Food Safety and Storage
2
Contaminants in food cause over 76 million illnesses and 5,000 deaths in the United States. ◦ Contaminant: is a substance, such as a chemical or organism, that makes food unsafe to eat. ◦ Foodborne Illness: sickness caused by eating food that contains a contaminant. Fever, headache, digestive troubles
3
Most foodborne illness is caused by microorganisms. ◦ Microorganism: is a living thing so small that it can only be seen through a microscope. Bacteria (cause of foodborne illnesses) A few bacteria are dangerous to human health. ◦ Toxin: or poison ◦ Spore: protected cell that develops into a bacterium. Correct Conditions (temperature, etc)
4
Food Safety: keeping food safe to eat by following proper food handling and cooking practices. ◦ Keep yourself and kitchen clean ◦ Do not cross-contaminate ◦ Cook food thoroughly ◦ Refrigerate food properly.
5
Sanitation: prevention of illness through cleanliness. Personal Hygiene ◦ Thoroughly washing your body, face, hands, and avoiding transfer of harmful bacteria. ◦ 20-second scrub: using soap and warm water to scrub your hands (ABC’s). ◦ Clothes, Jewelry, Hair, etc.
6
A Clean Kitchen ◦ Helps limit the growth of bacteria. ◦ Practice these following habits: Wash work surfaces in hot soapy water Wash tops of cans before opening Use clean spoon for taste testing Change dishtowels often Wash laundry and replace with clean linens Keep pets out of the kitchen Pest Control ◦ Insects cause harmful bacteria. Clean up crumbs, food spills, etc.
7
Thorough clean-up is essential for food safety. ◦ Mop up any spills on the floor. ◦ Wash sink ◦ Throw garbage away. Washing Dishes ◦ Scrape and rinse food and place them in one side of sink. (left) ◦ Use sponge or dishcloth to wash dishes in order ◦ Rinse thoroughly ◦ Air Dry on rack
8
Cross Contamination: is the spread of harmful bacteria from one food to another ◦ Most common with: Raw Meat Poultry Seafood Eggs ◦ Wash surfaces often ◦ Use new utensils ◦ Wash hands frequently. ◦ Cutting Boards Use a new one or wash in between cutting different foods
9
Food temperature affects how quickly bacteria grow. The DANGER ZONE is when bacteria grow the fastest. ◦ 40 degrees F to 140 degrees F. ◦ High temperatures during cooking kill most bacteria, but spores and some toxins can survive. ◦ Bacteria grow more slowly when the food is in the refrigerator and freezer; but some bacteria survive freezing. Internal Temperature: the temperature deep inside the thickest part of the food. ◦ Most foods need to reach 160 degrees F.
11
Bacteria can multiply when food is thawing, you should NEVER thaw food at room temperature. ◦ By the time the inside is thawed, millions of bacteria have grown on the outside. Refrigerator (In container) Why? Microwave Skip thawing Cooking time will be longer
12
1. Keep hot foods hot ◦ Higher than 140 degrees F. Warming Tray, etc 2. Keep cold foods cold ◦ Refrigerate until serving time 3. Follow the 2-hour rule ◦ Perishable foods Meats, Poultry, Fish, Eggs, Dairy
13
Identifying Spoiled Food ◦ Dirt, Heat, Moisture ALL promote bacteria growth ◦ Fresh Produce Wilted, Wrinkled, Bruised, Brown ◦ Meats Slimy Texture ◦ Breads, etc Mold ◦ Canned Goods Bulging Cans, Cloudy Fluids ALWAYS THROW AWAY IF YOU THINK IT COULD BE SPOILED!!!!
14
No food can be stored indefinitely. Food has shelf life, the length of time it can be stored and still retain its quality. ◦ Shelf life depends on the type of food, packaging, and storage temperature. To avoid loss of quality, follow these guidelines: ◦ 1. buy only what you need ◦ 2. Look at sell by and use by dates ◦ 3. Clean storage areas regularly
15
Shelf-Stable foods can be stored at normal room temperature; generally below 85 and above 32. ◦ Include: unopened canned goods, dry beans, peas, oils, shortening, grain products. ◦ Storage should be clean, dry without doors to keep out light. ◦ Keep away from household cleaners
16
Bacteria thrive at room temperature, so it is important to put food away promptly. Temperature ◦ Under 40 but above 32 Help air circulate to all the parts of the refrigerator ◦ Do not overload the fridge ◦ Tightly covered Take on taste of other food, spread bacteria Refrigerator Storage: ◦ Dairy, eggs, fresh meat, poultry, and fish ◦ Fresh fruits and vegetables; except onions, potatoes, and sweet potatoes. ◦ Whole grain products, seeds and nuts ◦ Leftover cooked foods ◦ Baked Goods ◦ Any foods that say to refrigerate on the package. Rancidity- or spoilage
17
Freezing allows for long term storage; at temperatures of 0 degrees. Foods that are purchases frozen should be stored promptly in the freezer. Freezing foods can increase shelf life of foods like: bread, meat, baked goods, etc
18
Foods that are purchases already frozen can be stored in their original packaging. Freezer Burn: results when food is improperly packaged or stored in the freezer too long. The food dries out and loses flavor and texture. Packaging material- must be vapor and moisture resistant. ◦ Include: plastic containers, heavy duty plastic freezer bags.
19
When filling storage containers- be sure to leave enough room for the food to expand when frozen. (usually about 1 inch) Label all packages and containers with the contents, amount, date frozen, and any other special instructions. You should keep an inventory of your frozen foods, so you don’t buy food that you already have at home. ◦ Inventory- or up-to-date record
20
When the power goes off or the refrigerator breaks down, the food inside is in danger of spoiling. ◦ In general, avoid opening the door- will help maintain colder temperatures longer. Keeping frozen foods safe ◦ A full freezer will keep frozen for about 2 days. ◦ A half full freezer- about 1 day. ◦ Keep meats separated If they start to thaw their juices may run.
21
Keeping refrigerated foods safe: ◦ During a power outage, food will usually keep in the refrigerator for 4 to 6 hours When the refrigerator is working again: ◦ Discard any fresh meats, poultry, fish, lunch meat, hot dogs, eggs, milk, soft cheeses, and left over's. ◦ Keep butter or margarine if they have not melted ◦ Other foods, including fresh fruits and vegetables are safe if they show no signs of mold, sliminess, or bad odor.
22
Food and Drug Administration (FDA) ◦ Oversee safety of the food supply Food Additives Fat Replacers Hazard Analysis (Food Borne Outbreaks) Irradiation The process of exposing food to the high-intensity energy waves to increase shelf life and kill harmful organisms. Recalls Immediate removal of a product from store shelfs
23
An Agency of the Federal Government that helps to protect the environment. ◦ Monitors the impact of food productions on land, air, and water. ◦ Regulates the use of pesticides ◦ Establishes a tolerance: maximum safe level for food
