Slacking Process of gradually thawing frozen food in preparation for deep-frying. Minimum Internal Temperature The required minimum temperature the internal portion of food must reach to sufficiently reduce the number of microorganisms that might be present. This temperature is specific to the type of food being cooked. Food must reach and hold its required internal temperature for a specific amount of time. Instructor Notes 7-4

The Four Acceptable Methods for Thawing Food
The Four Acceptable Methods for Thawing Food In a refrigerator, at 41F (5C) or lower Submerged under running potable water, at a temperature of 70F (21C) or lower In a microwave oven, if the food will be cooked immediately after thawing As part of the cooking process The Four Acceptable Methods for Thawing Food In a refrigerator, at 41F (5C) or lower Submerged under running potable water, at a temperature of 70F (21C) or lower Instructor Notes If food is thawed improperly, foodborne microorganisms that may be present can rapidly grow to unsafe levels. When thawing food under running water, water flow must be strong enough towash loose food particles into the overflow drain. When thawing food as part of the cooking process, the product must meet the required minimum internal cooking temperature. In a microwave oven, if the food will be cooked immediately after thawing As part of the cooking process 8-2

When preparing raw meat, fish, and poultry, foodhandlers should:
Preparing Raw Meat, Fish, and Poultry When preparing raw meat, fish, and poultry, foodhandlers should: Wash their hands properly Use clean and sanitized work areas, equipment, and utensils Remove only as much product from storage as necessary Store prepared meat, or cook it as quickly as possible When preparing raw meat, fish, and poultry, foodhandlers should: Wash their hands properly Use clean and sanitized work areas, equipment, and utensils Remove only as much product from storage as necessary Store prepared meat, or cook it as quickly as possible Instructor Notes If gloves are worn when preparing these items, they should be changed before starting each new task. Foodhandlers should remove from refrigerated storage only as much product as can be prepared at one time. When returning prepared meat to refrigeration, it should be stored properly to prevent cross-contamination. 8-3

When preparing salads containing potentially hazardous ingredients:
Preparing Salads Containing Potentially Hazardous Food When preparing salads containing potentially hazardous ingredients: Only use meat and poultry that was safely handled prior to use Do not use ingredients until ready for use Chill utensils prior to using them Preparing the salads in small batches When preparing salads containing potentially hazardous ingredients: Only use meat and poultry that was safely handled prior to use Do not use ingredients past their use-by dates Refrigerate ingredients until ready for use Chill utensils prior to using them Prepare the salads in small batches Instructor Notes Chicken, tuna, egg, pasta, and potato salads all have been known to cause foodborne-illness outbreaks. They are made from food that can support the rapid growth of microorganisms. Since these food items usually will not be cooked after preparation, there is no chance to kill microorganisms that can be introduced during preparation. Make sure leftover meat and poultry have been properly cooked, held, cooled, and stored before using it in salads. Make sure leftovers used for salad have not been left in the refrigerator too long. Leftover meat and poultry should be discarded after seven days if refrigerated at 41°F (5°C). Prepare food in small batches so large amount amounts of food do not sit out at room temperature for long periods of time. 8-4

Prepping Specific Food
When prepping produce: Make sure produce does not touch surfaces exposed to raw meat and poultry Refrigerate and hold sliced melons, cut tomatoes, and cut leafy greens at 41°F (5°C) or lower Do not serve raw seed sprouts if you primarily serve high-risk populations

Prepping Specific Food
When prepping produce: Wash it thoroughly under running water before: Cutting Cooking Combining with other ingredients Produce can be washed in water containing ozone to sanitize it Check with your local regulatory authority Instructor Notes Wash fruit and vegetables thoroughly under running water, The water should be a little warmer than the produce. Pay special attention to leafy greens such as lettuce and spinach. Remove the outer leaves, and pull the lettuce or spinach completely apart and rinse thoroughly. Produce can be washed in water containing ozone to sanitize it. Check with your local regulatory authority to see if this is allowed in your jurisdiction.

