... Regulation does.
Once again, the repugican myth of self-regulation is a key part of the problem. Whether it's food safety, insurance, banking, you name it, the fantasy world that has been a key component of repugican policy since the Reagan years has repeatedly been proven to be a joke. Unfortunately consumers keep having to pay the price for bad policy. In theory the Democrats could and should start running harder against self-regulation but their cooperation over the years was critical for any of this legislation to succeed.
Faced with a crisis more than a decade ago in which thousands of people were sickened from salmonella in infected eggs, farmers in Britain began vaccinating their hens against the bacteria. That simple but decisive step virtually wiped out the health threat.
But when American regulators created new egg safety rules that went into effect last month, they declared that there was not enough evidence to conclude that vaccinating hens against salmonella would prevent people from getting sick. The Food and Drug Administration decided not to mandate vaccination of hens — a precaution that would cost less than a penny per a dozen eggs.
