FAQ: What Methods Can Prevent Biological Contamination?

Properly cooking and cooling foods and avoiding cross-contamination generally will prevent the growth of most bacteria and fungi. Foods should be cooked at the temperatures listed in their directions and for the appropriate amount of time to kill bacteria.

How can biological contamination be avoided?

To minimize the risk of biological food contamination occurring in your food business, always: keep high-risk foods (e.g. meat, poultry, dairy, eggs) out of the Temperature Danger Zone** purchase, store, thaw, prepare, cook and serve high-risk foods properly.

What are two ways to prevent contamination from biological hazards?

Biological Hazard Prevention Kill steps used prior to packaging is necessary, such as cooking thoroughly or pasteurization of milk and juices. Use of packaging technologies during processing like vacuum sealing hinders bacterial growth. Proper temperature management for storage can dramatically reduce microbe growth.
