dairy products containing rBGH
Prohibited in: Canada, European Union, Japan, Australia, New Zealand
Reason: Increased risk of cancer
It is highly likely that dairy products in the United States contain chemicals that may be toxic to humans and should be avoided unless the label states that they are free of rBGH. American dairy producers have used the growth hormone rBGH to increase the amount of milk their cows produce. Many countries, including Canada, have banned the import and sale of products containing rBGH because the growth hormone poses an additional cancer risk.
