Many farms were already following most of the new guidelines on their own, according to Krista Eberle, director of food safety programs at United Egg Producers, an egg farmer cooperative that includes at least one of the farms implicated in the recall.
With the new rule, however, tougher controls will be required and overseen by the FDA.
Acheson says the extent to which this new rule is enforced will be a key factor in whether the new regulations actually reduce salmonella deaths by 50 victims per year, as the FDA says it should.
Enforcement of new policy has been a perennial problem in food regulation, he says, as the resources necessary to police inspections is often inadequate.
Without the spectre of looming government inspections, many farms may not have incentive to improve their standards, Acheson says, so without the power and ability to inspect and penalize, any new regulation would be worthless.
"Regulation is key, but without the capacity to implement it, it's just a paper tiger," he says.
