What potential consequence exists for consumers from eating unwashed fruits and vegetables?

Eating unwashed fruits and vegetables can expose consumers to harmful substances such as pesticides, bacteria, and soil contamination. These harmful substances can lead to foodborne illnesses, which can manifest as nausea, vomiting, diarrhea, and other gastrointestinal issues. Pesticides, although regulated, may remain on the surface of fruits and vegetables, and without washing, the risk of ingesting these chemicals increases. Additionally, produce can carry pathogens like E. coli, Salmonella, and Listeria, which can thrive on unwashed items and cause severe health problems. Thus, washing fruits and vegetables is a critical practice to reduce the risk of contamination and safeguard health.
