• Cook– Cook to proper temperatures, check with food
thermometer• Chill– Refrigerate promptly
Shopping

• Thoroughly wrap
Storage Continued

refrigerator• Sanitize cutting boards– 1 Tbs – chlorine bleach– 1 Gal - water
Cooking
• Raw Beef, Pork, Lamb & Veal Steaks, Chops & Roasts– 145*F – internal temp
• Ground Meats & Poultry– 165*
• Why cook ground meat at a higher temperature?
ServingHOT FOOD
• Temperature = 140*• Serving Food– Chafing dishes– Slow cookers– Warming Trays
COLD FOOD
• Temperature = 40*• Serving Food– Nesting dishes in ice– Small Serving Trays
Use Food thermometerHow long does perishable food set out??
Leftovers
• When do we throw food away?• Shallow containers – refrigerate or freeze• Use within _____ days??• Reheat to _______*??
Refreezing
• Defrosted in Refrigerator– Refreeze
• Defrosted by other methods– Cook before refreezing
