Flies are fascinating - Angela Cliff, KE Manager

undefinedFlies are fascinating!  Shropshire Pig Club had an evening learning about fly control with David Reece from Oakwood Farm Services and Farm Train. 

There are more than 100 diseases that can be transmitted by flies and up to 60 of these are zoonotic, ie can be transferred to humans. This is through either the nasty nippers or regurgitators sicking up their last meal. You don’t want to think about what that might have been!

The group heard about control methods for both straw and slurry-based systems, but the message was, get them while they are young as larvae. He also advised doing regular fly counts just in case there are any complaints against you and the local environmental health officer comes a-calling. 

Two further evenings on this topic will be held on 6 and 7 April at the Fens Pig Club and Midlands Pig Club, respectively. More information on the AHDB Pork website.

You mention that there are more than 100 diseases that can be transmitted by flies and up to 60 of these are zoonotic, ie can be transferred to humans. Please can you mention which of these can be transmitted to humans please. Thank you.

While we don't have a specific list of diseases, there are a couple of points about pathogen transfer from flies. There are basically two main routes: what is what is regurgitated up onto the surface from the fly's gut when it's feeding and what is on their feet when they land on your food. There's a paragraph here from draft Environment Agency guidance (March 2013): Adult flies are often active on putrescent and microbially contaminated substrates. As a result, their external surfaces and gut will become contaminated with a broad range of pathogens. If these contaminated flies subsequently come into contact with people, livestock or foodstuffs, there is the potential for disease transmission. In the tropics a major source of infections in humans can be traced back to houseflies. Although fly numbers and the opportunities for contamination in the UK are typically much less, a small risk still remains.
