Hazard Recognition. The CDC estimates that 5.6 million workers in the health care industry and related occupations are at risk of occupational exposure to bloodborne pathogens, including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and others.
The other dairy I visited is called Fair Oaks Farms. Owned by nine families, it is located near an interstate highway that bisects flat corn, alfalfa, and soybean fields in Indiana. Fair Oaks is one of the largest dairy farms in the United States. It houses 30,000 cows and produces enough milk to slake the thirst of the entire city of Chicago, which is located 75 miles to the north.
In 1970, there were 658,000 dairy farms in the U. S. By 2006, according to the United States Department of Agriculture, that number had fallen to 75,000, a drop of an astounding 88 percent. And the plunge continues. But in the same period, the number of mega-farms with more than 2,000 cows rose by 104 percent.
