What part of the body is the most common vehicle for transferring food poisoning bacteria?

• A. the feet
• B. the hands
• C. the hair
• D. the mouth

Answer: (B)

Hands are the most common vehicle for transferring food poisoning bacteria because they are used to handle raw ingredients, finished foods, and many surfaces in contact with food. Bacteria can live under fingernails and in skin folds, and without proper handwashing they move from contaminated areas onto foods that are eaten without further cooking. This is why frequent, thorough handwashing and avoiding bare-handed contact with ready-to-eat foods are emphasized in HACCP plans as essential hygiene practice. The other choices are less influential in everyday food handling: feet aren’t routinely used to touch food; hair can contaminate if strands fall into food but is less direct; and the mouth mainly acts as the source of bacteria when eating or coughing into food, not as the typical vehicle for transferring bacteria during food preparation. The bottom line is that hands drive cross-contamination in most food operations.
