Hens might become the first live animals to require testing for salmonella, if new Food and Drug Administration (FDA) regulations are approved in the White House this month.

The proposals, which govern action to be taken if a flock of birds is found to be infected with salmonella, will make it necessary for farmers to disinfect hen houses, implement pest control measures and conduct annual testing for the bacteria.

They also include the implementation of "Biosecurity" measures such as restricting worker access and providing protective clothing.
The FDA has yet to conduct an investigation into the economic impact of such proposals. Officials are quoted in the San Francisco Chronicle telling farmers "the benefits far out way the costs" however.

It remains to be seen whether similar regulations will be drafted for cattle herds.
