What Rats Are Poisonous to Humans
WouterThe poisonous properties of some species of rats have long been suspected by people, particularly in East Africa. However, there is still little known about the exact mechanism of how these animals get their poison. It’s not completely clear, but scientists believe that the poisons are released from the specialized hairs on their flanks. Some rat species have even been found to be highly toxic to humans.
Rat poison can cause gastrointestinal problems. In some cases, it can lead to intestinal bleeding and organ failure. In severe cases, people may even be hospitalized. In addition, rats may transmit diseases that affect humans, such as leptospirosis, which is caused by bacterial infection. Most people who become infected will have only minor symptoms, although one in ten infections may cause kidney damage, liver failure, and even death.
A rat’s bite can also cause a severe infection, called rat bite fever. This illness can be transmitted to humans through the bite of a rat or by touching contaminated food or water. The symptoms of rat-bite fever can include abdominal cramps, fever, and nausea and vomiting. The infection can also cause skin rashes, headaches, and muscle pain.
Because rats are nocturnal and are adept at hiding, they can exist in large numbers without attracting attention. As such, they are often found in homes where humans are not around. As a result, rats can be a major nuisance and pose a significant health risk.
