To keep food safe throughout the flow of food:Prevent cross-contaminationPrevent time-temperature abuse

4-2

The Flow of FoodSlide3

Separate equipment:Use separate equipment for each type of foodClean and sanitize:

Clean and sanitize all work surfaces, equipment, and utensils after each task

4-3

Preventing Cross-ContaminationSlide4

Prep food at different times:Prepare raw meat, fish, and poultry at different times than ready-to-eat food (when using the same prep table)Buy prepared food:

Buy food items that do not require much prepping or handling

4-4

Preventing Cross-ContaminationSlide5

Time-temperature control:Food held in the range of 41ºF to 135ºF (5ºC to 57º

C) has been time-temperature abused Food has been time-temperature abused whenever it is handled in the following ways:Cooked to the wrong internal temperatureHeld at the wrong temperatureCooked or reheated incorrectly

4-5

Preventing Time-Temperature AbuseSlide6

Avoid time-temperature abuse:Monitor time and temperatureMake sure the correct kinds of thermometers are

availableRegularly record temperatures and the times they are takenMinimize the time that food spends in the temperature danger zoneTake corrective actions if time-temperature standards are not met

Thermocouples and thermistors:Measure temperature through a metal probeDisplay temperatures digitally

Come with interchangeable probesImmersion probeSurface probePenetration probeAir probeHave a sensing area on the tip of their probes

4-8

Monitoring Time and TemperatureSlide9

Infrared (laser) thermometers:Use them to measure the surface temperature of food and equipment

Hold them as close to the food or equipment as possible Remove anything between the thermometer and the food, food package, or equipmentFollow the manufacturer’s guidelines

4-9

Monitoring Time and TemperatureSlide10

Time-temperature indicators (TTI):Monitor both time and temperature

Are attached to packages by the supplierA color change appears on the device when time-temperature abuse has occurred Maximum registering thermometer:Indicates the highest temperature reached during use Used where temperature readings cannot be continuously observed

4-10

Monitoring Time and TemperatureSlide11

When using thermometers:Wash, rinse, sanitize, and air-dry thermometers before and after using themCalibrate them before each shift to ensure

accuracyMake sure thermometers used to measure the temperature of food are accurate to +/- 2ºF or +/- 1ºC Only use glass thermometers if they are enclosed in a shatterproof casing

4-11

General Thermometer GuidelinesSlide12

When using thermometers: Insert the thermometer stem or probe into the thickest part of the product (usually the center)

Take more than one reading in different spotsWait for the thermometer reading to steady before recording the temperature
