What happens if you eat a cockroach in your food?

Quick Answer

Eating a cockroach that has accidentally ended up in your food is generally not harmful, although it can be quite disgusting and disturbing. While cockroaches can carry bacteria and spread disease indirectly, the occasional ingestion of a cockroach is unlikely to cause illness. However, if you eat food infested with cockroaches or their waste, you may be exposed to larger amounts of bacteria and have a higher risk of getting sick. The most common health issues linked to cockroaches are food poisoning and allergies. Other potential risks include exposure to pesticides and toxic substances. Overall, the health effects depend on the amount and frequency of cockroach consumption. An isolated incident is not a major cause for concern.

What Are Cockroaches?

Cockroaches are common household pests found throughout the world. There are over 4,000 different species, but the most prevalent cockroaches that infest homes are:

  • German cockroaches
  • American cockroaches
  • Oriental cockroaches
  • Brown-banded cockroaches

Cockroaches prefer warm environments with access to food and water. They are most active at night and can spread quickly once established in a home. Cockroaches are known for being resilient and able to survive for long periods without food or water. They are difficult to fully eliminate once an infestation occurs.

Do Cockroaches Carry Diseases?

Cockroaches are potential vectors of disease. This means they can pick up germs elsewhere and transport them via their legs, body, and feces. Cockroaches walk through sewers, garbage, and other unsanitary places, allowing them to acquire bacteria such as Salmonella and E. coli. Although cockroaches do not directly cause illness, they can spread germs by contaminating food, surfaces, dishes, and utensils.

Some key facts about diseases and cockroaches:

  • Cockroaches can transmit up to 33 types of bacteria
  • Cockroach feces and body parts contain allergens that can trigger asthma
  • Cockroaches may spread pathogens that cause dysentery, cholera, leprosy, the plague, and typhoid fever
  • Antibiotic-resistant bacterial strains can be carried by cockroaches

While cockroaches have the potential to spread germs, the risk of actually contracting an illness from a cockroach is quite low in most Western countries. Proper sanitation practices help reduce disease transmission.

What Happens If You Eat a Cockroach?

If you accidentally eat a cockroach or other insect parts that have contaminated your food, you may have concerns about getting sick. Here is a look at the most likely health outcomes:

Food Poisoning

Consuming a cockroach can expose you to bacteria that cause foodborne illnesses. Cockroaches carry germs such as Salmonella, E. coli, and Shigella in their guts and on their body surfaces. These bacteria can be transmitted to foods and surfaces if cockroaches crawl on it or defecate on it.

Eating the cockroach puts the bacteria directly into your digestive system. Typical symptoms of food poisoning include nausea, vomiting, abdominal cramping, and diarrhea. Most healthy people will recover within 24-48 hours without treatment. Those at higher risk of complications include infants, the elderly, pregnant women, and those with weakened immune systems.

Allergic Reaction

Some individuals may be allergic to cockroach parts and droppings. Ingesting cockroach matter can trigger an allergic reaction ranging from mild symptoms like itchy skin or a stuffy nose to severe reactions like difficulty breathing. People with asthma are especially susceptible to cockroach allergies triggering breathing problems.

An allergic response is more likely to happen from repeated exposure over time but could potentially occur from eating a single cockroach. Seek medical care if you experience any signs of a severe reaction after consumption.

Choking Hazard

While rare, it is possible to choke on a cockroach if accidentally swallowed whole. Cockroaches have hard wings, legs, antennae, and an overall large, unsavory body that could potentially obstruct breathing passages if lodged in the throat. Choking poses the highest risk to young children who are more likely to put items in their mouths.

If a live cockroach was ingested, the choking hazard is reduced once the insect dies, allowing it to be more easily broken down. Do not try to manually remove an object from someone’s throat yourself due to risk of injury. Seek emergency medical help if choking occurs.

Digestive Disturbances

Beyond foodborne illness and allergies, some individuals may experience other temporary gastrointestinal distress from eating cockroaches. The human digestive system is generally equipped to break down and excrete the shell and body parts with no lasting issues.

However, symptoms like nausea, stomach pain, cramps, vomiting, and diarrhea could result as the body tries to quickly flush out the disturbing invader. These symptoms typically resolve in a day or two. If severe or prolonged, see a doctor to rule out other potential medical issues.

Pesticide Exposure

Cockroaches residing in a home may have ingested or come into contact with pesticide residues used to control infestations. Eating a contaminated cockroach could transfer these toxic chemicals into your system. Possible pesticides include boric acid, gel baits, growth regulators, and neurotoxic agents.

