Avian Botulism is a strain of botulism that affects wild and captive bird populations, most notably waterfowl. This is a paralytic disease brought on by the Botulinum neurotoxin (BoNt) of the bacterium Clostridium botulinum . [ 1 ]
Ducks appear to be affected most often. An enzootic form of duck botulism in the Western US and Canada is known as "western duck sickness". [96] Botulism also affects commercially raised poultry. In chickens, the mortality rate varies from a few birds to 40% of the flock. Botulism seems to be relatively uncommon in domestic mammals; however, in ...
The Loch Maree Hotel botulism poisoning of 1922 was the first recorded outbreak of botulism in the United Kingdom. Eight people died, with the resulting public inquiry linking all the deaths to the hotel's potted duck paste .
Most people who develop wound botulism inject drugs several times a day, so determining a timeline of when onset symptoms first occurred and when the toxin entered the body can be difficult. It is more common in people who inject black tar heroin. [71] Wound botulism signs and symptoms include: [70] [72] Difficulty swallowing or speaking
Zebra mussels are believed to be the source of deadly avian botulism poisoning that has killed tens of thousands of birds in the Great Lakes since the late 1990s. [66] They are edible, but since they are so efficient at filtering water, they tend to accumulate pollutants and toxins, so most experts recommend against consuming zebra mussels. [67]
When hunters use lead shot, waterfowl such as ducks and other species (swan especially) can ingest the spent pellets later and be poisoned; predators that eat these birds are also at risk. [3] Lead shot-related waterfowl poisonings were first documented in the US in the 1880s. [ 4 ]
BAT is the only FDA-approved product available for treating botulism in adults, and for botulism in infants caused by botulinum toxins other than types A and B. BAT has been used to treat a case of type F infant botulism and, on a case-by-case basis, may be used for future cases of non-type A and non-type B infant botulism.
The red-throated loon is susceptible to avian influenza [60] and Type E botulism, [61] and is regularly killed by the ingestion of neurotoxins produced by "red tide" algal blooms. [62] During a 2007 bloom , large numbers of the birds also died of hypothermia , after their plumages became matted by a protein byproduct of the algae , which ...
