Leafy greens may become contaminated on the farm through contact with wildlife, feces, or unclean water, or due to poor hygiene during harvesting by farmers. This can lead to the proliferation of bacteria, and washing them after harvesting does not guarantee they are safe to eat.
1. Leafy Vegetables
Ranked as the number one vegetable category, this includes lettuce, which is commonly eaten in the West. The primary reason it is dangerous is that it is not properly washed. Vegetables are often eaten by Westerners in salads like lettuce salad. If not cleaned thoroughly, vegetables can easily become contaminated with this E. coli.

2. Eggs
Salmonella in eggs can survive in the intestines of animals and be transmitted to the eggs via feces. Certain types of Salmonella can infect a hen's ovary, causing the egg to be contaminated before the shell is formed.
3. Tuna
Symptoms from tuna are typically scombroid poisoning. Tuna spoils rapidly after being caught. If stored at temperatures above 15.6°C (60°F), it releases a natural toxin. This toxin cannot be destroyed by cooking, refrigerating, smoking, curing, or canning.
4. Potatoes
Potatoes are usually cooked and do not contain bacteria, but potato dishes often have many ingredients, some of which may be problematic. The most common is Salmonella, followed by E. coli.
5. Cheese
Certain Latin American-style cheeses may be made with unpasteurized milk. Soft cheeses may contain Listeria, which pregnant women must be cautious of, as it can cause miscarriage.
6. Ice Cream
Soft ice cream also contains Listeria. This bacterium can survive on metal surfaces, remaining in ice cream machines and contaminating large quantities of ice cream.
7. Tomatoes
Tomatoes are typically the cause of Salmonella-related illnesses. The bacteria enter the tomato through the roots or the blossom, so tomatoes should not be eaten raw.
8. Sprouts
The seeds of sprouts may become contaminated during growing or storage. The warm and humid environment required for their growth easily leads to a large proliferation of bacteria.
9. Blackberries
Berry fruits containing Cyclospora can parasitize the intestines, causing severe diarrhea, dehydration, and stomach cramps. Patients must receive antibiotic injections and therefore need to see a doctor.
