Avian Influenza found in New Jersey market

USA, New Jersey 12 February, 2004 A strain of avian influenza has been found at four live chicken markets in northern New Jersey, just days after outbreaks at two farms in Delaware led to the destruction of thousands of birds.
Officials said the strain found in New Jersey is the same one found at two farms in Delaware since last week.
This Avian Influenza strain H7N2, has been found among birds in northeastern U.S. markets since 1994. It was also recorded in poultry in Pennsylvania during 1997, 1998; in Virginia an North Carolina in 2002 and in broilers in Pennsylvania in November 2001- January 2002.
A survey by USDA-APHIS-VS in the fall and winter of 2001 found 56.9% of 111 live-bird markets in metropolitan New York and New Jersey contaminated with the H7N2 virus. This virus was genetically similar to the avian influenza virus isolated in the Pennsylvania 2001 – 2002 outbreak. The live bird markets have been and will likely continue to be a source of avian influeza viruses for commercial poultry.
