9 Navigating Food Safety CHAPTER 3 PERSONAL HYGIENE Objectives Explain how people contaminate food Define good personal hygiene Demonstrate how to wash your hands Identify when to wash your hands Describe good glove use practices and proper clothing and behaviors At any stage during preparation and service, there are many ways that a food handler can contaminate food. These include Working while sick Working with uncovered skin wounds Working after being in contact with sick people Poor personal hygiene Our company has policies that clearly outline personal hygiene requirements that crew are to follow at all times. These include Handwashing Hand sanitizer usage Hand care Glove use Personal cleanliness It is important that all food handlers are trained in good personal hygiene. Training must be done at the beginning of a contract and repeated as often as necessary. Supervisors must ensure that everyone is practicing good personal hygiene, and if they observe otherwise, they must discuss with food handlers what they are doing wrong and how they should fix it. One of the best ways to train and supervise is to lead by example. Handwashing is one of the most important parts of good personal hygiene. There are six steps to effective handwashing. These are 1. Wet hands with water that is at least 100 F (38 C) 2. Apply soap 3. Scrub chapter Navigating Food Safety Study Guide 93

10 4. Rinse 5. Dry with paper towel 6. Turn off water You must always use the designated handwashing facilities and ensure they are stocked with soap and disposable towels at all times. Remember when to wash your hands. You must always wash your hands after using the toilet; handling garbage; working with raw meat; touching your hair, face, or clothing; sneezing, coughing, or blowing your nose; handling chemicals; and clearing tables. You must also always wash your hands after eating, drinking, or smoking. It is also important to wash your hands before starting work, touching ready-to-eat food, and putting on gloves. Hand sanitizers must only be used after you have properly washed your hands. Hand sanitizers can help lower the number of pathogens on your hands. You must not use hand sanitizers to avoid washing your hands. Hand care is an important part of personal hygiene. You need to keep your hands in good condition. To achieve this, keep nails clean and trim; do not wear fake nails; do not wear nail paint or polish; and wear only plain band rings. Glove use is necessary to prevent contamination from food handlers. You must not touch ready-to-eat foods with bare hands. You can also use utensils and wax paper to prevent touching food with bare hands. Gloves must be single use, and you must wash your hands before putting on gloves. Gloves must never be washed, and they must be changed often. Always remove gloves before going to the toilet, before emptying the trash, and when leaving the galley or food prep area. Food handlers must practice good personal cleanliness. This includes taking daily showers, wearing a clean uniform, and wearing hats or hair coverings. Always remove your apron before going to the toilet, going on a break, or leaving the food prep area. Personal food and drinks must not be consumed in the food prep areas. The only time you can eat in the galley is when tasting food. A clean spoon must be used every time for tasting. NOTES: 10 Navigating Food Safety Study Guide

13 Navigating Food Safety CHAPTER 5 INTRODUCTION TO THE FLOW OF FOOD Objectives Describe and prevent cross-contamination Identify and prevent time and temperature abuse Properly use and calibrate thermometers What is cross-contamination? Cross-contamination is the transfer of pathogens to food from a different source. The flow of food is how food moves from the beginning of purchasing the food, storing the food, preparing and cooking the food, to serving the food to people for consumption. During these processes, steps need to be implemented to protect the food from contamination. Food can become contaminated at any point during the flow of food by one or all of the following ways. Other food People Utensils and equipment Facilities Ways to prevent cross-contamination Separate raw and ready-to-eat foods Use separate equipment for each type of food Prepare food in separate areas Clean and sanitize surfaces, equipment, and utensils Practice good personal hygiene Time and temperature abuse refers to leaving food in the Temperature Danger Zone for long periods of time. 41 F 140 F (5 C 60 C) The longer food is allowed to stay in the Temperature Danger Zone, the more pathogens are able to grow on the food. Avoid time and temperature abuse by Cooking food to the proper temperature Navigating Food Safety Study Guide 135 chapter

