Food - hygiene and sanitation

Definition    Return to top

Food safety refers to the conditions and practices that preserve the quality of food to prevent contamination and foodborne illnesses.

Function    Return to top

Food can be contaminated in many different ways. Some food products may already contain bacteria or parasites. The germs can be spread during the packaging process if the food products are not handled properly. Failure to cook or store the food properly can cause further contamination.

Properly handling and preparing food greatly reduces the risks of getting foodborne illnesses.

Food Sources    Return to top

All foods can become contaminated. Higher risk foods include red meats and poultry; eggs; cheese and dairy products; raw sprouts; and raw fish or shellfish.

Side Effects    Return to top

Poor food handling and inadequate food safety can cause infection (foodborne illness). Symptoms of foodborne illness vary, but usually include stomach problems. Foodborne illness may be severe and life-threatening, especially in young children, older adults, pregnant women, and people with weakened immune systems.
