinum and the importance of compliance with canned food manufacturing regulations. CONCLUSION: Commercially produced hot dog chili sauce caused these cases of type A botulism. This is the first US foodborne botulism outbreak involving a commercial cannery in more than 30 years. Sharing of epidemiologic and laboratory findings allowed for the rapid identification of implicated food items and swift removal of potentially deadly products from the market by US food regulatory authorities. |
Three outbreaks of foodborne botulism caused by unsafe home canning of vegetables - Ohio and Washington, 2008 and 2009
Date K , Fagan R , Crossland S , Maceachern D , Pyper B , Bokanyi R , Houze Y , Andress E , Tauxe R . J Food Prot 2011 74 (12) 2090-6 Foodborne botulism is a potentially fatal paralytic illness caused by ingestion of neurotoxin produced by the spore-forming bacterium Clostridium botulinum. Historically, home-canned vegetables have been the most common cause of botulism outbreaks in the United States. During 2008 and 2009, the Centers for Disease Control and Prevention (CDC) and state and local health departments in Ohio and Washington State investigated three outbreaks caused by unsafe home canning of vegetables. We analyzed CDC surveillance data for background on food vehicles that caused botulism outbreaks from 1999 to 2008. For the three outbreaks described, patients and their family members were interviewed and foods were collected. Laboratory testing of clinical and food samples was done at the respective state public health laboratories. From 1999 to 2008, 116 outbreaks of foodborne botulism were reported. Of the 48 outbreaks caused by home-prepared foods from the contiguous United States, 38% (18) were from home-canned vegetables. Three outbreaks of Type A botulism occurred in Ohio and Washington in September 2008, January 2009, and June 2009. Home-canned vegetables (green beans, green bean and carrot blend, and asparagus) served at family meals were confirmed as the source of each outbreak. In each instance, home canners did not follow canning instructions, did not use pressure cookers, ignored signs of food spoilage, and were unaware of the risk of botulism from consuming improperly preserved vegetables. Home-canned vegetables remain a leading cause of foodborne botulism. These outbreaks illustrate critical areas of concern in current home canning and food preparation knowledge and practices. Similar gaps were identified in a 2005 national survey of U.S. adults. Botulism prevention efforts should include targeted educational outreach to home canners. |
