Yes. Feeding old and moldy bread is harmful. Feeding any kind of processed human food is harmful.
Wildlife should not be fed when ample food is already available in nature.
1.) Feeding ducks attracts rats, pests and predators that kill ducks and endanger humans.
2.) Rotting food pollutes the water and breeds deadly diseases and parasites…
• A single outbreak of Duck Virus Enteritis (caused by artificial feeding)
kills all of the ducks.
• Uneaten food quickly forms a deadly mold called Aspergillus;
fatal to ducks without early diagnosis and expensive treatment.
• Avian Botulism (caused by artificial feeding)
kills entire waterfowl populations and hospitalizes people.
• Artificially fed ducks emit a parasite causing a condition
in humans called Swimmer’s Itch.
3.) Ducks defacate at the site of scattered food or bread, bacteria in feces creates much higher risks for illness or disease.
4.) Most waterfowl die-offs in the past 10 years have been attributed to artificial feeding.
5.) Food waste bobbing on the water’s edge is ugly.
6.) Ducks that are overfed create dangerous amounts of waste that harms fish and other animals living in ponds.
7.) Some foods like corn may be OK as a snack for ducks, but fish can’t digest it and die. Seeds cause severe cramping pain in ducks.
