The FDA originally had identified Taylor Farms de Mexico as the Taco Bell shredded iceberg lettuce supplier connected to the parasite outbreak that has sickened hundreds across the country.
The department, which has reported 2,640 cases as of July 13, noted other food items can’t be completely ruled out since no specific type of produce, grower or supplier has been identified as the source.
FoodNet, which is a collaboration between the CDC, USDA FSIS, FDA and 10 state health departments, previously tracked infections caused by eight pathogens. As of July, monitoring is required for only two pathogens.
High humidity exposure and the water-soaking symptom caused by X. vitians also enhance the ability of salmonella to rapidly grow in lettuce, and climate change is predicted to increase humid periods.
