(CNN) -- The Irish government ordered a recall Saturday of all pork products linked to pigs slaughtered in Ireland, after laboratory tests found the presence of dioxins in animal feed and pork fat samples.



Preliminary evidence gathered by Ireland's Food Safety Authority indicated that the contamination likely started in September, the government said in a statement.



The Food Safety Authority advised consumers not to consume Irish pork and bacon products for the time being.



The government is now trying to determine the scope of the contamination.



Dioxins are environmental contaminants, often present in industrial waste. Most dioxin exposure occurs through diet, with more than 95 percent coming from the consumption of animal fats, according to the U.S. Environmental Protection Agency. Dioxin levels in food are regulated.



Dr Tony Holohan, Ireland's Chief Medical Officer, said that the dioxin usually impacts the nervous system and liver in comments reported by the UK Press Association. Holohan added that the dioxin would only be perilous through prolonged exposure.



The agency reported that an animal feed ingredient supplied by one business to 40-plus farms is regarded as the likely cause of the dioxin by experts, and that tests revealed the dioxin polychlorinated biphenyls to be 80 to 200 times above the acceptable safety level.
