How Contamination Happens ????
BACTERIA!
The thing that contaminates food most of the time is bacteria. Most bacteria is harmless but in some situations it can cause some serious problems. For bacteria to grow they need 6 essential conditions.
- Food - Like humans, Bacteria need food to survive.
- Acidity - Places with low acidity are a perfect breeding ground for bacteria
- Temperature - Bacteria grows rapidly between 41 and 135 degrees. This is known as the danger zone.
- Time - The longer bacteria is in the danger zone, the more the bacteria grow to unsafe levels.
- Oxygen - Most bacteria need oxygen to grow but this is not always the case.
- Moisture - Bacteria like places with lots of moisture.
You can remember these six conditions by remembering FAT TOM.
FDA'S Prime Suspects
- Salmonella Typhi
- Shigella Spp.
- Enterohemorrhagic and shiga toxin-producing escherihia coli (AKA E-Coli)
Salmonella Typhi
Salmonella lives in humans. People who have had typhoid fever carry this bacteria. Mostly found in poultry. An easy way to prevent this is by cooking food to correct temperature
FOUND IN
Location: Ready to eat foods
SHIGELLA SPP.
This bacteria is found in feces. You can easily get contaminated by eating or drinking contaminated foods Flies are huge carriers of this bacteria.
FOUND IN
Location: TCS foods touched by hand
E-Coli
This bacteria can be found in cow intestines. Can contaminate meat during slaughtering. Purchasing from reliable sources helps reduces the risk of contamination.
FOUND IN
Location: Ground beef and contaminated food
VIRUSES !
FDA'S Prime Suspects
The FDA has identified two viruses that are highly contagious and can cause severe illness.
- Hepatitis A
- Norovirus
Hepatitis A
Location: Shellfish and ready to eat foods
Norovirus
Location: Seafood and RTEF
