Health Risks of Cockroach Infestation: Allergies, Diseases, and More

As dreadful pests, cockroaches live up to their names as they pose significant health risks to humans. Their presence in homes can lead to allergic reactions, trigger asthma symptoms, and facilitate the spread of various diseases. Understanding the health hazards posed by cockroaches can help you take proactive steps to prevent infestations and protect your well-being.

Allergic Reactions are the Most Common

One of the most immediate and common health risks associated with cockroach infestations is the development of allergic reactions. Cockroach allergens come from their saliva, droppings, and shed body parts, which can accumulate in household dust over time. When inhaled, these allergens can cause allergic reactions in sensitive individuals.

Symptoms of cockroach allergens include sneezing, runny nose, watery eyes and skin rashes. Children and individuals with weakened immune systems are particularly susceptible to these reactions.

Cockroaches are carriers of Various Diseases

Cockroaches are notorious for their ability to spread diseases. As scavengers, they feed on garbage, decaying matter, and even feces, picking up bacteria and pathogens along the way. When they crawl over food, kitchen surfaces, and utensils, they can transfer these harmful microorganisms to humans, potentially leading to illness.

Some of the most common diseases carried by cockroaches include:

Salmonella

Salmonella is known for causing food-borne illnesses. Symptoms include diarrhea, fever, and abdominal cramps. When cockroaches eat contaminated food or waste, they can carry salmonella on their bodies and transmit the bacteria to human kitchen surfaces. Similarly, serious diseases like gastrointestinal illness can also ensue if food prepared from cockroach infested areas are consumed — especially in the case of children poisoned by other elements such as petroleum fume or with a weakened immune system.

E. Coli

Another bacteria carried by cockroaches is Escherichia coli (E. coli). E. coli also can be very dangerous causing serious infections, especially in the gastrointestinal system (with symptoms like stomach cramps and sometimes bloody stool as well as nausea/vomiting) just like Salmonella. If cockroaches are in your home, they may transmit E. coli through that food or surface contact as well.

Dysentery

Dysentery is a severe intestinal infection that can lead to diarrhea, abdominal pain, and dehydration. It is caused by bacteria and amoebas that cockroaches can carry after coming into contact with human waste. Consuming contaminated food or water can lead to this potentially dangerous infection, especially in regions with poor sanitation.

Cholera

Cholera is a bacterial infection that leads to severe diarrhea and dehydration, and it can be fatal if left untreated. Although more common in areas with inadequate access to clean water and sanitation, cockroaches can play a role in spreading cholera by contaminating food and water with the bacteria.

Typhoid Fever

Typhoid fever is a serious illness caused by the bacterium Salmonella typhi, which is spread through contaminated food and water. Cockroaches can act as carriers of this bacterium, transferring it to food items in the home. Symptoms of typhoid fever include high fever, weakness, stomach pain, and loss of appetite.
