The second step to maintaining food safety and sanitation is to follow the four basic steps of food safety: clean, separate, cook, and chill. These steps are designed to prevent cross-contamination, kill harmful bacteria, and preserve food quality. To start, wash your hands, utensils, equipment, and surfaces with soap and water before and after handling food. Use a sanitizing solution or a dishwasher to disinfect them. Rinse fruits and vegetables under running water before cutting or peeling them. Additionally, keep raw and cooked foods separate at all times. Use different cutting boards, knives, and containers for different types of food. Store raw meat, poultry, seafood, and eggs in sealed packages or containers and place them on the bottom shelf of the refrigerator or freezer to avoid dripping juices. When cooking, use a food thermometer to check the internal temperature of cooked foods and make sure they reach the safe minimum temperature recommended by the USDA. Furthermore, refrigerate or freeze perishable foods within two hours of purchasing or preparing them. Do not leave foods at room temperature for more than two hours or one hour if the temperature is above 90°F. Thaw frozen foods in the refrigerator, under cold water, or in the microwave, not on the counter. Lastly, divide large portions of food into smaller containers to speed up cooling.
