The Wadsworth Center Fellowship Program Committee hosted the Winter Fellow Research Symposium on January 22, 2026, at the David Axelrod Institute (DAI) and the Life Sciences Innovation Building (LSIB) Collaboratory. Eight fellows representing three Divisions—the Division of Environmental Health Sciences, Division of Infectious Diseases, and Division of Genetics—participated in the event. 

Beginning in early November 2025, the U.S. Food and Drug Administration (FDA), in collaboration with the Centers for Disease Control and Prevention (CDC), initiated an investigation into a multistate outbreak of infant botulism associated with ByHeart Whole Nutrition powdered infant formula. Early epidemiologic findings demonstrated a strong association between illness and consumption of the product, prompting a voluntary recall.

The Wadsworth Center investigated the deaths of five common loons (Gavia immer) collected from New York State waters for suspected type E botulism, a rare type that is usually associated with birds and aquatic environments. Four of the birds were recovered from Lake Erie in Erie County, and one was collected from Lake Ontario in Oswego County. Liver samples from all five loons, along with gastrointestinal contents (pooled samples from the Lake Erie loons and an individual sample from the Lake Ontario loon), were collected on November 19, 2025. 

The Environmental Laboratory Approval Program (ELAP) within the Wadsworth Center at the New York State Department of Health has regulatory oversight responsibility for laboratories that test environmental samples collected in New York State.  These laboratories analyze samples for a wide range of toxins, harmful microorganisms, carcinogens, and other substances that may affect public health and the environment. 

Nicole Cairns, Assistant Director of the Wadsworth Center, was elected Chair of The NELAC Institute (TNI) Chemistry Expert Committee on January 7, 2026.  TNI is a national, nonprofit organization whose mission is to promote the generation of environmental measurement data of known and documented quality through the development and maintenance of consensus standards.  These standards are used to accredit environmental laboratories, accreditation bodies, and proficiency testing providers nationwide.  Ms.

Substance use disorder (SUD) is a significant public health challenge in the United States.  According to the 2021 National Survey on Drug Use and Health, an estimated 29.5 million individuals aged 12 and older had an alcohol use disorder, while 24 million had a drug use disorder.  Beyond the direct health impacts of substance use, individuals with SUD may also face increased exposure to harmful environmental chemicals that can further compromise health.  Drugs produced through clandestine and unregulated manufacturing processes can expose individuals to a range of contaminan

The Wadsworth Center has identified Borrelia mayonii in blacklegged ticks (Ixodes scapularis) collected in New York State – the first time this Lyme disease-like pathogen has been detected outside the upper Midwest. B.

The Clinical Laboratory Evaluation Program (CLEP) within the Wadsworth Center regulates clinical laboratory testing in New York State. Among its regulatory responsibilities, CLEP is currently the only regulatory agency in the United States that conducts formal review of Laboratory Developed Tests (LDTs). While clinical laboratories outside New York State may develop and use LDTs without FDA approval, any laboratory seeking to test New York State specimens must obtain CLEP approval. 

A new research publication coauthored by the Wadsworth Center’s Division of Environmental Health Sciences highlights a link between secondhand tobacco smoke (SHS) exposure and sleep disturbances in children. SHS remains a significant public health concern, and emerging evidence suggests it can adversely affect sleep through both biological and behavioral mechanisms.
