fastest. - Between 40 and 140F.
- At room temperature bacteria can double their
numbers every 30 Minutes!
6When Foodborne Illness Strikes!What are the
Symptoms?
- Symptoms vary and many of them are similar to

14Shop Safely Store Food Right!
15Food Safety When You Shop
- Look at the dates on packages that tell you about
a foods freshness. - Choose canned goods that are free of dents,
bulges, rust, or leaks. - Place raw meat, poultry, and fish in plastic bags
to keep their juices from dripping on other foods
in the cart. - Make sure food packages dont have holes, tears,
open corners, or broken safety seals.
16Food Safety When You Shop (contd)
- Check that refrigerated foods feel cold and
frozen foods feel solid. Avoid frozen foods with
ice crystals or discoloration they may have been
thawed, and refrozen. - Plan your shopping so that you select
refrigerated foods , frozen foods, and hot items
from the deli last. That way theyre at room
temperature for a short time. - After you shop take the food home right away and
store it properly. If it will take longer than 30
minutes to get home, bring an insulated cooler
for perishable foods.
17Storing Food
- To keep foods safe and fresh at home, you must
know how to store it! - There are 3 basic food storage areas
- Dry Storage
- Refrigerator Storage
- Freezer Storage
18Dry Storage
- What it Means
- A cabinet or other area thats clean, dry, dark,
and cool (below 85F). - Dont store foods under the sink or in cabinets
next to heat-producing appliances (including the
refrigerator). - Dont store household cleaning products or trash
in the same cabinet as food.
19Dry Storage
- What to Store Here
- Canned Goods
- Cereals
- Crackers
- Pasta
- Dry Beans
- Baking Mixes
- Vegetable Oil
- Peanut Butter
- Make sure to check the label for foods that need
to be refrigerated after opening.
20Dry Storage
- Storage Tips
- Rotate canned and packaged goods by putting new
purchases in the back behind older ones. - This will help you remember to use the older
items first.
21Refrigerator Storage
- Proper Temperatures
- Between 32 and 40F.
- Use a refrigerator thermometer to check.
- What to Store Here
- Perishables such as meat, poultry, fish, dairy
foods, eggs, fresh fruits and vegetables, and
leftovers. - Check package labels for foods that need
refrigeration after opening.
22Refrigerator Storage
- Storage Tips
- To keep foods from drying out, use foil, plastic
wrap, plastic bags or airtight containers. This
will also keep odors from transferring to other
foods. - Leave space between foods to allow room for cold
air to circulate. - Wipe up spills immediately and remove spoiled
foods. - Use door shelves for foods that arent highly
perishable, such as condiments. Interior doors
and shelves stay colder than door shelves.
23Freezer Storage
- Proper Temperatures
- 0F or less.
- Check with a freezer thermometer.
- What to Store Here
- Food purchased frozen, as well as foods that can
be frozen for longer storage. This includes
meat, poultry, fish, breads, and home-prepared
foods such as casseroles.
24Freezer Storage
- Storage Tips
- Store foods purchased frozen in their original
packages. - Wrap other foods properly to avoid freezer burn-
changes in color, flavor, and texture that result
when food loses moisture in the freezer. - Food with freezer burn has areas that look white
and dried up. It Isnt harmful, but its not
appealing either. - Use freezer paper, heavy-duty foil, plastic
freezer bags, and airtight containers. - Label foods you freeze yourself with the name of
the food, date frozen, and number of servings. - Rotate foods as you store them, putting oldest
foods toward the front.
25When Food Spoils
- Never taste foods that you suspect are spoiled.
- Some foods will
- Loose nutrients
- Go stale
- Wilt
- Grow microorganisms
26Discard Without Tasting
- Canned goods that leak, bulge, have a foul odor,
or are badly dented. - Jars that are cracked or have loose or bulging
lids. - Any container that spurts liquid when you open
it. - Food that is slimy, mushy, discolored, or just
doesnt look or smell right. - Moldy foods- in most case (see next slide).
- Leftovers that have been in the refrigerator more
than 4 days- and the mystery foods that are
who-knows-how-old! - Any food your not sure of- When in doubt throw it
out!
27Dealing With Mold
- On hard cheeses- such as cheddar- you can safely
cut away small areas of mold. Cut at least 1
inch around the moldy area. Put the remaining
cheese in a fresh wrapper or container. - Discard all other foods that are moldy.
- Mold gives off invisible spores- thats how it
spreads. Wrap moldy food well before you throw
it out. Check other foods for mold too. Clean the
container and refrigerator well.
28Keep it Clean!
29Keeping Things Clean
- From the supermarket to your table, one way to
prevent foodborne illness is by following rule of
sanitation. - Sanitation preventing illness through

