A consignment of rice from Pakistan was found infested with one of the world's most destructive insect pests, Khapra beetle, by US customs officials at a port, officials said.
US Customs and Border Agriculture Specialists intercepted four Khapra beetle larva cast skins in the shipment of rice originating from Pakistan on September 8 at the Norfolk,Virginia port of entry.
The shipment was then sent back to Pakistan.
The skins were found inside a sea container shipment under a plastic liner between the rice and the container floor, the US Customs and Border Protection said in a statement.
Specimens were submitted to the US Department of Agriculture for testing and Norfolk Customs officials received confirmation that the specimens were Khapra beetles. This is the second Khapra beetle detection this year.
There were three Khapra beetle interceptions last year. It is considered to be one of the world's most destructive insect pests of grains, cereals and stored foods.
Insect pests, said to be less than one per cent of all species, are such insects that feed on, compete for food with, or transmit diseases to humans and livestock.
The Khapra beetle is labelled a 'dirty feeder' because it damages more grain than it consumes, and because it contaminates grain with body parts and hairs.
