Ordinarily, according to this story, the relationship between houseflies and
poultry farms needs no introduction. The common housefly otherwise known as
Musca domestica feeds and breeds on all kinds of organic matters that include
food and animal feed, garbage, faeces, sewage and animal carcasses.
In an average farm, houseflies constantly shuttle between dirty areas with
pathogens and clean areas such as feed storage and animal housing.
But this is where the problem lies. Due to this nature of movement, houseflies
have over the years been implicated in the transmission of over 30 different
types of diseases caused by bacteria, protozoan and viral parasites.
And the dreaded Avian Influenza is not an exception. A recent research at the
North Carolina State University, United States of America has revealed that the
common houseflies can indeed transmit the AI virus within a farm.
In arriving at this conclusion, the researchers said they got the first hint
that houseflies could act as a carrier of the highly pathogenic H5NI strain of
avian influenza, when "more than one-third of the adult Musca domestica sampled
contained AI virus particles."
The researchers were also cited as saying that houseflies could also transmit
the Newcastle Disease whose virus has since been known as a dedicated disease of
the poultry.
To buttress their point, they noted that houseflies were well established
vectors of food poisoning bacteria like Salmonella.
Nigerian veterinary doctor and Deputy Chairman, Poultry Association of Lagos
State, Dr. Babatunde Bello was cited as saying "Houseflies can contaminate
foods, hands and farm implements and can create a lot more problems in the farms
if not properly handled."
