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.

In light of the ongoing Highly Pathogenic Avian Influenza (HPAI) H5N1 outbreak that has been affecting dairy cattle herds in the U.S., the Canadian Food Inspection Agency (CFIA) sampled and tested milk at retail to determine the presence of HPAI viral fragments.

To investigate the potential impact of more widespread adoption of food irradiation, CDC analyzed a decade (2009–2020) of U.S. foodborne illness outbreak data for four significant foodborne pathogens, and found 155 outbreaks linked to irradiation-eligible foods that had not been irradiated.

FDA recently revealed results of a survey that found HPAI H5N1 genetic material in one in five retail milk samples; additional testing is required to understand the possible presence and risk of intact, infectious virus. Supported by other studies showing the efficacy of pasteurization against HPAI, FDA maintains its position that the U.S. milk supply is safe.
