Cockroaches are one of those bugs that make us all shudder. Their nesting and feeding habits cause them to carry a number of disease-causing pathogens on their bodies, while also ingesting these microorganisms from the rotting materials they feed on. Cockroaches feed on anything food humans would consume, in addition to other things such as leather, cardboard, feces, and even fingernails and toenails of sleeping people.
For businesses that handle food, they are a sign of poor food handling and storage practices that are a breach of food safety standards and regulations and can result in the revocation of their license.
In Tupelo and the northern MS area, we have about five different roaches we deal with on a daily basis: the German cockroach (the most common and hardest to get rid of), American cockroach, brown-banded cockroach, smoky brown roach, and the wood roach.
Diseases spread by cockroaches
Cockroaches don’t transmit diseases to humans with bites like a mosquito, tick, or flea would. Instead, they transmit them indirectly. People can become ill by consuming foods that have been contaminated by cockroaches, or who handle food on surfaces that have been contaminated by cockroaches.
According to the World Health Organization (WHO): “Cockroaches are one of the most significant pests found in apartments, homes, food-handling establishments, hospitals, and healthcare facilities worldwide.”
Over 60 pathogenic bacteria, molds, fungi, viruses, and parasitic worms have been found in cockroaches, including:
• E. coli
• Staphylococcus faecalis
• Staphylococcus aureus
• Shigella dysenteriae
A study reported by the World Health Organization states that many of the collected Salmonella samples showed resistance to antibacterial drugs, making infection control even more difficult.
Asthma issues caused by cockroaches
The existence of cockroach allergies was first documented in 1943 when patients developed rashes where cockroaches had crawled on their skin. In some people, the proteins in cockroach feces and body parts not only produced an allergic reaction but triggered asthma. Tiny particles from cockroach body parts and dried feces can spread through the air, exposing residents in buildings and houses to the allergens.
According to the American College of Allergy, Asthma & Immunology, feces, saliva, and shed body parts from cockroaches can trigger asthma and various allergic responses. Studies worldwide have discovered high levels of exposure to cockroach allergens when testing people living in urban areas, indicating a high level of cockroach infestations in their homes.
This finding was reinforced when the US National Pest Management Association found that although approximately 63% of U.S. homes contained cockroach allergens, this level rose to 78% – 98% in urban homes. Other sobering statistics about cockroach exposure include:
• In the US, cockroach allergen exposure was found in 60-80% of inner-city children with asthma.
• In Poland, cockroach exposure was found in approximately 25% of children with asthma.
• In China, cockroach allergens were found in 11-98% of dust samples taken from nine cities.
• In Taiwan, cockroach exposure was found in 58% of all people with asthma.
How cockroaches can spread diseases
Cockroaches spread diseases in multiple ways:
2. vomit and saliva
3. Physical contact with food and surfaces
One way cockroaches transmit disease is by passing along harmful pathogens in their droppings (feces). After a cockroach eats something contaminated like raw chicken or animal feces, the microorganisms in whatever they ate get into their digestive system and either lay dormant or multiply. The pathogens will then be excreted in the cockroach feces and will contaminate any surfaces or food that the cockroach crawls on.
Cockroach vomit and saliva
Cockroach vomit and saliva can also spread microorganisms. Cockroaches frequently excrete saliva onto food before eating it and also periodically vomit partially digested food. Both of these actions can result in the spread of microorganisms when people eat contaminated food materials.
Cockroaches like to frequent unclean environments that provide shelter, food, and an environment to survive. These include garbage bins, sewers, drains, and cesspits – places in which there is a range of microorganisms such as viruses, bacteria, and fungi. These attach to cockroaches’ bodies as they move around the environment.
Cockroach legs, for example, have long spines with a very large surface area which can pick up microorganisms. Anything these spines touch or rub against when the cockroach moves around may then become contaminated.
How can you catch a disease from a cockroach?
There are a variety of different ways that cockroach infestation can result in disease transmission to humans. The majority of cockroach diseases are caught either by eating contaminated food or coming into direct contact with things that a cockroach has contaminated.
Eating and drinking contaminated food
The most common method of disease transmission is through eating or drinking anything a cockroach has contaminated. This can happen directly when consuming drinks or food contaminated by cockroaches, or indirectly by drinking or eating something that has been in contact with contaminated cutlery, cooking utensils, crockery, or contaminated surfaces.
Inhaling contaminated air
If the dust in the air supply is contaminated with particles of cockroach feces, vomit, dried saliva, or shed skin, it can trigger an asthma attack in people suffering from asthma after they inhale the contaminated air.
Touching contaminated items
Touching items contaminated by cockroaches is another way transmission can occur. When someone touches a contaminated item, then touches their eyes, mouth, nose, or an open wound, they allow the microorganisms from the contaminated object/surface to enter the body and cause infection.
How to prevent the spread of disease by cockroaches
The best way to prevent cockroaches in your home or business (and the resulting spread of disease pathogens) is to maintain good food hygiene. The removal of any food sources (even tiny spills and food particles) reduces the possibility of cockroaches being attracted to and entering your property.
Good food hygiene includes:
• Overall elimination of cockroach food sources
• Consistent, thorough cleaning of areas where food is prepared, stored, eaten, and cooked
• Sealing gaps and cracks that cockroaches can enter through
• Wash hands frequently to prevent pathogen transmission from contaminated objects and surfaces
