How does food get contaminated?
Food can get contaminated at any time from harvesting, processing, shipping or even when it is being prepared. Cross contamination which is the transfer of harmful bacteria from one surface to the other is quite often the cause. The popular belief that food cooked at home cannot cause food poisoning is erroneous. If not washed or prepared well, even home cooked food can be harmful.
Tips to prevent food poisoning

Make sure that canned food is well within its expiry date
Keep raw food and canned food separate
Refrigerate food if you plan to eat it later
Make sure food is fully thawed when reheating
Pick good restaurants when you eat out
Don’t eat food from road side carts
Carry water with you when you go out
Make sure that the food prepared at home is cooked well
Foods that can cause food poisoning

Raw or undercooked eggs
Canned food that have not been packaged well