14 Holding food at the proper temperature Properly cooling and reheating food Preventing time and temperature abuse of food is achieved by limiting the time that food spends in the Temperature Danger Zone. Practices that can help ensure that food remains safe Store Potentially Hazardous Food (PHF) items quickly Prepare small batches of PHF items Use proper procedures w Cooking w Cooling w Defrosting w Reheating It is important to monitor food to ensure that foods are not being time and temperature abused. Monitoring includes Taking temperatures of hot and cold foods Taking temperatures often Record keeping and maintaining logs is a good way to make sure that correct practices are followed and that equipment is working properly. Record-keeping logs must be accurate and up-to-date. When taking temperatures for monitoring and record keeping, there are some different types of thermometers that can be used. Three types Bimetallic Tip sensitive Infrared Bimetallic thermometers are used for taking the temperature of thick foods or large potions. They cannot be used with thin foods. These thermometers must be inserted up to the dimple for accurate reading and calibrated on a daily basis to ensure they are taking accurate temperatures. Tip-sensitive thermometers have a sensing area at the tip and can be used to take the temperature of both thick and thin foods. These thermometers must be available in all areas that work with thin foods. Follow the manufacturer s instructions to calibrate these thermometers. 14 Navigating Food Safety Study Guide

15 Infrared thermometers are good for taking surface temperatures of foods or equipment, but they cannot be used to take internal food temperatures. Do not use infrared thermometers for monitoring food temperatures when cooking, cooling, or reheating foods. Overview - Guidelines for using thermometers Calibrate often Clean and sanitize before using and between different types of food Take temperature from the thickest part of food Take multiple temperatures for each food item Wait for thermometer reading to stop moving NOTES: Navigating Food Safety Study Guide 15

18 Reject meat, fish, or poultry if it doesn t feel right Slimy Sticky Dry Flesh should be firm to the touch and spring back Should not leave an imprint when touched Reject products if they don t smell right Sour smell Smell different than usual Bad smell Fish Reject if there is a strong fishy smell Items must be received at certain temperatures Check temperatures by inserting a thermometer into the thickest part of the food item Hot foods w 140 F (60 C) or above Cold foods w 41 F (5 C) or below Frozen foods w Frozen Shell eggs May be received at 45 F (7 C) or below w Then must be cooled to 41 F (5 C) within 4 hours Milk and dairy products May be received at 45 F (7 C) or below w Then must be cooled to 41 F (5 C) within 4 hours Must be pasteurized Potentially hazardous fruits and vegetables Must be received at 41 F (5 C) or below Cut melons, cut tomatoes, cut leafy greens, etc. 18 Navigating Food Safety Study Guide

19 Shellfish May be received at 45 F (7 C) or below Must be cooled to 41 F (5 C) within 4 hours Must come with labels that have the supplier s information on them Labels must be kept for 90 days from the date the last shellfish (e.g., oysters, clams) was used Storage All storage areas must be Clean Dry In good repair Items being stored Must be covered At least 6 inches (15 cm) off the deck Properly stored and secured to prevent spilling or collapse Approved food grade containers Fully close Leak proof Easy to clean Never use empty chemical containers Storing scoops in food Handle must not touch the food Scoop must not be stored on top of the container Labeling All foods must be labeled with their common names so they may be easily identified Ready-to-eat foods Kept at 41 F (5 C) or lower Must have a 7-day production label Navigating Food Safety Study Guide 19

20 Non-Potentially Hazardous Food (PHF) items do not need a production label If different items are combined, the date for discard would be based on the earliest prepared/opened product First In, First Out (FIFO) Items that are put into storage first are the ones that are used first Items with the earliest use by, sell by, or expiration date are used first Discard any foods that have passed their use by, sell by, or expiration date Storage order in a cold unit (from top to bottom) Cooked and ready-to-eat foods Fish that will be cooked Whole muscle meats Ground meats Whole and ground poultry Dry storage Cool and dry area All products must be stored at least 6 inches (15 cm) off the deck Area must be well ventilated w Control temperature, humidity, and moisture NOTES: 20 Navigating Food Safety Study Guide

