How likely are you to swallow a Cockroach?

Well, it’s possible to swallow a cockroach but this isn’t something that occurs very frequently. For instance, it can happen while you are sleeping with your mouth open.

Alternatively, there is a possibility that this insect could fly into your mouth when you are close to its nest.

Would You Get Sick if You Swallow a Roach?

Well, if you accidentally swallow those basic cockroaches that are found in homes, then you will most likely get sick. Even though the acid in the stomach usually dilutes the bacteria, sometimes this isn’t effective.

Take a look at this, that if you eat food that’s contaminated by these insects chances are that you might end up feeling unwell. So, if you swallow the insect itself, understand that they carry diseases.

Sickness usually occurs due to the fact that cockroaches usually crawl in dirty areas generally. They walk around in different parts of the house, from the toilet, floor, kitchen counters, to garbage bins.

This way, they usually accumulate different types of bacteria that can trigger allergic or unwanted bacterial infections. Some of the cockroach-borne diseases include:

  • Salmonellosis: it’s caused by the Salmonella bacterium. This disease usually displays its symptoms in humans like food poisoning. Symptoms usually include vomiting, fever, and diarrhea.
  • E.coli infections: it’s a bacterial infection that mainly affects the gut in human beings. E.coli can result in diarrhea and abdominal cramping. Other symptoms may include chills, fever, nausea, and muscle aches among others.
  • Listeriosis: It’s a bacterial infection that can also be caused by roaches. It’s prevalent in people with weakened immune systems. That’s why pregnant women, the elderly, and babies should be cautious when feeding on these bugs. Listeriosis can result in symptoms such as:
  1. Diarrhea
  2. Fever
  3. Muscle aches
  • Asthma: there is a high possibility that roaches can trigger asthmatic episodes. This is because these bugs usually contain specific types of proteins in their bodies that behave as allergens in certain people. When these proteins find their way into asthmatic individuals, they might end up with severe overreaction.

In case you accidentally swallow one of these bugs, monitor yourself very closely. Record any change and if you notice that it’s severe, then immediately contact your doctor
