Over in Socialist England, they’ve figured out how to stop salmonella in eggs by vaccinating chickens, using what appears to be a free market solution:
There are no laws mandating vaccination in Britain. But it is required, along with other safety measures, if farmers want to place an industry-sponsored red lion stamp on their eggs, which shows they have met basic standards. The country’s major supermarkets buy only eggs with the lion seal, so vaccination is practiced by 90 percent of egg producers, according to Ms. Cryer.
Thomas Humphrey, a food safety professor at the University of Liverpool, said that producers in the United Kingdom turned to vaccination after other measures, similar to those now required by the F.D.A., failed to show significant results.
Meanwhile, 142,000 Americans got sick every year from eating eggs inflected with salmonella.
