Ice cream has historically been associated with human cases of infection by various foodborne pathogens. Pathogen introduction into ice cream can occur at various points throughout the production process for a range of reasons, which can be addressed through proper food safety controls. 

A recent study provided insight into the on-farm hygiene characteristics that affect the contamination of milk produced at informal dairy farms in Zimbabwe. The risk variables identified in the study can serve as a foundation for microbial contamination prevention strategies for the sector.

The U.S. Food and Drug Administration (FDA) has published an outline of its research priorities regarding the dairy food safety implications of Highly Pathogenic Avian Influenza (HPAI) H5N1.

The Canadian Food Inspection Agency (CFIA) has provided updates on its sampling and testing activities of retail milk for the presence of highly pathogenic avian influenza (HPAI) viral fragments. Additionally, Health Canada and CFIA recently completed a study on pasteurization’s efficacy against HPAI in milk. 

The U.S. Food and Drug Administration (FDA) has issued a proposed exemption for certain cottage cheese products from the requirements of the Food Traceability Final Rule, fulfilling Subpart 204 of the Food Safety Modernization Act (FSMA 204). 

Intended to inform food safety decision-making, a new risk assessment model developed by researchers at Penn State University helps milk processors evaluate possible consumer exposure to Bacillus cereus from milk subjected to high-temperature, short-time pasteurization.

In this episode of Food Safety Matters, we are joined by influential food safety scientist and Distinguished Service Award recipient, Dr. Kathleen (Kathy) Glass, Ph.D. Topics discussed include Dr. Glass’s academic research and her work on challenge studies for food products; the ongoing HPAI outbreak, considering her expertise in dairy food safety; and her experiences as part of NACMCF.

A novel, chemical- and heat-free egg processing technique utilizing engineered water nanostructures has been shown to effectively inactivate pathogens on eggshells while preserving eggs’ physical and nutritional quality.

University of Edinburgh researchers have conducted a study that affirms the efficacy of standard pasteurization practices against Highly Pathogenic Avian Influenza (HPAI) H5N1.

A recent study has shown the ability of Highly Pathogenic Avian Influenza (HPAI) H5N1 to infect mice fed contaminated raw milk, while, separately, testing conducted by the U.S. Department of Agriculture Food Safety and Inspection Service (USDA-FSIS) has found HPAI traces in muscle from culled dairy cows.