or other symptoms of illness. - Before you begin to prepare food, tie back long
hair. - Wear clean clothing. An apron will help protect
you against spills and spatters. - Cover any cuts or sores on your hands with a
clean waterproof bandage- or wear clean plastic
rubber kitchen gloves. - Wash gloved hands as often as bare hands.

out- on a regular basis. Use hot soapy water, a
disinfectant cleaner, or a mixture of bleach and
water. - Keep the kitchen clean as you work, wiping up
spills right away. - Consider using paper towels to clean kitchen
surfaces. If you use cloth towels or sponges,
rinse them well between uses. Wash them often in
the hot cycle of the washing machine.
34The Clean Routine (contd)
- Always use clean utensils and dishes.
- Keep dirty dishes away from food preparation
areas. - Wash dishes promptly.
- Wipe the tops of canned foods before opening
them. - Clean the blade of the can opener after each use.
35Avoiding Cross-Contamination
- Cross-Contamination occurs when harmful bacteria
are transferred from one food to another. - Keep raw meat, poultry, fish, and their juices
away from ready-to-eat foods in your shopping
cart, grocery bags, refrigerator, and while
preparing foods. - Use one cutting board for meat, poultry, and fish
and another for other foods. - Use plastic or other non-porous cutting boards.
36Avoiding Cross-Contamination
- Make sure cutting boards are free from cracks and
crevices- these are perfect hiding places for
bacteria. - Wash everything that comes in contact with raw
meat, poultry, and fish in hot soapy water
immediately. This includes utensils, cutting
boards, dishes, the counter, and your hands. - Never place cooked or ready-to-eat foods on an
unwashed plate or cutting board that previously
held raw products.
37Controlling Temperatures
38Thawing Foods Safely
- Some frozen foods require thawing before cooking.
- If these foods are allowed to thaw at room
temperature, the outer surface may reach the
danger zone. - Bacteria on the surface can grow while the center
of the food is still thawing. - Methods for thawing frozen foods include
- In the refrigerator
- In cold water
- In the microwave oven
39Thawing in the Refrigerator
- Place frozen foods on the lowest shelf in a
plastic bag to collect any juices. - This takes planning- many frozen foods take a
full day or longer to thaw in the refrigerator.
40Thawing in Cold Water
- Faster than refrigerator thawing, but requires
more attention. - Place the frozen item in a sink or large bowl
filled with cold water. - Be sure the food is wrapped in a leak-proof
package or plastic bag. - Change the water frequently to make sure it stays
cold.
41Thawing in the Microwave Oven
- Place frozen item in a microwave-safe container
and defrost on the low or defrost setting.
Check your owners manual for specific
instructions. - Cook food right away- some areas of the food may
begin to cook during microwave thawing and its
not safe to cook food only partially.
42Cooking Food Thoroughly
- Foods are properly cooked when they are heated
for a long enough time and at a high enough
temperature to destroy harmful bacteria. - Always cook food thoroughly, and finish cooking
once you start. - Dont try to roast your turkey for ½ the cooking
time today and the rest tomorrow- that wont do
the job.
43Cooking Food Thoroughly
- The best way to determine if food is cooked
thoroughly is by measuring the internal
temperature with a clean meat thermometer. - Color and texture changes are not always reliable
signs.
