According to yesterday’s Pittsburgh Post-Gazette, this decision comes after an investigation into last year’s outbreak at the Chi-Chi’s restaurant at Beaver Valley Mall – in Beaver County, not Allegheny. The outbreak was eventually linked to green onions from Mexico, not employee behavior.

Given that hepatitis A is a nationwide problem, considering that there were outbreaks in Georgia, Tennessee and in many western states, companies should be worried about their employees. But requiring mass vaccination in a county where there haven’t been outbreaks is overreacting – particularly when Chi-Chi’s has stopped using green onions altogether.

Hepatitis A can be contracted by eating contaminated food that has either been handled by someone with hepatitis A or someone whose hands have been contaminated with the virus, according to the Food and Drug Administration’s Web site.

People are now aware of the danger hepatitis A poses – and should continue to educate themselves of food’s potential dangers.

The fact is, eating anything comes with a certain amount of risk – there are high mercury levels in fish; botulism in canned goods; bovine spongiform encephalopathy in cows; Salmonella and E. coli in undercooked meat; and, released yesterday on Reuters, higher arsenic levels in chicken than expected. It’s a wonder people haven’t tried subsisting on Styrofoam and double-filtered water.

Keeping people informed is a better method than requiring a select group to get vaccines. That said, if companies are concerned about hepatitis A, then they should provide vaccines gratis, thus gaining safer employees and good press.

Hepatitis A is widespread in Mexico and is often carried into the United States by people going back and forth over the border, according to a Health Department spokesman quoted in the Post-Gazette.

In fact, some doctors consider it to be enough of a threat to call for vaccines in the New England Journal of Medicine. Their report recommends vaccines for high-risk groups, including people living in western states, drug users and people living in counties with a high incidence of hepatitis A – of which Allegheny County isn’t one. So kudos to the committee for picking the reasonable choice and not requiring unnecessary vaccinations.
