Apanel of 10 researchers who specialize in different sciences says meat is probably not a significant cancer risk.
They say the International Agency for Cancer Research (IARC) and United Nations Global Harmonized System for Classification and Labeling (GHS) use outmoded hazard-based schemes to evaluate cancer risks to the public.
"This hazard-identification only process places chemicals with widely differing potencies and very different modes of action into the same category," Alan Boobis, professor in the Department of Medicine at Imperial College in London, said in a news release.
"The consequences are unnecessary health scares and unnecessary diversion of public funds."
The commentary recommends updating evaluation approaches by international governmental organizations to use internationally accepted methodologies that are already used by government regulatory bodies for cancer risk assessment.
“Among those approaches are those of the World Health Organization's International Program on Chemical Safety (IPCS),” the researchers say.
