Foam used in US avian flu outbreaks

The US government will use foam to kill commercial poultry instead of carbon dioxide in the event of an avian flu outbreak.

The US Agriculture Department announced on Monday (6 November) that it approved the use of water-based foam to suffocate floor reared commercial poultry to control avian flu in a flock.

Supporters of the foam method argued that it is safer as it reduces the number of poultry workers in contact with infected birds, but animal rights groups in America claimed that it is cruel as it suffocates the birds.
