What food is linked to 46% of foodborne illness outbreaks?

• A. Dairy Products
• B. Poultry
• C. Seafood
• D. Raw Produce

Answer: (D)

The question is about which food category is most often identified as the source in foodborne illness outbreaks, highlighting how outbreak data reveal common vehicles of contamination. Raw produce leads the way because a large portion of produce is eaten without a heat step that would kill pathogens, so any contamination can reach the consumer. Contamination can occur at many points along a long and complex supply chain—from growing practices (irrigation water, manure, proximity to animals) to harvesting, processing, packing, and distribution—making it harder to prevent and easier to transmit to many people.

Pathogens can be introduced to produce by contaminated water, soil, or handling, and even viruses like norovirus can be spread to produce via infected food handlers. Since produce spans a wide variety of items—leafy greens, sprouts, melons, berries, and other fresh fruit and vegetables—the opportunities for contamination and exposure are numerous, and many outbreaks are attributed to raw produce when investigated.

In contrast, dairy, poultry, and seafood often involve heat treatment, cooking, or pasteurization that reduce pathogen risk, or have more controlled processing steps, which can result in a smaller share of outbreaks tied to them. Overall, the combination of being commonly eaten raw and the complexity of preventing contamination across the supply chain makes raw produce the category most frequently implicated in outbreaks.
