HIGH levels of pesticides and other harmful products in the country's fresh produce is caused by illegal trade in pest control products, Agriculture Secretary Felix Koskei has said.
Koski said many business peolpe are dealing in pest control products that are not registered or verified by the regulatory agencies.
"If you look at it well,the businessmen are selling counterfeit products that has cost us a lot as a country,"he said.
Early this month, the European Union banned the exportation of fresh products from Kenya on accounts of high levels of maximum residuals limits.
Koskei warned those trading in illegal products that they will soon be "caught and stern action"taken against them.
"The government will not allow a few people to destroy the market for the entire country.We shall crackdown on you,"he said.
The CS also told the farmers to be careful when buying pesticides to ensure they buy certified products.
He however said the government has held talks with the EU to reconsider their decision of banning the country's horticultural products.