21 Navigating Food Safety CHAPTER 7 PREPARING Objectives Demonstrate proper defrosting methods Demonstrate proper preparation practices for specific foods Identify proper cooking temperatures for different foods Demonstrate the proper cooling and reheating practices for different foods The basic guidelines that you must follow when you are preparing food are Clean and sanitize all equipment, surfaces, and utensils Remove only small amounts of food for preparation w Avoid time and temperature abuse Return prepared food to the refrigerator quickly You must never defrost foods by leaving them out at room temperature. Foods must be defrosted using one of the approved methods. Refrigerator w Refrigerator must be kept at 41 F (5 C) or below w Use strainers or racks to prevent water or blood pooling Running water w Water must be 70 F (21 C) or below w Must have permission from the Executive Chef Microwave w Foods must be cooked immediately Fruits and vegetables must be washed and sanitized before being sent to the galley. The sinks that are used to wash fruits and vegetables must be labeled with signs that indicate which one is the wash sink and which one is the sanitize sink. Follow these procedures: Wash, rinse, and sanitize each sink Immerse the items in water and scrub them to remove soil Immerse the items in sanitizer solution at ppm for 10 seconds Fragile fruits like berries should be washed immediately before service to prevent spoilage; do not immerse them in sanitizer solution 7chapter Navigating Food Safety Study Guide 21

22 Pasteurized eggs must be used in foods that are not cooked to the proper temperatures (e.g., Hollandaise sauce). Ice is used for consumption and cooling. After ice is used to help cool foods, the ice must be discarded and cannot be used in food. Ice scoops must also be handled to prevent any contamination. Each scoop must be cleaned and sanitized before being used. You must always store the scoop so the handle does not touch the ice. Foods must be cooked to the required minimum internal cooking temperature to kill pathogens. Different foods require different minimum internal cooking temperatures. Temperatures must be taken during cooking w Take temperatures from the thickest part of the food w Take multiple temperatures The minimum internal cooking temperatures are based on the temperature required to kill the pathogens that are usually found on that food, and they are different for different foods. That is why some foods must be cooked to higher temperatures than others. Minimum internal cooking temperatures 140 F (60 C) for 1 second w Fruits and vegetables that will be held hot for service 145 F (63 C) for 15 seconds w Whole muscle meats Fish Beef steaks Pork chops Lamb chops w Eggs to be served immediately 155 F (68 C) for 15 seconds w Ground meats Beef Pork Fish Game animals w Eggs that will be held hot w Injected meats 22 Navigating Food Safety Study Guide

23 Brined ham Flavor-injected roasts 165 F (74 C) for 15 seconds w Poultry Chicken, duck, turkey Ground or whole w Stuffed meats w Dishes that include previously cooked Potentially Hazardous Food (PHF) items Cooking foods in a microwave Cook to 165 F (74 C) Cover the food Rotate or stir the food halfway through cooking Let the food stand for 2 minutes Take multiple temperatures When foods are cooled, it is important that they pass through the Temperature Danger Zone as quickly as possible. Cooling is a two-stage process w 140 F (60 C) to 70 F (21 C) in 2 hours or less w 70 F (21 C) to 41 F (5 C) in 4 hours or less w Total maximum cooling time of 6 hours If food is prepared at room temperature, and its temperature is below 70 F (21 C) w Cool the food to 41 F (5 C) in 4 hours or less Cooling methods Blast chiller Ice bath Refrigerator Navigating Food Safety Study Guide 23

