Lab Testing: Hunting for Pathogens on Poultry


The mishandling or undercooking of raw chicken meat associated with the recent Foster Farms Salmonella outbreak has sickened nearly 340 people across 20 states and Puerto Rico since March and has caused concern among consumers, consumer groups, and food-safety advocates about the safety of our food system and the efficacy of testing systems designed to… Continue Reading

Food Testing: Labs Test for Pathogens at Different Rates in the U.S. and Europe

Lab testing produce

Microbial testing can be a helpful way to identify pathogen risks for fresh produce, but it’s not a guarantee of safety. That’s why this one option in the toolbox is used differently by Americans and Europeans. Testing in the U.S. varies somewhat from company to company, but it follows similar procedures that were standardized in… Continue Reading

A Salmonella detection technique developed by Minnesota-based conglomerate 3M has been determined to be as effective or more effective than standard methods of detecting Salmonella in seafood and vegetable products, and in environmental samples taken from food processing sites, the Paris-based AFNOR CERTIFICATION expert committee has found. This follows AFNOR CERTIFICATION’s validation in December of… Continue Reading

Campylobacter Screening Method Holds Promise for Detecting Outbreak Source


In a new study, a team of California-based scientists shows that by targeting and analyzing a specific gene in Campylobacter, labs can screen dozens of isolates of the bacteria to find the handful most likely to be the source of an outbreak. Unlike other enteric bacteria, such as E. coli O157:H7, Campylobacter is so diverse… Continue Reading

MDP Shuts Down; USDA Testing of Produce for Pathogens Halted


The Microbiological Data Program, which used to conduct 80 percent of all federal produce testing for pathogens like Salmonella and Listeria, officially shut down on December 31, a U.S. Department of Agriculture official confirmed. The $4.5 million program had been in shutdown mode since mid-November. State agriculture departments, which tested samples of leafy greens, melons,… Continue Reading

Rapid Tests Less Effective in Identifying Foodborne Illness Sources


New tests that detect common foodborne pathogens more rapidly are less likely to trace contamination to the source, since they provide less specific information than older, slower tests, say public health officials. As a consequence, sources of foodborne illnesses outbreaks will not be identified as quickly, state epidemiologists told the Scientific American in a report… Continue Reading

STEC Derived HUS: Infection or Toxemia?



For some time now, the worldwide food supply has been under attack by a bacterium we know well as a generally non-trouble-making resident of the human colon (Escherichia coli), which has lately been possessed of a terrible “new” weapon in the form of Shiga toxin. We call this beast “Shiga toxin-producing  E. coli” (STEC). We… Continue Reading
