In a popular Youtube video about an investigation into Monsanto's push for BGH/BST by Fox News reporters (and their subsequent dismissal), at around 1:50, it claims that
"...the longest test they did for human toxicity was 90 days on 30 rats."
Is there proof to support this claim? Or rather, is there documentation existing showing that more testing was done than this?
Note: There are other questions S.SE regarding the safety, etc. of BGH, but I'm specifically addressing the claim that the human trial was so paltry.