When preparing eggs and egg mixtures:
Preparing Eggs and Egg Mixtures When preparing eggs and egg mixtures Handle pooled eggs (if allowed) with special care Clean and sanitize equipment and utensils used to prepare eggs Use pasteurized shell eggs or egg products when : Serving high-risk populations Preparing dishes requiring little or no cooking. When preparing eggs and egg mixtures: Handle pooled eggs (if allowed) with special care Clean and sanitize equipment and utensils used to prepare eggs Use pasteurized shell eggs or egg products when: Serving high-risk populations Preparing dishes requiring little or no cooking Instructor Notes Untreated shell eggs are considered potentially hazardous because they are able to support the rapid growth of microorganisms. Pooled eggs are eggs that are cracked open and combined into a common container. They must be handled with care because bacteria in one egg can spread to the rest of them. Pooled eggs must also be cooked promptly after mixing, or should be stored at 41F (5C) or lower. Containers used to hold pooled eggs must be washed and sanitized before holding another batch. Never use empty food containers to store chemicals or put food in empty chemical containers. Eggs dishes requiring little or no cooking include mayonnaise, eggnog, Caesar salad dressing, and hollandaise sauce. 8-5

When battering food: When breading food:
Preparing Batter and Breading When battering food: Consider making batter with pasteurized eggs Prepare batter in small batches Throw out unused batter after each shift When breading food: Refrigerate it as quickly as possible if it will be used later Throw out unused breading after each shift When battering food: Consider making batter with pasteurized eggs Prepare batter in small batches Throw out unused batter after each shift When breading food: Refrigerate it as quickly as possible if it will be used later Throw out unused breading after each shift Instructor Notes Batters and breading prepared with milk or eggs are potentially hazardous. Therefore, unneeded batter should be stored at 41F (5C) or lower. You should never use the same batter or breading for more than one product. Throw out any unused batter at the end of the shift. 8-6

If your establishment primarily serves high-risk populations, do not serve raw seed sprouts. Instructor Notes Cut melons should be held at 41°F (5°C) or lower. Raw seed sprouts should not be served if the establishment primarily serves a high-risk population. 8-7 Photo courtesy of Tony Soluri and Charlie Trotter

Soaking or Storing Produce in Water
When soaking or storing produce in standing water or an ice-water slurry, do not mix different items or multiple batches.

Fresh Juice Fresh Juice If juice is prepared and packaged on site for sale at a later time, a variance from the regulatory agency is needed.

Fresh Juice Fresh Juice The juice must also be treated according to an approved HACCP plan OR label with the following phrase: Warning: this product has not been pasteurized and therefore may contain harmful bacteria that can cause serious illness in children, the elderly and people with weakened immune systems.

Ice When scooping ice from an ice machine:
Ice When scooping ice from an ice machine Use a sanitized container and scoop Store outside of the ice machine in a sanitary location Do not use a glass as a scoop Do not let hands come in contact with ice When scooping ice from an ice machine: Use a sanitized container and scoop Store scoops outside of the ice machine in a sanitary location Do not use a glass as a scoop Do not let hands come in contact with ice Instructor Notes Ice used as an ingredient or used to chill food must be made from potable water. Ice used to chill food or beverages should never be used as an ingredient. 8-8

Preparation Practices That Require a Variance
A variance is required whenever an establishment: Smokes food or uses food additives as a method of food preservation. Cures food. Custom-processes animals for personal use. Packages food using a reduced-oxygen packaging method. Serves raw or undercooked fish, eggs, shellfish or meat (excluding steaks). Sprouts seeds or beans. Using food additives or components to preserve or alter food so it no longer needs time and temperature control for safety Packaging fresh juice on-site for sale at a later time, unless the juice has a warning label

Preparation Practices That Require a Variance
You need a variance if prepping food in these ways: continued Packaging food using a reduced-oxygen packaging (ROP) method Sprouting seeds or beans Offering live, molluscan shellfish from a display tank Custom-processing animals for personal use (i.e. dressing a deer) Instructor Notes Clostridium botulinum and Listeria monocytogenes are risks to food packaged using a reduced-oxygen packaging method. This includes MAP, vacuum-packed and sous vide food.

