In 2018, a foodborne pathogen with many unique challenges caused an outbreak of 761 cases of foodborne illness in the United States. An initial outbreak in June, as well as a more recent outbreak affecting 250 people in September 2018, seemed to stem from consumption of contaminated vegetable trays. The CDC has attributed other recent outbreaks of this food-borne illness to contaminated lettuce, basil and cilantro. The outbreak resulted in several food recalls and even caused McDonald’s to stop selling salads in over 3,000 locations.
