Dr. Siyun Wang, a professor of food safety engineering, underscores the risks of consuming raw vegetables, which can harbor harmful bacteria like E. coli. Contamination can occur through various channels, including polluted irrigation water, cross-contamination during handling, or contact with animals in the field. “While cooking effectively kills these pathogens, raw consumption skips this critical step,” Wang notes, emphasizing the importance of thorough washing and proper food handling practices to minimize risks.
The recent E. coli outbreak linked to raw onions in the U.S. highlights how even seemingly safe produce can become hazardous. Wang stresses that these risks aren’t isolated to onions; leafy greens, sprouts, and other raw produce are similarly vulnerable. She advises consumers to stay informed about recalls, wash fresh produce under running water, and prioritize hygiene in the kitchen to reduce the likelihood of foodborne illness.
