Frozen Storage
* used to hold frozen food at 0F or lower *do not store warm food inside *do not overload units *place frozen food deliveries in the freezer as soon as they are inspected * Defrost freezer除霜 units on a regular basis * slows the growth of microorganisms substantially * Freezing does not kill all microorganisms.
storing shell eggs
1. 45F, do not wash shell eggs 2. keep eggs in refrigerated storage until used:use eggs within 4-5 weeks of packing date
Choosing Suppliers
1. Assure they obtain products form approved sources. Those that are inspected检查 and in compliance服从 with applicable local, state, and federal laws. 2. Are reputable声誉好的 3. Have clean, well-run warehouses. 4. Have a HACCP (Hazard Analysis & Critical Control Points) program in place 5. Train their employees in food safety 6. Use delivery trucks in good condition 7. Deliver consistent product quality when your staff has time to receive them properly
Time-temperature indicators(TTIs)
1. Attached to附属 packaging by the supplier 2. A color change appears in the TTI window if the food have been time-temperature abused during shipment or storage 3. This color change is not reversible可逆的, so you know if the item has been abused 4. TTI allos producers, retailers, and consumers to check at a glance whether perishable易腐坏的 products have been correctly transported and stored
Common types of thermometers

Hold calibration nut with a wrench and rotate thermometer head until it reads 212F (100C) ()On some thermocouples探针电热偶, it may be possible t oppress a reset bottom to adjust the readout
Thermometer Guidelines
1. Clean and sanitize thermometers between uses. Keep thermometers and their storage cases clean 2. Calibrate before each shift or before each day's deliveries. recalibrate if they are dropped, or after they have experienced a severe temperature change 3. Never using glass thermometers(Unless enclosed in a shatterproof casing) to monitor the temperature of food; potentially causing physical contamination. 4. Insert the thermometer stem or probe in to thickest part of the product to check the temperature of food.
Receiving temperature requirements for various types of food:
1. Cold TCS food: 41F or lower, unless otherwise specified 2. Hot TCS food: 135F or higher. 3.

Checking temp. of food items
1. Meat, poultry, and fish: insert the thermometer stem or probe into the thickest part of the feed. 2. other packaged food: Open the package and insert the thermometer stem or probe into the food until the sensing area is immersed.浸入的 3. Shell eggs: Check the air temperature of the delivery truck
inspecting reduced oxygen packaged(ROP)foods
1. Modified atmosphere packaging (MAP): air is removed from a food package and replaced with gases that help extend the product's shelf life 2. Vacuum packed food: processed by removing the air around a product sealed in a package 3. Sous vide food: vacuum packed in individual pouches, partially or fully cooked, and heated for services
Prevent time-temperature abuse:
1. Monitoring: which food items should be checked, how often, and by whom. 2. Tools: check correct kinds of thermometers温度计. Use calibrated 标刻度的thermometers. 3. Recording: have food handlers record temperatures regularly 4. Time and temperature control: limit the time food spends in the TDZ:41-135F(5-57C) a. discard food that spends longer than 4 hours in the TDZ. b. Pathogens especially grow fast between 70F-125F. 5. Corrective actions: Make sure food handlers know what to do when time and temperature standards are not met.
Keep TCS food out of the TDZ (41F-135F)
1. Store deliveries as soon as they have been inspected 2. put prepared food away 3. make sure storage units have at least one air-temprature measuring device. 4. Must be accurate to +/-3F Must be located in the warmest part of refrigerated unites or coldest part of hot holding unit
Temperature-Measuring Devices
1. The common causes of spoilage of chilled food and beverages are too high temperature during storage and transport 2. Emerging intelligent packaging technology can help distributors and retailers easily recognize potentially spoiled products before these products ever hit store shelves.
How to calibrate 校正Thermometers
1. Thermometers can lose their accuracy when they are bumped, dropped, or experience severe temperature change 2. Calibration ensures that a thermometer gives an accurate reading by adjusting it to a known standard. 3. Two acceptable methods of calibration: the Ice-point Method(the most often used) and the boiling-point method

Dry food must be stored: a. at least 6 inches off the floor b. away from walls c. out o direct sunlight d. in a clean area( cool,dry and well ventilated)通风的 4. Moisture and heat are the biggest dangers to dry and canned food.
Infrared (laser) Thermometers
1. Used to measure surface temperature of food/equipment: not designed to measure air temperature or the internal temperature of food 2. quick/ easy to use: less chance for cross-cintamination because they do not require contact with food 3. Distance: Must be held as close to product as possible 4. Barriers: Remove anything between thermometer and the food, food package, or equipment.
FDA(food and drug administration )

Shellfish: shellstock ID tags
1. shellfish must be bought only from approved suppliers. 2. The FDA requires that live, molluscan shellfish carry shell stock identification tags 3. These tags must remain attached to their delivery container until all of the shellfish have been used. 4. Tags that document when and where the shellfish were harvested 5. They must be kept on file for 90 days from the date the last shellfish was used from its delivery container.
Storing Meat,Poultry and fish
1. store them immediately after delivery and inspection in coldest part of the refrigerator 2. frozen meat,poultry and fish should be stored at temperature that will keep it frozen 0F or lower 3. if removed from its original packaging, wrap them in airtight, moisture-proof material or store it in clean and sanitized containers. 4. fresh, whole fish can be packed in crushed ice, and ice beds must be self-draining. 5. ice-packed poultry can be stored in a refrigerator as is, in self-drading containers 6. change the ice and sanitize the container often.
