Pizza and lasagna with a dash of pesticides doesn't sound so appetizing but a Japan plant is now at the center of a food poisoning controversy because of that.

The largest seafood company in Japan finds itself in hot water when around 350 people across the country got sick and suffered food poisoning after eating food contaminated with malathion. The company is a subsidiary of Maruha Nichiro Holdings, according to the NHK.

Doctors said the victims in Japan all displayed symptoms of food poisoning like diarrhea and vomiting.

The company, Maruha Nichiro, told local newspapers that it was flooded with 460,000 calls from angry consumers who actually ate the frozen food products while others complained about the bad odor.

NHK reported that the pesticide could have been mixed into the products in the company's plant in Gunma, Tokyo.

The company withdrew 6.4 million products suspected to be contaminated but the damage was already done.

A spokesman for the company, however, demurred from commenting on the possible consequence of the bad PR resulting from the incident.

"We have to specify the cause first," the spokesman said as reported by AFP.

The AFP  added that it wasn't the first incident of food poisoning in Japan, a country that is almost paranoid over the amount of contaminants that goes into its food. In August 2012, a cabbage contaminated with E-coli bacteria killed seven and downed dozen others.

In a report by the Associated Press, officials of the Mahura Nichiro have already apologized last week and encouraged the public to refrain from consuming the contaminated products. Police have been brought in to investigate if the contamination was deliberate.

The report said that traces of malathion found on the samples were 2.6 million times than the safe limit.

According to the U.S. Centers for Disease Control, malathion is used to kill pests in farms and gardens. It is also used to kill fleas on animals as well as people. Without regulation, however, the pesticide can cause death.