Acute pesticide poisoning can lead to headaches, nausea, vomiting, diarrhea, breathing issues, impaired coordination, and other neurological symptoms. The extent of poisoning depends on the type and amount of pesticide as well as the individual’s sensitivity.

Long-term health consequences linked to repeated low-level pesticide exposure are still being investigated but may include cancer, reproductive issues, and cognitive impairment.

Psychological Effects

In addition to potential physical health impacts, accidentally eating a cockroach can take a psychological toll. Many people find cockroaches disgusting and disturbing. Eating one can provoke immense disgust, anxiety, stress, nausea, and persistent fears about parasites or illnesses.

The extreme revulsion around consuming cockroaches can even lead to exaggerated physical reactions like gagging, vomiting, or loss of appetite stemming from the emotional turmoil rather than toxicity. Psychological counseling may help some individuals overcome trauma related to ingesting cockroaches or other innately disturbing substances.

Risk Factors

Certain individuals and situations carry higher risks associated with accidentally eating cockroaches.

High-Risk Groups

  • Young children
  • Elderly
  • Pregnant women
  • Those with weakened immune systems
  • People with allergies/asthma

These groups are more vulnerable to food poisoning, allergic reactions, pesticide impacts, and other health effects. Children also have a higher risk of choking.

Heavy Infestations

Eating food contaminated by just one cockroach carries a relatively low risk. However, consuming food infested with cockroach parts, eggs, or feces raises concerns due to a higher pathogenic load. Heavily spoiled food also has more time to foster bacterial growth.

Frequent Exposure

Isolated cockroach ingestion incidents have minimal health effects for most people. But repeated exposure to cockroaches and their waste may increase the odds of eventually contracting a foodborne illness or having an allergic response.

Improper Food Handling

Eating cockroach-contaminated food poses more risk if the food was not stored, prepared, or cooked properly. Cockroach waste is more likely to transmit illnesses when left on foods that are consumed raw, unwashed, or undercooked.

What to Do If You Eat a Cockroach

Despite the yuck factor, try to stay calm if you realize you’ve accidentally eaten part of a cockroach. Here are tips for responding:

  • Drink water to help flush out any potential contaminants
  • Contact your doctor if concerning symptoms develop or persist beyond 24-48 hours
  • Save the food remnants containing the insect parts in case testing is needed
  • Inspect the food package thoroughly for signs of infestation
  • Report the issue to the grocery store, restaurant, or manufacturer
  • Practice relaxation techniques to overcome immediate disgust and stress
  • Limit consumption of cockroach contaminated food even if it looks otherwise normal

Getting sick from eating a single cockroach is uncommon. But take sensible precautions and see a medical provider if you have ongoing vomiting, diarrhea, allergic reactions, or other severe symptoms.

Prevention Tips

You can take proactive steps to avoid accidentally eating cockroaches:

  • Inspect food packages before purchase and consume before expiration dates
  • Rinse fruits and vegetables thoroughly
  • Keep kitchen surfaces and appliances clean
  • Store opened dry foods in sealed containers
  • Clean up spills and crumbs that can attract roaches
  • Cover trash cans securely
  • Don’t leave pet food out overnight
  • Fix plumbing leaks that provide water sources
  • Inspect for signs of cockroaches like droppings and egg casings
  • Use roach traps, gels, baits or make DIY traps for control
  • Seal cracks and crevices where roaches enter
  • Call an exterminator for severe infestations

Proper food handling and kitchen hygiene day-to-day make it less likely that cockroaches will contaminate anything you eat. But occasional encounters may still occur. Stay vigilant but don’t panic if you happen to eat a cockroach – just take sensible health precautions afterwards.


Accidentally consuming a cockroach can be disturbing and elicit concerns about getting sick. However, a one-time or isolated occurrence is unlikely to cause major health issues for most people. While cockroaches can transmit bacteria and parasites, proper cooking and digestion typically neutralize any contaminants.

Potential risks from eating cockroaches include food poisoning, allergies, choking, gastrointestinal upset, pesticide exposure, and psychological distress. Vulnerable groups like children and pregnant women have higher risks. Heavy infestations or frequent exposures raise greater concerns due to a larger pathogenic load.

Stay calm, watch for persistent symptoms, and take preventive measures to minimize cockroach encounters when cooking and eating. Getting sick from an occasional cockroach ingestion remains rare, but take sensible precautions. Be extra vigilant if you live in an area with endemic cockroach infestations to limit contact and consumption of these dirty pests.
