Assessment of chemical exposures investigation after fire at an industrial chemical facility in Winnebago County, Illinois
Nakayama JY , Surasi K , Owen LR , Johnson M , Martell S , Kittler A , Lopatin P , Patrick S , Mertzlufft C , Horton DK , Orr M . J Environ Health 2023 85 (7) 8-15 After a chemical fire, an investigation assessed health effects by using syndromic surveillance to monitor emergency department (ED) visits, a general health survey to assess the general public, and a first responders health survey to assess first responders. A total of four separate multivariable logistic regression models were developed to examine associations between reported exposure to smoke, dust, debris, or odor with any reported symptom in the general public. Syndromic surveillance identified areas with increased ED visits. Among general health survey respondents, 45.1% (911 out of 2,020) reported at least one symptom. Respondents reporting exposure to smoke, dust, debris, or odor had 4.5 (95% confidence interval (CI) [3.7, 5.5]), 4.6 (95% CI [3.6, 5.8]), 2.0 (95% CI [1.7, 2.5]), or 5.8 (95% CI [4.7, 7.3]) times the odds of reporting any symptom compared with respondents not reporting exposure to smoke, dust, debris, or odor, respectively. First responders commonly reported contact with material and being within 1 mi of the fire ≥5 hr; 10 out of 31 of first responders reported at least one symptom. There was high symptom burden reported after the fire. Results from our investigation might assist the directing of public health resources to effectively address immediate community needs and prepare for future incidents. © 2023, National Environmental Health Association.

Elevated exposures to respirable crystalline silica among engineered stone fabrication workers in California, January 2019-February 2020
Surasi K , Ballen B , Weinberg JL , Materna BL , Harrison R , Cummings KJ , Heinzerling A . Am J Ind Med 2022 65 (9) 701-707 BACKGROUND: Workers fabricating engineered stone face high risk for exposure to respirable crystalline silica (RCS) and subsequent development of silicosis. In response, the California Division of Occupational Safety and Health (Cal/OSHA) performed targeted enforcement inspections at engineered stone fabrication worksites. We investigated RCS exposures and employer adherence to Cal/OSHA's RCS and respiratory protection standards from these inspections to assess ongoing risk to stone fabrication workers. METHODS: We extracted employee personal air sampling results from Cal/OSHA inspection files and calculated RCS exposures. Standards require that employers continue monitoring employee RCS exposures and perform medical surveillance when exposures are at or above the action level (AL; 25 μg/m(3) ); exposures above the permissible exposure limit (PEL; 50 μg/m(3) ) are prohibited. We obtained RCS and respiratory protection standard violation citations from a federal database. RESULTS: We analyzed RCS exposures for 152 employees at 47 workplaces. Thirty-eight (25%) employees had exposures above the PEL (median = 89.7 μg/m(3) ; range = 50.7-670.7 μg/m(3) ); 17 (11%) had exposures between the AL and PEL. Twenty-four (51%) workplaces had ≥1 exposure above the PEL; 7 (15%) had ≥1 exposure between the AL and PEL. Thirty-four (72%) workplaces were cited for ≥1 RCS standard violation. Twenty-seven (57%) workplaces were cited for ≥1 respiratory protection standard violation. CONCLUSIONS: Our investigation demonstrates widespread RCS overexposure among workers and numerous employer Cal/OSHA standard violation citations. More enforcement and educational efforts could improve employer compliance with Cal/OSHA standards and inform employers and employees of the risks for RCS exposure and strategies for reducing exposure. |
Notes from the field: Self-reported health symptoms following petroleum contamination of a drinking water system - Oahu, Hawaii, November 2021-February 2022
Troeschel AN , Gerhardstein B , Poniatowski A , Felton D , Smith A , Surasi K , Cavanaugh AM , Miko S , Bolduc M , Parasram V , Edge C , Funk R , Orr M . MMWR Morb Mortal Wkly Rep 2022 71 (21) 718-719 In late November 2021, the Hawaii Department of Health (HDOH) received reports from Oahu residents of a fuel-like odor coming from their drinking water (1), which was later determined to be related to a November 20, 2021, petroleum (jet fuel) leak at the Red Hill Bulk Fuel Storage Facility. The petroleum leak contaminated the Joint Base Pearl Harbor-Hickam water system,* which supplies an estimated 9,694 civilian and military households (2), in addition to schools and workplaces. HDOH issued a drinking water advisory on November 30, 2021 (1), which was not lifted for all affected zones until March 18, 2022.† Persons in thousands of households were offered temporary housing, and alternative drinking water was provided to users of affected water. HDOH requested epidemiologic assistance (Epi-Aid) from CDC/Agency for Toxic Substances and Disease Registry (ATSDR) to assess the incident’s impact on civilian health in the affected area; this was later expanded to include military-affiliated persons. |
Twelve-Month Follow-up of Early COVID-19 Cases in the United States: Cellular and Humoral Immune Longevity.

