BUENOS AIRES (Reuters) -Argentina's state sanitation agency Senasa on Friday ordered a suspension of imports of products and byproducts of avian origin from Brazil, the world's largest chicken exporter that hours earlier confirmed its first outbreak of bird flu on a commercial poultry farm.

"After the confirmation from Brazilian authorities, Senasa requested the productive sector strengthen biosecurity measures in its establishments," the agency said in a statement, adding the measures would be in place until Brazil is certified as free of the bird flu.
