Temperature Danger Zone 41°-135° most rapid 70°-125° REF 5-3 2-5 3. Water Activity aw scale range 0.0 to 1.0 The closer to 1.0 the more bacteria grows .85 ideal for bacteria growth. REF 2-5 4. Bacterial Growth starts 1 cell in 1 hour and 20 min 16 cells. In ten hours 1 billion cells. REF 2-6 5. Staph infection 35%-50% Healthy adults carry on skin and in nose. 6. Hand washing water 100°F Scrub 10-15 second Whole process of hand wash 20 seconds REF 4-5 7. Food added as an ingredient with bare hand contact heat food to 145°F REF 4-7 8. Bimetallic stemmed thermometer reads O°F-220°F REF 5-6 9. Temp of boiling 212°F (100°C ) Sea level affects boiling pt. Freezing 32°F (0°C) REF 5-6 10. Measuring Temp Accuracy: +/-2° for measuring temp with Bimetallic stemmed thermometer. Air measurement +/-3° Hanging +/-1.5° REF 5-8 11. Receiving Temps REF 6-5 Temperature criteria for deliveries: Cold TCS food: Receive at 41°F (5°C) or lower, unless otherwise specified Live shellfish: Receive oysters, mussels, clams, and scallops at an air temperature of 45°F (7°C) and an internal temperature no greater than 50°F (10°C) o Once received, the shellfish must be cooled to 41°F (5°C) or lower in four hours Shucked shellfish: Receive at 45°F (7°C) or lower o Cool the shellfish to 41°F (5°C) or lower in four hours 12. Storage Temps Ready to Eat TCS stored 7 days held at 41°F or lower Hot 135°F and higher REF 7-3-4 Temperatures: Store TCS food at an internal temperature of 41°F (5°C) or lower or 135°F (57°C) or higher Store frozen food at temperatures that keep it frozen Make sure storage units have at least one air temperature measuring device; it must be accurate to +/- 3°F or +/- 1.5°C Place the device in the warmest part of refrigerated units, and the coldest part of hot-holding units Storage Date marking: Ready-to-eat TCS food must be marked if held for longer than 24 hours o Date mark must indicate when the food must be sold, eaten, or thrown out Storage Date marking: Ready-to-eat TCS food can be stored for only seven days if it is held at 41°F (5°C) or lower o The count begins on the day that the food was prepared or a commercial container was opened o For example, potato salad prepared and stored on October 1 would have a discard date of October 7 on the label o Some operations write the day or date the food was prepared on the label; others write the useby day or date on the label 13. Storage Fish <41°F Fresh Fish whole flaked or crushed ice self-draining. 14. Eggs can be stored at 45°F REF 7-7 15. Fresh Produce only if it is cut must be <41°F 85-95% relative humidity. Root veg 60°F-70°F dry area container well ventilated. Store onions away from potatoes. REF 7-8 16. UHT Items pasteurized can be held at room temp After opening <41°F REF 7-9 17. Thawing 8-3 4 5 18. 8 must know all temps in this chapter Cooking Requirements for Specific Food Minimum internal cooking temperature: 165°F (74°C) for 15 seconds Poultry—whole or ground chicken, turkey, or duck Stuffing made with fish, meat, or poultry Stuffed meat, seafood, poultry, or pasta Dishes that include previously cooked, TCS ingredients Cooking Requirements for Specific Food Minimum internal cooking temperature: 155°F (68°C) for 15 seconds Ground meat—beef, pork, and other meat Injected meat—including brined ham and flavor-injected roasts Mechanically tenderized meat Ratites including ostrich and emu Ground seafood—including chopped or minced seafood Shell eggs that will be hot-held for service Cooking Requirements for Specific Food Minimum internal cooking temperature: 145°F (63°C) for 15 seconds Seafood—including fish, shellfish, and crustaceans Steaks/chops of pork, beef, veal, and lamb Commercially raised game Shell eggs that will be served immediately Cooking Requirements for Specific Food Minimum internal cooking temperature: 145°F (63°C) for four minutes Roasts of pork, beef, veal, and lamb Alternate cooking times/temperatures o 130°F (54°C) 112 minutes o 131°F (55°C) 89 minutes o 133°F (56°C) 56 minutes o 135°F (57°C) 36 minutes o 136°F (58°C) 28 minutes o 138°F (59°C) 18 minutes o 140°F (60°C) 12 minutes o 142°F (61°C) 8 minutes o 144°F (62°C) 5 minutes Cooking Requirements for Specific Food Minimum internal cooking temperature: 135°F (57°C) Fruit, vegetables, grains (rice, pasta), and legumes (beans, refried beans) that will be hot-held for service Partial Cooking During Preparation If partially cooking meat, seafood, poultry, or eggs or dishes containing these items: NEVER cook the food longer than 60 minutes during initial cooking Cool the food immediately after initial cooking Freeze or refrigerate the food after cooling Heat the food to at least 165˚F (74˚C) for 15 seconds before selling or serving Cool the food if it will not be served immediately or held for service 19. 8-12 know cooling process. Reheating Food reheated for immediate service: Can be reheated to any temperature if it was cooked and cooled correctly Food reheated for hot-holding: Must be reheated to an internal temperature of 165°F (74°C) for 15 seconds within two hours Reheat commercially processed and packaged ready-to-eat food to an internal temperature of at least 135°F (57°C) 20.