Open Forum Infect Dis 2022 9 (3) ofab664 We quantify antibody and memory B-cell responses to severe acute respiratory syndrome coronavirus 2 at 6 and 12 months postinfection among 7 unvaccinated US coronavirus disease 2019 cases. All had detectable S-specific memory B cells and immunoglobulin G at both time points, with geometric mean titers of 117.2 BAU/mL and 84.0 BAU/mL at 6 and 12 months, respectively. |
Notes from the Field: Deployment of an Electronic Self-Administered Survey to Assess Human Health Effects of an Industrial Chemical Facility Fire - Winnebago County, Illinois, June-July 2021
Surasi K , Nakayama JY , Johnson M , Martell S , Patrick S , Owen LR , Horton DK , Orr M . MMWR Morb Mortal Wkly Rep 2021 70 (49) 1715-1716 On June 14, 2021, an industrial fluid and grease manufacturing facility in Winnebago County, Illinois, (population = 285,350) (1) caught fire, releasing smoke, dust, and debris for 4 days and prompting local authorities to issue a precautionary 1-mile (1.5-km) evacuation order and 3-mile (5-km) masking advisory around the location of the facility during this time. Review of Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE) data during this time demonstrated increased emergency department visits in five zip codes downwind of the fire. In response, the Winnebago County Health Department (WCHD), Illinois Department of Public Health, and Agency for Toxic Substances and Disease Registry (ATSDR) collaborated to investigate the fire’s effect on human health. |
Effectiveness of Abbott BinaxNOW Rapid Antigen Test for Detection of SARS-CoV-2 Infections in Outbreak among Horse Racetrack Workers, California, USA.
Surasi K , Cummings KJ , Hanson C , Morris MK , Salas M , Seftel D , Ortiz L , Thilakaratne R , Stainken C , Wadford DA . Emerg Infect Dis 2021 27 (11) 2761-2767 The Abbott BinaxNOW rapid antigen test is cheaper and faster than real-time reverse transcription PCR (rRT-PCR) for detecting severe acute respiratory syndrome coronavirus 2. We compared BinaxNOW with rRT-PCR in 769 paired specimens from 342 persons during a coronavirus disease outbreak among horse racetrack workers in California, USA. We found positive percent agreement was 43.3% (95% CI 34.6%-52.4%), negative percent agreement 100% (95% CI 99.4%-100%), positive predictive value 100% (95% CI 93.5%-100%), and negative predictive value 89.9% (95% CI 87.5%-92.0%). Among 127 rRT-PCR-positive specimens, the 55 with paired BinaxNOW-positive results had a lower mean cycle threshold than the 72 with paired BinaxNOW-negative results (17.8 vs. 28.5; p<0.001). Of 100 specimens with cycle threshold <30, a total of 51 resulted in positive virus isolation; 45 (88.2%) of those were BinaxNOW-positive. Our comparison supports immediate isolation for BinaxNOW-positive persons and confirmatory testing for negative persons. |
