Brazil - Four new outbreaks of CSF

16-Jun-2009
The OIE has reported 3 new outbreaks of classical swine fever in Rio Grande Do Norte and 1 in Amapá. The three new outbreaks in Rio Grande Do Norte were detected by the surveillance programme and have an epidemiological link with the "Jucurutu 1" outbreak, where animals from the farm considered to be the index farm were introduced. All farms are for self-consumption or local trade. The State of Rio Grande do Norte is located outside the area declared at a national level as free of classical swine fever. The Animal Health Department has approved the vaccination of all pigs of the State of Rio Grande do Norte. Vaccination remains prohibited in the rest of the country. In Amapaá, the affected farm, of a traditional type, is for self-consumption. The State of Amapá is located outside the area declared at a national level as free of classical swine fever. Surveillance and epidemiological investigation are continuing.

USA - California bill on antibiotic use in livestock defeated

10-Jun-2009
A bill that would have affected the use of antibiotics in livestock has been defeated by the California Senate by a vote of 20-15. The bill would have required all school districts in California to make every effort to purchase poultry and meat products that had not been treated with non-theraputic anitibiotics. The original bill was even tougher. It would have prohibited schools from serving poultry or meat products from animals that had been treated with antibiotics at any time during the life of the animal.

USA - Recent results from studies with H1N1 influenza A virus

02-Jun-2009
Limited cross-reactivity of serum samples from pigs infected U.S swine influenza viruses or vaccinated with commercial vaccines was demonstrated against the new S/O H1N1 influenza virus (A/CA/04/2009) as measured by the standard HI test. The results of this experiment suggest that pre-existing immunity induced by swine influenza viruses circulating in the U.S may not protect pigs against the new S/O H1N1 influenza virus presently circulating in people. Importantly, vaccines currently used to protect pigs in U.S swine operations against swine influenza virus may not be effective against the new S/O H1N1 influenza virus.

North American H1N1 influenza update

The usual pig viruses are H1N1, H3N2 and H1N2. The original H1N1 pig viruses have been largely replaced by poultry viruses in pigs. The H3N2 viruses were from humans originally. The H1N2 viruses are re-assortants from human viruses (H and N genes) and poultry viruses.

Taiwan - Foot and mouth disease: Sub-clinical infection

26-May-2009
In order to ensure the eradication of FMD virus, Chinese Taipei uses non-vaccinated pigs as sentinel animals on every farm. During the routine active surveillance in the livestock market, a pig was found NSP antibody positive. The prefecture animal disease control competent authority traced back to the original farm. The result of clinical investigation showed that all pigs on farm were healthy. Samples for serological tests and virus isolation were collected and sent to the National Laboratory. The laboratory confirmed positive results for NSP and negative for virus isolation. A total of 57 farms within 3-km-radius of the index farm have been under vigilant monitoring and no clinical or serological evidence of infection has been found.
