The Summary Amid the E. coli outbreak believed to be linked to onions served at McDonald’s, food safety experts say some types of fresh produce carry extra risk. An E. coli outbreak that has sickened at least 75, killing one, is a reminder of the contamination risk that can plague certain types of fresh produce, according to food safety experts. Though the investigation is ongoing, federal officials suspect prewashed, slivered onions that were served raw on McDonald’s Quarter Pounders are the likely source of the E. coli outbreak. So it can take only a few cells to get someone very sick,” said Kali Kniel, professor of microbial food safety at the University of Delaware. The food safety experts interviewed also said they steer clear of rare or undercooked meat, poultry, fish and eggs, and don’t drink unpasteurized milk.
