and vacuum-sealed foods including canned vegetables
✔✔Clostridium botulinum - Infection - ✔✔onset 4-6 hours, targets the nervous system
and may cause permanent damage if not treated immediately
✔✔Clostridium botulinum - Symptoms - ✔✔Botulism, neurotoxicity - double vision,
inability to swallow, speech difficulty, progressive paralysis of respiratory system, can be
fatal
✔✔Clostridium botulinum - Prevention - ✔✔canned and packaged items are in good
condition upon receipt, even small dents can be potentially dangerous (best to return to
vendor)
✔✔Food spoilage is caused by - ✔✔rough handling, exaggerated high or ow keeping
temps, bacteria, enzymes, mold and pests
✔✔Dehydration and Overheating can be used to reduce - ✔✔pathogenic biological
contaminants
✔✔Vegetables regularly covered in soil, like potatoes and mushrooms, should be stored
- ✔✔below or beneath other veggies so that any loose soil will not fall on clean items
✔✔TCS foods include (9 categories) - ✔✔Time/Temp Control for Safety: 1) raw and
most cooked meat, poultry and seafood; 2) most milk and dairy products; 3) eggs; 4)
cooked veggies and pasta; 5) raw seed sprouts and soy products; 6) cut melons; 7) cut
leafy greens; 8) garlic in oil that have not been processed; 9) cut tomatoes
✔✔Conditions that cause disease causing bacteria to multiply include (5) - ✔✔1) Foods
high in protein, moist and slightly acidic PH; 2) Time; 3) Temp in the danger zone 41 to
135 degrees F; 4) Oxygen; 5) Moisture
✔✔Bacteria only need _____ amount of time in the danger zone to multiply - ✔✔10-20
mins
✔✔The danger zone temperature is between - ✔✔41 and 135 degrees F
, ✔✔Cooking at high enough temps with kill most bacteria BUT - ✔✔does not destroy all
dangers of toxins; contamination can occur after cooking
✔✔What moisture rating do bacteria need to become pathogenic? - ✔✔above 0.85 AW
✔✔Top Food Allergens include (8): - ✔✔Peanuts, Soybeans, Milk, Eggs, Fish, Shellfish,
Tree nuts, Wheat
✔✔Does Cold Preservation kill bacteria? - ✔✔No, it only slows the growth. Refrigeration
temps must be 34-40 degrees F for short term storage
✔✔What are types of Heat Preservation? - ✔✔Pasteurization , Ultra Heat Treatment
(UHT), Sterilization & Canning
✔✔What is Pasteurization? - ✔✔A type of heat preservation, which heats food to mild
temps and cools immediately, that still requires refrigeration afterwards. Commonly for
dairy products, eggs and wine.
✔✔What is Ultra Heat Treatment (UHT)? - ✔✔a type of heat preservation like
pasteurization but uses higher temps
✔✔What is Sterilization & Canning? - ✔✔a type of heat preservation, which heats foods
at high temps for a long enough time to destroy all organisms and foods often lose
quality - canned foods
✔✔High Risk foods include: - ✔✔protein rich, moist and at room temperature; "Ready-
to-Eat" foods
✔✔Frozen foods enter the danger zone when - ✔✔Thawing - ice crystals may remain in
the center of large foods not thawed properly
✔✔When is it unsafe to thaw frozen foods? - ✔✔At room temperature
✔✔You may only microwave foods to thaw safely if - ✔✔foods are cooked immediately
afterwards
✔✔You may thaw foods in the refrigerator at what temperature? - ✔✔colder than 41
degrees F
✔✔How can you thaw food using running water? - ✔✔Submerged under running water
at or below 70 degrees F
