Contamination Control

A federal appeals court has overturned the U.S. Environmental Protection Agency’s (EPA’s) 2021 ban on all uses of the toxic pesticide chlorpyrifos in food crops.

The Swedish Food Agency's sampling of pesticide residues in food during 2021 has shown that, similarly to previous years, the majority of foods tested did not contain pesticides that exceeded EU maximum residue limits (MRLs), although rice was the biggest offender.

The U.S. Food and Drug Administration (FDA) recently released a factsheet on the 2022 Food Code definition and requirements for “in-shell product,” which is a sub-category of molluscan shellfish that requires special parameters for safe handling.

The European Food Safety Authority Panel on Biological Hazards (EFSA BIOHAZ) recently produced a report on the microbiological hazards associated with water used in postharvest handling and processing of fresh and frozen fruits, vegetables, and herbs.

A recent study funded by the U.S. National Institutes of Health (NIH) has provided strong evidence linking the ingestion of per- and polyfluoroalkyl substances (PFAS), which are present in food packaging and pervasive in drinking water, to thyroid cancer.

A recent study led by the U.S. Centers for Disease Control and Prevention (CDC) investigated factors that could contribute to cross-contamination of food in restaurants, and observed more frequent contamination actions in establishments lacking food safety certification, food safety training, and handwashing policies.

Due to concerns about harms to human health, the U.S. Food and Drug Administration (FDA) has proposed to revoke the regulation that authorizes the use of brominated vegetable oil (BVO) in food. The agency also announced its intent to review three other possibly toxic, FDA-regulated food additives that were recently banned in the state of California, and announced that a decision about red dye 3 is forthcoming.

A recent study has demonstrated the efficacy of antimicrobial blue light technology for the inactivation of both dried cells and biofilms of Listeria monocytogenes on surfaces found in food processing environments. 

A recent Joint Food and Agriculture Organization of the United Nations (FAO)/World Health Organization (WHO) Expert Consultation on Risks and Benefits of Fish Consumption has concluded that, while the nutritional and health value of eating fish is undeniable, more research is required about the toxic effects of exposure to methylmercury and dioxins from consuming fish. 

PFAS concentrations, which do not break down easily in the body, tend to increase rather than diminish over time. In light of these concerns and the prevalence of PFAS in consumer products like food packaging, many state and local governments, as well as public interest organizations, have begun enacting or promoting legislation that would regulate the implementation of PFAS in consumer products.
