While some may argue that bird poop is natural, others may argue that bird poop is an excellent source of salmonella, campylobacter and others.

On September 4, 2007, Dennis Wasylyszyn, an employee of Aberdeen Farm Market in Coldstream, B.C., pled guilty in provincial court to one count of violating s.4(e) of the Food and Drugs Act by selling an article of food which was manufactured or prepared under unsanitary conditions. Mr. Wasylyszyn was fined $2000 for this violation.

The Canadian Food Inspection Agency explains that Mr. Wasylyszyn was preparing fresh, unpasteurized apple juice with a machine that was protected only by an open-raftered roof supported by four beams. The processing area was open to the air and there were indications birds were roosting in the rafters above the machine.

There was no evidence of illness related to consumption of the juice.
