Senior officials said on Tuesday a bird flu that devastated US poultry flocks this year is likely to get under control within few months.

Officials could say this after seeing result of the measures that were adopted by the United States to contain the virus. Summer weather has also played a vital role in weakening of the virus.

Head of the Paris-based World Organization for Animal Health said there is a high risk that bird flu strains might spread within the American continent, mainly Mexico. The organization seeing this has even asked farmers and authorities to boost biosecurity measures.

The US Department of Agriculture said in a daily notice that no new cases of the disease were confirmed on Tuesday. Iowa, the nation's top egg-producing state, and the top turkey producer Minnesota, found eight new poultry flocks that are thought to be infected.

The US poultry industry is battling with its biggest recorded outbreak of bird flu, which has led to the death or culling of more than 40 million birds. The flu infected commercial farms and backyard flocks in 16 US states and in Canada.

The disease also caused several physical symptoms and drop in egg production. It has led to sharp rise in egg prices, forcing food producers to look for alternatives.

OIE Director General Bernard Vallat said Reuters in an interview, "I think it cannot worsen in the United States. Given the scale of the damage and the pressure on farmers I believe they will quickly protect themselves more efficiently. There are huge economic stakes here".

He hopes that the epidemic would be under control by September.

The US chief veterinary officer John Clifford seeing the recent decline in number of cases and being more optimistic about the situation said the epidemic might come to an end in July.
