Diseases Humans Can Get By Eating Foods Contaminated By House Rats

Although generally perceived to be a nuisance, the presence of house rats can pose a major health risk to humans in many ways, and they are especially dangerous when they contaminate food sources. House rats are known to carry salmonella, toxoplasmosis, tapeworms, and other potentially harmful parasites and bacteria that can cause illnesses in humans. According to Centers for Disease Control and Prevention, Eating food contaminated with house rat droppings, saliva, or urine can lead to health complications, especially for those with weaker immune systems, such as young children and the elderly.


Salmonella is a bacterium that can cause a range of digestive issues, including diarrhea, fever, and abdominal cramps. These symptoms usually begin within 48 hours of consuming contaminated foods, and can last for 4-7 days. Salmonella infections can be easily spread from house rats to humans, and many cases of salmonella contamination have been attributed to rat droppings in contaminated foods.

Infected house rats may shed large amounts of the bacteria through their urine or feces, and long-tailed rodents have been known to spread even greater amounts of bacteria via airborne particles. Eating food that is contaminated with rat droppings, urine, or saliva can lead to infection in humans.


Toxoplasmosis is a parasitic infection that humans contract by consuming contaminated foods, including those contaminated by house rats. Symptoms of toxoplasmosis can range from mild to severe, and may include swollen lymph nodes, brain damage, fever, and fatigue.

Toxoplasma gondii, the parasite that causes toxoplasmosis, is spread through the urine and feces of contaminated animals, such as house rats. Eating food that is contaminated with rat droppings can lead to infection in humans. The risk is especially high for immunocompromised individuals, such as young children and the elderly.


House rats can carry tapeworms, which can pose a serious health risk for humans if consumed by way of contaminated food. Tapeworms can infect the human intestines, and symptoms can range from mild to severe. Common symptoms of infection may include abdominal pain, diarrhea, and fatigue.

Infection occurs when humans consume food that has been contaminated by infected house rats with tapeworms in their digestive systems. The eggs contained within these tapeworms can survive in soil and on plants, and may be spread to food sources through contact with rat droppings or saliva. As a result, eating foods contaminated by house rats can lead to the transmission of parasitic worms in humans.


Trichinosis is an infection caused by consuming meat that has been contaminated by larvae from a type of roundworm known as Trichinella. These larvae are generally found in wild animals, and can also be found in house rats. Infected house rats may spread these larvae to other food sources, as can contact with their droppings or saliva.

When a human eats contaminated food, these larvae will enter their intestines and begin to mature into adult worms. Common symptoms of trichinosis include fever, muscle pain, swelling in the face, and abdominal pain. The longer these worms remain in the digestive system, the greater the chance of infection. To prevent the spread of trichinosis, it is essential to avoid eating food that may have been contaminated by house rats or other wild animals.


Leptospirosis is an infectious disease that is spread through the urine and other bodily fluids of infected animals. House rats are one such animal, and consuming food contaminated with their urine or saliva can lead to infection in humans. Common symptoms of leptospirosis can include fever, jaundice, and muscle pain. Left untreated, the disease can cause potentially fatal complications.

In conclusion, it is clear that house rats can be a source of serious health risks for humans. Eating food contaminated with their droppings, urine, or saliva can lead to infections, such as salmonella, toxoplasmosis, tapeworms, trichinosis, and leptospirosis. Individuals with weaker immune systems, such as young children and the elderly, are especially vulnerable to the effects of these diseases. To prevent the spread of these illnesses, it is essential to keep house rats away from food sources, to store food properly, and to properly dispose of food waste.
