what bacteria need to grow
Food, Acidity (4.6 to 7.5), Temperature (41 to 135... danger is 70 to 125), Time, Oxygen, Moisture
major bacteria include:
-bacillus cereus-listeria monocytogenes-shiga producing e.coli-campylobacter jejuni-clostridium perfringens-clostridium botulinum-nontyphoidal salmonella-salmonella typhi-shigella spp.-staphylococcus aureus-vibrio vulnificus-vibrio parahaemolyticus

-bacillus cereus-listeria monocytogenes-shiga producing e.coli-campylobacter jejune-clostridium perfringens-clostridium botulinum
Bacillus Cereus
-can cause two diff. diseases:1. Diarrhea illness, bacillus cereus gastroenteritis--cooked vegetables, meat, milk2. Vomiting illness, bacillus cereus gastroenteritis--rice, fried rice, rice pudding'-CONTROL TIME AND TEMPERATURE

-botulism-incorrectly canned food, reduced oxygen packaged good, temperature abused vegetables like baked potatoes-untreated garlic and oil mixtures-double vision, difficulty speaking and swallowing-CONTROL TIME AND TEMP
