Denmark Swine Fever Tests Negative
Laboratory tests were negative on tissue samples from a pig suspected of having classical swine fever, or CSF, that had forced the temporary shutdown of the Danish Crown slaughterhouse in Blans, Denmark, from Wednesday.
"The final result of the laboratory tests associated with the CSF suspicion on 24 September 2003 in a pig herd near Kolding does not show any presence of CSF-virus," reported the Danish Veterinary and Food Administration on its Web site on Sunday.
"The Danish Veterinary Institute (DVI) has conducted serological tests on blood samples from the herd as well as virus cultivation from the suspect pig from the herd and all these tests have been negative for CSF."
The DVI also said it has conducted serological tests on blood samples as well as virus cultivation from the herd on the island of Langeland, which closed the Danish Crown hog slaughtering facility in Odense. The preliminary results of these tests are negative. The herd does not show any signs of disease. The final results will be available on Tuesday, the DVI said.
These suspicions of CSF are the fourth and fifth in Denmark in 2003. Four of have proven negative, DVI said.
