MoreSimilar to efforts to understand the structure of the human genome, researchers have examined individual fragments of the genome of Listeria monocytogenes serotype 4b, the strain responsible for most listeriosis outbreaks and 50 percent of sporadic cases. The next step is to assemble the fragments into a complete genomic map, so that researchers can better understand how the bacterium persists in animals, in and on foods, and in processing plants. Researchers also hope to determine how the bacterium affects people.
USDA says the research information is critical to regulatory agencies such as its Food Safety Inspection Service (FSIS) for creating and implementing regulations for safe processing and handling of ready-to-eat foods.
USDA recently proposed food safety measures applicable to all ready-to-eat and all partially heat-treated meat and poultry products, as well as environmental testing requirements intended to reduce the incidence of Listeria monocytogenes in processed meat and poultry plants. The notice regarding the proposed rule, "Performance Standards for the Production of Processed Meat and Poultry Products," appeared in the July 3 edition of the Federal Register. The comment period on the proposal closes Sept. 10.
The Food Defense Strategy Exchange (FDSE) is a forum for food defense professionals to interact and share their knowledge and experiences. At the most recent FDSE, a poll of attendees revealed that approximately two-thirds were either re-evaluating their existing food defense plan, or implementing new food defense plans. In this podcast, Don Hsieh, Director of Commercial and Industrial Marketing at Tyco Integrated Security, discusses this topic and other findings from the exchange, and offers some best practices to proactively protect a company’s brand from food adulteration.
