Samuel S. Epstein, MD, Chairman of the Cancer Prevention Coalition, wrote in a Mar. 20, 1994 article "A Needless New Risk of Breast Cancer," published in the Los Angeles Times:

“The FDA [United States Department of Agriculture] – approved label insert for Posilac [Monsanto brand Artificial Bovine Growth Hormone], a pamphlet that only dairy farmers see, admits that its ‘use is associated with increased frequency of use of medication in cows for mastitis and other health problems.’ Monsanto’s own data further show up to an 80% incidence of mastitis, an udder infection, in hormone-treated cattle and resulting contamination of milk with statistically significant levels of pus.”
