Can Cockroaches Be Harmful to Humans?

Cockroaches can be harmful to humans for two reasons: they can transmit disease by contaminating food, surfaces, and water, and they can also transmit diseases through their feces. They are also known to carry bacteria, including E. coli O157:H7, which can cause serious food poisoning. In most cases, the symptoms of E. coli poisoning last about three weeks and require little medical help. However, cockroaches can also carry serious bacteria, such as Staphylococcus aureus, which can cause serious infections. These bacteria can be spread through the air, and they can affect the heart and blood vessels.

The presence of cockroaches in a home or business is a problem for many people. Infestations of these insects can affect the health of employees and customers, and can even lead to allergic asthma. According to the World Health Organization, cockroaches are known carriers of a range of bacteria and fungi, including salmonella, cholera, and dysentery. They may also cause typhoid fever and plague, which are both dangerous to humans.

In addition to carrying bacteria, roaches are also known to be carriers of multidrug-resistant bacteria (MRSA). They can be transferred to humans through food and water. These bacteria are also known to cause asthma and allergic reactions, and can even cause anaphylactic shock.
