We strengthened epidemiological surveillance controls in response to the detection of cases of avian influenza in wild and backyard birds, with the objective of preventing its spread.
The agency said it is working in the four provinces with confirmed cases, as well as in "the province of Entre Rios, on the border with Uruguay (where cases have been reported), reinforcing controls and preventive measures."
The South American country declared a health emergency last week due to the presence of the virus. The disease had never before been detected in the country.
Senasa asked the productive sector to "reinforce management, hygiene and biosecurity measures in their poultry farms and to immediately notify any detection of nervous, digestive or respiratory clinical signs, decrease in egg production, water or feed consumption and high mortality in domestic or wild birds."
So far, outbreaks of avian influenza A(H5N1) have been detected in Canada, U.S., Chile, Colombia, Ecuador, Honduras, Mexico, Panama, Peru, Venezuela, Bolivia and Cuba.
