Only one mutation
A study from December published in the journal Science showed, that a strain of virus found in milk cows in the US may need only one mutation, to be distributed to people – noted the American Veterinary Medical Association (AVMA – American Veterinary Association ) in a report.
The longer this virus circulates uncontrolled, the more likely that there will be mutations necessary to cause a pandemic. We must act urgently, to prevent such a scenario
– said dr Les Sims, in a statement released by the organization, quoted by Independent.
Flu birds have also been detected in pigs, birds and cats from the west coast of the States United States, who drink raw milk and eat fed from farms for animals.

The Department of Agriculture is testing vaccines for poultry and cattle milk. Vaccination may however hinder differentiation of vaccinated animals from those naturally infected. Despite this Sims claims that the virus “fundamentally changed the way we must think about the management of the flu birds.”
We must act now, to protect the health of animals, protect our food systems and prevent a potential pandemic
