1. F.A.T.T.O.M.

2. Bacteria like protein-rich foods.
Meat
Milk
Cheese
Eggs
Fish

3. ACIDITY Microorganisms thrive in a pH range between 6.6 and 7.5.
Bacteria grow best in an environment that is neutral or slightly acidic.
Acidic foods, like vinegar and fresh fruits (especially citrus), seldom provide a favorable climate for pathogenic bacteria.
Most bacteria will not grow at pH levels below 4.6 because the environment is too acidic.
Microorganisms thrive in a pH range between 6.6 and 7.5.

4. Acidity of Certain Foods

5. Time
Food may become dangerous if left out for 2 hours or more after the time it takes to prepare it to be eaten.

6. Temperature Danger zone = 40-140
About room temperature is ideal for bacterial growth

7. Oxygen Most bacteria needs oxygen to grow.
If something needs oxygen to grow this is called Aerobic
If something does NOT need oxygen to grow, this is called Anaerobic
I.E. Botulism does not need oxygen to grow (canned goods) It is rare but deadly.

8. Moisture Bacteria LOVE wet/moist foods!
Not foods such as crackers and breads at room temperature.
Things well preserved with salt and sugar deprive bacteria of water and limit its reproduction.
Examples of this are jams, jellies, and beef jerky.

9. 4 Day = Throw AWAY

10. Vocabulary
Everyone will say the term after Ms. Pilant goes over the pronunciation.
Each person will read a term (or part of a term).
You will need to know these terms/definitions.

8 hours
4 hours
2 hours
6 hours

17. 6. Improperly canned foods could cause which of the following foodborne illnesses?
Bulimia

18. 7. Bacteria wouldn't multiply very fast in a box of corn flakes because
Cereal is low in moisture
The box is too high in the cupboard
Corn flakes are high in protein
Corn flakes are too acidic

19. 8. Is it safe to eat an orange that has been kept at room temperature for more than two hours?
Yes No

20. 9. Beef jerky is shelf stable and safe to eat because
It is low in moisture
It has low water activity
It has been preserved by salt
All of the above

21. 10. A chicken salad sandwich left in the TDZ could have a growth of pathogenic bacteria because
It is a protein-rich food
It has neutral pH
It has a high water activity
All of the above

22. 11. Each of the letters in FATTOM represent a condition necessary for microorganisms to grow and multiply. The letters "O" and "M" stand for which two conditions?
Oxygen and Minerals
Oxygen and Moisture
Oleo and Margarine
Old and Moldy

23. 12. You bring a sack lunch to school, but find out the cafeteria is serving pizza, so you decide to have that instead and leave the lunch in your locker. After school, you open your lunch to eat as a snack. What do you decide to do with the chicken sandwich?
Throw it out because it's been in the TDZ for more than two hours.
Eat it before your mom picks you up so she doesn't get mad.
Microwave it so you can eat it hot.
Share it with your best friend.

24. 13. You bought a hamburger on the way home from school and were about to eat it when a friend stopped by to go to a movie. When you came home four hours later, you noticed it sitting where you left it. You know it's been in the TDZ for more than two hours, but you are pretty hungry. You should
Reheat the burger in the microwave to kill all the bacteria
Throw the burger away because you don't want to get sick
Scrape off the toppings and just eat the beef
Cover the burger and save it for later.

25. 14. Mom bought some steaks at the grocery store, but while unpacking the groceries, she received a phone call. After 20 minutes you notice the meat is still on the counter. You should
Put the meat in the refrigerator to keep the bacteria from multiplying
Tell your mom the steak has been in the Danger Zone too long and ask if you can throw it away
Stop worrying about it because no air can get to the meat through the plastic wrap
turn on the air conditioner and go play a video game
