How do you contaminate food?

Answer 1

Animals Many foodborne microbes are present in healthy animals (usually in their intestines) raised for food. Meat and poultry can become contaminated during slaughter by contact with small amounts of intestinal contents. Fresh fruits and vegetables can be contaminated if washed or irrigated with water contaminated by animal manure or human sewage. Food Handling During food processing, foodborne microbes can be introduced by infected humans handling the food or by cross contamination with other raw agricultural products. For example, Shigella (bacterium) and Norwalk virus (Norovirus) can be introduced by an infected food handler's unwashed hands. Food Preparation In the kitchen, microbes can be transferred from one food to the other by using the same knife, cutting board, or other utensil without washing in between. Fully cooked foods can become re-contaminated if they touch other raw foods that contain pathogens. Food StorageMany bacterial microbes need to multiply to larger numbers in food in order to cause disease. Under warm and moist conditions, for instance, slightly contaminated food left out overnight can become highly infectious as bacterial microbes multiply. Prompt refrigeration or freezing prevents most bacteria on food from multiplying. High salt, sugar, or acid levels also keep bacteria from growing. Heating Food Microbes are killed by heat. If food is heated to an internal temperature above 160F (78C), even for a few seconds, this is enough to kill most bacteria, viruses, or parasites. Toxins produced by bacteria vary in their sensitivity to heat. For instance, the toxin that causes botulism is inactivated by boiling, whereas the staphylococcal toxin is not.

The most likely way is by not washing your hands thoroughly before handling food. The worst way some people contaminate food is by not washing their hands after using the lavatory, particularly after producing a number two in the lavatory and after wiping their behind with toilet paper and then after leaving lavatory handling the food with their same hands used to wipe their behind. This can make whoever eats that food very ill. So can not washing your hands after urinating.

Food may also get contaminated by vermin, especially in very hot humid weather, if insects like flies land on it, particularly if those same flies have previously landed on human or animal excreta. Other insects like cockroaches can also contaminate food if ever allowed to climb on to it. Another serious way you can contaminate food is if you allow rats to get anywhere near where it is lying or where it is stored.

Some types of meat, particularly chicken, can be contaminated if not cooked properly before eating so causing somebody to get salmonella poisoning. Double freezing is another way of contaminating food. If something is deep frozen in the fridge and taken out to prepare for eating but then after it has thawed, you make the mistake of putting some of it back in the deep-freeze again for future use, the next time you take it out it could be contaminated and whoever eats it could get ill.

Answer 3

Meat can be contaminated very easily. If too many germs are able too reach the meat, it really can become contaminated if left too long out or somewhere where germs can reach it. My advise is too keep meat refrigerated when not in use and covered up. Make sure that when it is in the fridge, it's away from other food, as that food could be contaminated and the germs could build up on the piece or section of meat.

Answer 4

rat poisoning! or if its like old and gross and moldy

Answer 5

When you purchase food, for the most part you can be confident it is not contaminated. However, it may become contaminated through improper handling and storage at the house.
