Poland yesterday banned Irish livestock and farm products from transiting the country following the Co Louth outbreak, veterinary officials said.
Similar bans have been introduced on livestock and farm products from Britain, France and the Netherlands.
Uruguay's government decided to ban imports of fruit and vegetables from neighbouring Argentina, as a preventive measure against foot-and-mouth disease, a spokesman for the Ministry of Agriculture, Livestock and Fisheries said.
The spokesman, Mr Hipolito Tapie, said the measure was aimed at stopping any indirect contamination from Argentine-grown produce.
Argentina last Tuesday officially acknowledged the existence of 25 confirmed locations in which there were unspecified numbers of foot-and-mouth cases, and another 28 locations as yet unconfirmed but under suspicion.
In Italy, veterinary officials confirmed a seventh case of BSE after analysing tissue samples from a dairy cow in the central Marche region.
Italy introduced mandatory tests at the start of this year. So far, 52,759 animals have been tested after being slaughtered, the health ministry said yesterday. The latest known carrier of the disease is a seven-year-old cow reared locally.
The farm concerned was placed under quarantine after an early test found the animal carried the pathogen that causes bovine spongiform encephalopathy (BSE), or mad cow disease.
More than 80 people, mostly in Britain, have died after contracting its human equivalent, variant Creutzfeldt-Jakob Disease (vCJD). There have been no reported cases of the human illness in Italy.
Meanwhile, in Tuscany, officials ordered an inquiry after documents were apparently forged to make 18 calves from the Venice region seem younger than they were so they could bypass the mandatory BSE testing programme.
Police said the animals were alleged to be between nine and 11 months old when they had developed horns and teeth that indicated they were more than two years old.
The animals were born near the central city of Perugia and raised in the Rovigo area, south of Venice.
They were slaughtered near Pisa under regulations applied to calves 30 months and older and tested for possible BSE infection.
