Final answer:
Food can become contaminated through poor hygiene, cross-contamination, and failure of temperature control.
Step-by-step explanation:
People can contaminate food through poor hygiene, cross-contamination, and failure of temperature control.
- Poor hygiene: Food can become contaminated when people handle or prepare food with unwashed hands or when infected individuals fail to wash their hands before handling food.
- Cross-contamination: Microbes can be transferred from one food to another when raw foods, such as eggs or raw meat, come into contact with ready-to-eat foods, like fruits and vegetables.
- Failure of temperature control: If food is not stored or cooked at the correct temperatures, bacteria can grow and contaminate the food.
