Some of the symptoms include fever, headaches, muscle aches, and general malaise, and can even become more severe and ultimately lead to a more serious form of the disease.

It is not recommended to eat food containing dust, because according to the Pan American Health Organization, this component can be contaminated with microorganisms that are responsible for diseases. For example, the bacteria Bacillus cereus can cause diarrhea, abdominal cramps, and even vomiting when found in humans.
3. Insects like cockroaches can use the cans to deposit their eggs or feces.
According to the World Health Organization, these bugs are common spreaders of diseases like dysentery, gastroenteritis, diarrhea, typhoid, gangrene, and leprosy. And the best way to avoid these is to wash cans with soap and water before opening them.

In addition, some insects, like flies, are transmitters of more than 60 diseases, including typhoid, cholera, and polio. You probably don’t want any of those in your food!
