Consider this, if a cockroach were to walk across your table at a restaurant, you would leave immediately. However, if a fly were to land on your plate, you would probably just wave it away and carry on eating. Yet, the fly carries as much disease potential as a cockroach. Should it not be met with the same distaste and controlled with as much vigilance?

Flying insects have been found to carry a wide range of dangerous microorganisms all over their bodies, in their saliva and excreta, including E.coli, Salmonella, Klebsiella, Campylobacter and many others. Even a tiny dose of any contamination reduces product quality, making it unsalable - it is here that 'a fly in the soup' is no joke.