24 Monitor the temperature of food during the cooling process and record temperatures in the cooling logs. Take and record the beginning temperature Take and record the temperature after 2 hours or less w Make sure the food reaches 70 F (21 C) or lower during these 2 hours After that, take and record the temperature in 4 hours or less w Make sure the food reaches 41 F (5 C) or lower during these 4 additional hours Corrective actions - If food does not reach 70 F (21 C) within 2 hours, or if the food reached 70 F (21 C) within 2 hours, but did not reach 41 F (5 C) within 4 more hours Reheat the food to 165 F (74 C) and cool it again If food prepared at room temperature does not reach 41 F (5 C) within 4 hours It must be discarded If food needs to be reheated, it must reach 165 F (74 C) within 2 hours to ensure that all possible pathogens are destroyed. NOTES: 24 Navigating Food Safety Study Guide

25 Navigating Food Safety CHAPTER 8 SERVING Objectives Explain what is a consumer advisory and what types of foods need one Demonstrate the proper way to hold hot and cold foods on display and during self-service Properly use time control and time control plans Protect food during service and transportation A consumer advisory is a notice that informs passengers about the risk of eating certain foods. They are required whenever an animal product is being served raw or undercooked. This includes foods such as smoked salmon and sushi. An advisory is also required if the operation allows passengers to request menu items be cooked to order. This includes ordering a lamb steak cooked medium rare or ordering eggs undercooked. A consumer advisory must be posted in either of the following ways. Posted at the point of service w Omelet bar, hamburger grill Posted on the menu w An asterisk (*) is placed next to the item and the advisory is printed at the bottom of the menu Potentially Hazardous Foods (PHF) must be held at certain temperatures until they are served to ensure they do not support the growth of pathogens. Hot foods w Held at 140 F (60 C) or higher Cold foods w Held at 41 F (5 C) or lower Temperature must be taken at least every 4 hours w Discard food that is out of temperature range chapter Navigating Food Safety Study Guide 258

26 Food on display must be protected from contamination. The best way to protect food is by using sneeze guards. If food is going to be available for self-service by the passengers, all of the display cases must have self-closing lids. If proper protection is not possible for these situations, the food must be removed from self-service and served to the passengers by a crewmember. Time control means holding food in the Temperature Danger Zone but only doing it for a short period of time. Time control operational standards Food on time control must be discarded after 4 hours or at the end of service, whichever comes first Food cannot be returned to temperature control after it has been on time control Time control starts as soon as the food is removed from temperature control 7-day production labels must be removed when an item is put on time control Operations that are longer than 4 hours w Food must have discard labels Product name Discard time Operations that last less than 4 hours w No discard labels are required When time control is used, a time control plan must be implemented. The time control plan must be Understood by all staff Developed using the standard format w Public Health database Posted in each location where time control is used Rewritten when the operation changes When serving food to passengers No bare hand contact with ready-to-eat foods Use separate utensils for each food item w Clean and sanitize utensils before use w Change utensils often 26 Navigating Food Safety Study Guide

27 Scoops used to serve ice cream and other food items are often kept in dipper wells. Dipper wells must have continuous running water OR If scoops are kept in standing water, the water must be at 140 F (60 C) or higher Food can become contaminated while being served. Staff can contaminate food through improper handling of dishes and flatware, so be sure to follow these guidelines. Hold dishes by the bottom or sides Hold glasses by the stem or outside Hold flatware by the handle Never touch the food contact surface of dishes or flatware. During dining room service, you must make sure the dishes, utensils, and eating areas do not become contaminated. Preset tableware No items may be set out more than 4 hours before the start of service All extra items must be removed once the table is occupied High chair trays and booster seats Cleaned and sanitized after every use Wrapped or covered when stored Food served to a passenger It must not be re-served It must be discarded if not used Buffets Plates and glasses must be stored inverted or protected Flatware at the service station must be stored inverted in cylinders or protected by napkins Crew wrapping flatware must w Wear head coverings w Wear disposable gloves w Practice good personal hygiene Navigating Food Safety Study Guide 27
