In most cases, food that has been found to have a fly on it does not need to be thrown away.
Although flies carry bacteria, viruses and parasites from waste to food, a single touch will not cause illness.
Flies that have remained on food or food preparation areas for some time are more of a concern, The University of Sydney reports.
Experts say the longer a fly is on food, the higher the chance that pathogens will multiply and grow on the food.
In this case, the health risks increase significantly.
Moreover, a large number of flies will prove to be an even more alarming problem, as there is a higher risk that they have come into contact with dead animals and waste.
Therefore, when preparing and storing food, it is important to ensure that it is not left in the open access of flies and other insects.
