Escherichia coli infection is commonly associated with which exposure?

• A. Consuming raw vegetables irrigated with contaminated water.
• B. Contaminated poultry.
• C. Unpasteurized milk.
• D. Spoiled canned foods.

Answer: (A)

Escherichia coli infections are commonly linked to fecal contamination of foods or water, with raw produce being a frequent route when irrigation water or wash water is contaminated. Since raw vegetables aren’t cooked, any E. coli present isn’t killed before eating, allowing illness to occur. Outbreaks have been notably associated with leafy greens and other raw produce exposed to contaminated irrigation water. In contrast, poultry is more often a source of Salmonella or Campylobacter, unpasteurized milk can carry Listeria or Salmonella, and spoiled canned foods point to Clostridium botulinum. So, consuming raw vegetables irrigated with contaminated water best fits the typical exposure for an E. coli infection.
