A California food manufacturer is recalling more than 92,000 pounds of fully cooked chicken Caesar salad kit products because of possible Listeria monocytogenes (Lm) contamination, according to USDA’s Food Safety and Inspection Service (FSIS).

The first results of a new survey testing for the presence of Campylobacter on fresh, store-bought chickens revealed 59 percent of birds tested positive for the bacteria.

USDA researchers have identified a potential vaccine for Campylobacter in poultry through a study funded by the US Poultry and Egg Association and the association’s foundation.

As the UK’s Food Standards Agency continues food safety week, the agency is calling on people to stop washing raw chicken in an effort to reduce the risk of spreading or contracting Campylobacter.