Cooking Food Cooking Food When cooking potentially hazardous food, the internal portion must: Reach the required minimum internal temperature Hold that temperature for a specific amount of time. When cooking potentially hazardous food, the internal portion must: Reach the required minimum internal temperature Hold that temperature for a specific amount of time Instructor Notes To reduce the number of microorganisms that might be present on food to safe levels, it must be cooked to its required minimum internal temperature. That temperature varies from product to product. Minimum standards have been developed for most cooked food and are included in local and state health codes. The only way to be certain food has reached the required minimum internal cooking temperature is to check it using a calibrated thermometer. Potentially hazardous food that is not cooked to its required minimum internal temperature generally does not pose an unacceptable risk of foodborne illness to the healthy customer. However, if a customer is in a group at risk for foodborne illness, consuming raw or undercooked, potentially hazardous food could possibly increase the risk of illness, sometimes seriously. High-risk customers should be advised of the potential risk if they ask about or specifically request undercooked food or any potentially hazardous food (or ingredient) that is raw or not fully cooked. 8-9

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 6-10

Cooling Requirements 135°F to 70°F within 2 hours and then from 70°F to 41°F or lower in an additional 4 hours Cool potentially hazardous food from: 135°F to 70°F (57°C to 21°C) within 2 hours and then from 70°F to 41°F (21°C to 5°C) or lower in an additional 4 hours Instructor Notes Since only two hours are allowed for cooling food from 135°F to 70°F (57°C to 21°C), potentially hazardous food is passed through the middle of the temperature danger zone (its most dangerous part) quickly and safely. If the food has not reached 70°F (21°C) within two hours, it must be discarded or reheated to 165°F (74°C) for fifteen seconds within two hours and then recooled. Some jurisdictions do not require two-stage cooling and only require food to be cooled to 41°F (5°C) or lower in less than four hours. 8-24 Icon courtesy of the International Association for Food Protection

Several factors affect how quickly food will cool, including:
Cooling Food Several factors affect how quickly food will cool, including: Thickness or density of the food The container in which the food is stored Several factors affect how quickly food will cool, including: Thickness or density of the food The container in which the food is stored Instructor Notes The thicker the food, the more slowly it will cool. Stainless steel containers transfer heat from food faster than plastic, and shallow pans transfer heat faster than deep pans. Refrigerators should not be used to cool hot food, since most are not designed to cool it quickly. 8-25

Safe methods for cooling food include:
Methods for Cooling Food Safe methods for cooling food include: Reducing the quality or size of the food Using ice-water baths Using a blast chiller Stirring the food Safe methods for cooling food include: Reducing the quantity or size of the food Using ice-water baths Using a blast chiller Instructor Notes To reduce the quantity or size of the food you are cooling, cut large food items into smaller pieces, or divide large containers of food into smaller containers. After food is divided into smaller quantities, it can be cooled in an ice-water bath by placing the pots or pans into a sink or large pot filled with ice water. Stirring food will help it cool faster and more evenly. Some manufacturers make plastic paddles that can be filled with water and frozen. Stirring food with these cold paddles cools food quickly. Other methods for cooling food include: Adding ice or cool water as an ingredient. This works for recipes requiring water as an ingredient. Using a steam-jacketed kettle (if properly equipped). Simply run cold water through the jacket to cool food in the kettle. Stirring the food 8-26

Once food has cooled to 70°F (21°C), store it by:
Storing Cooked Food Once food has cooled to 72°F, store it by: Placing it in shallow stainless steel pans Placing pans on top shelves in refrigeration units Positioning pans so air circulates around them Monitoring it to ensure cooling to 41°F or lower in 4 hours Once food has cooled to 70°F (21°C), store it by: Placing it in shallow stainless steel pans Placing pans on top shelves in refrigeration units Positioning pans so air circulates around them Monitoring it to ensure cooling to 41°F (5°C) or lower in 4 hours 8-27
