 Furthermore, while the relation between consumption of acrylamide and cancer in rats and mice has been shown, it is still not clear whether acrylamide consumption has an effect on the risk of developing cancer in humans, and existing epidemiological studies in humans are very limited and do not show any relation between acrylamide and cancer in humans.Food industry workers exposed to twice the average level of acrylamide do not exhibit higher cancer rates.Although acrylamide has known toxic effects on the nervous system and on fertility, a June 2002 report by the Food and Agriculture Organization of the United Nations and the World Health Organization attempting to establish basic toxicology (threshold limit value, no-observed-adverse-effect levels, tolerable daily intake, etc.)
