According to a Bloomberg News report from Japan, police in the Gunma prefecture are investigating an incident of pesticide contamination in frozen food products, which affected at least 890 people across the country.
The reports state that the pesticide malathion was found at levels 2.6 million times those permitted in food in samples of frozen croquettes manufactured by Maruha Nichiro Holdings Inc. at a plant in eastern Japan. People who consumed the contaminated product are reported to have noticed a strong odour and suffered from nausea and stomach pains.
Maruha Nichiro is recalling approximately 6.4 million bags of frozen foods after malathion was detected in products including croquettes, pizza and chicken nuggets. A spokesman for the company stated that they did not test for pesticides in their products, as there was no reason to believe that they would be present.
The police are now reported to be questioning 300 hundred employees at the Maruha Nichiro plant after local health officials found no evidence of contamination during food production at the facility.
