Agriculture officials say they have identified a shipment of corn from Nicaragua as being contaminated with aflatoxin. The Servicio Fitosanitario del Estado confirmed the contamination based on results from the Laboratorio del Centro de Investigación en Granos y Semillas at the Universidad de Costa Rica.
The shipment is 21,818 kilos in three containers. The loads were checked at the Peñas Blancas border crossing, officials said. They were not permitted to enter the country, officials said.
Aricultural officials said that the contamination amounted to from 62 to 91 parts per million when the permitted level is 20 parts per million. Aflatoxins are produced by a small fungus and they can be toxic and even cause cancer, said agricultural officials.
