“I was speaking out, but it was my duty to speak out.”
– Dr Shiv Chopra, September 2017
Dr. Shiv Chopra was a veterinary scientist with a Ph.D. in microbiology. He was a senior scientist at Health Canada (Canada’s food safety regulator) where he worked from 1969 until 2004. Dr. Chopra was one of three Health Canada veterinary scientists who spoke out in the 1990s about pressure to approve animal drugs despite their concerns about animal health and food safety. They questioned carbadox, a drug used in pigs, and Baytril, which was used to promote growth in cows and chickens. Most prominent were their concerns over Monsanto’s genetically engineered veterinary drug Bovine Growth Hormone (BGH). Their public criticisms of BGH were met with gag orders from their employers at Health Canada but finally led to Senate hearings and a 1999 decision not to approve the drug.
