Fly may look like a minor nuisance, but it plays an important role in transmitting disease.
A recent study has concluded that flies are responsible for infecting spinach leaves with E.coli bacteria. The pathogenic bacteria survives on the flies for 13 days once it is picked up via contaminated cattle manure.
IN 2010, researchers from University of Florida collected number of house flies hovering close to binds outside several restaurants. They discovered 11 different pathogens on the flies – all of which leads to illness among humans, ranging from respiratory infections to food poisoning.
The researchers also figured that while 200 types of bacteria have already been documented, the number was sure to rise – and they can carry up to twice as many pathogens as cockroaches!
Flies are always in search of decaying food and waste, mostly because it becomes simpler for them to liquefy their food before ingesting it. Adding to the gross factor, they spread bacteria in really unappetizing ways, including regurgitating and secreting saliva as they liquefy their food, and defecating on food and surfaces which comes in close contact with humans.
While most people’s immune system shield them from germs carried by flies, some are more vulnerable to fly-related health risks – this includes infants, the elderly, people with compromise immune systems due to illness or chemotherapy.
Thus, it is highly important for you to think of flies as an imminent threat and it is necessary to take required steps to ensure that they don’t affect the health of your loved ones.
