I’m going to blow it away, but it’s disgusting to eat it for nothing.
Is it okay to eat the food that flies landed on and left??
Theoretically, if the flies have been sitting on the food for a long time, it’s best to remove that part and eat it. Simply put, flies drool, vomit and defecate on food, which can transmit more than 100 different diseases.
In fact, a study conducted in 2017 found that flies usually have pathogens on their legs because they spend their time in garbage and animal droppings. Then, when it lands somewhere, it delivers pathogens to that surface.
Flies deposit vomit and feces on food surfaces.
Above all, the way the fly sits on the food and eats it is more terrifying than I thought. Flies do not have teeth to masticate, so they vomit their food. They spit out digestive enzymes to break down food and suck it up. At this time, enzyme compounds contained in the fly’s saliva and vomit dissolve the food and break it down enough for the fly to suck it up easily. If a fly sits on one piece of food for a long time, it means that it is constantly working on this eating task.
Moreover, when a fly eats, it simultaneously defecates and lays eggs on it. It transfers pathogens that have already been buried in other secretions to the surface of the food, and there it leaves vomit, which is broken down in the fly’s mouth, on the food, and the residue is again buried on its legs and moves again. In this pattern, the fly is a transfer of many germs.
The longer the flies stay on the food, the more likely they are to pass on harmful bacteria, viruses and parasites. In fact, because of this, flies are known to transmit infectious diseases such as cholera, dysentery, and typhoid fever. According to a study by Pennsylvania State University in the United States, at least 65 diseases can be transmitted by ‘houseflies’ alone.
If the fly really sat down and flew away within 1 or 2 seconds, you can just eat it, but if you feel uncomfortable, not eating it is also an option. In fact, we don’t know how many germs may have been transferred in a few seconds.
Food that flies land on, it’s not a health hazard
Although flies can carry everything from infectious diseases to germs and parasites, they pose no great threat to the average healthy person. In fact, the risk of getting sick from eating food on which flies land is relatively low.
Dr. Cameron Webb, an American food hygiene expert, explains that “it is highly unlikely that any germs transmitted by flies will make humans sick.” A single contact does not significantly affect a healthy person, and the human immune system is able to fight off these germs.
However, Webb explains, “the risk of fungal transmission by flies varies considerably depending on where you are in the world.” According to his research, flies living in urban areas are more harmful than flies living in rural areas. This is because populations tend to be limited in rural areas due to the presence of agricultural spraying fungicides and other chemicals. Flies are also more dangerous in developing countries. It is common in these areas to contract diseases such as cholera and typhus after consuming contaminated food.
Accordingly, Dr. Webb suggested, “If flies have landed on food in some countries or regions, it is better not to eat them even from a preventive point of view.”
