Bird fluhas gain the cattle . Health and agriculture officials announce this week that cattle in two states have tested positive for a straining of extremely morbific avian influenza ( HPAI ) , probably take in from idle birds . Though the computer virus seems to have come down the Bos taurus , it is not think to pose a gamy jeopardy to humans at this clip .
The discovery pass during an probe into outbreak of a mysterious illness affect cattle in Texas , Kansas , and New Mexico , which involved the U.S. Department of Agriculture , the Food and Drug Administration , the Centers for Disease Control and Prevention , and local agencies . OfficialsreportedMonday that sample distribution of unpasteurised Milk River collected from dairy moo-cow on several farm in Kansas and Texas have test electropositive for bird flu , specifically a strain of Type A H5N1 grippe .
The outbreaks largely touch on older oxen , which have commonly experienced symptom such as decreased milk production and low-down appetite . The investigation also found idle razzing in the vicinity of these outbreak , indicating their potential part as the origin . But initial testing of the influenza strain find in these cattle has not found any major changes that would make them more able to spread or do disease in humans , and there are presently no concerns about the virus reaching the public through polluted Milk River , functionary said .

“ There is no terror to the public and there will be no supply shortages , ” said commissioner Sid Miller in astatementfrom the Texas Department of Agriculture . “ No contaminated milk is known to have inscribe the nutrient chain of mountains ; it has all been dump . In the rare outcome that some affected Milk River enters the food string , the pasteurisation procedure will kill the virus . ”
Bird influenza is view one of the most probable germ to become a pandemic threat . The more often than not high-pitched mutation pace of influenza and the novelty of a strain that successfully jump from other animals to man could potentially create a virus that not only spreads rapidly but is much deadlier than the typical seasonal grippe .
Strains of H5N1 bird flu have been circulating for at least 25 years , activate large and mortal outbreak among wild wench and sometimes domestic poultry populations . But in late years , we ’ve part to detect more cause of boo flu in mammalian , including minks , ocean lions , and dolphins . Just last week , Minnesota officialsreportedfinding H5N1 grippe among infant goats live on a farm where an outbreak had lately infected poultry , the first such incident discovered in U.S. livestock .
case of H5N1 and other highly pathogenic avian flu strains in humans haveremained rare(if lethal ) and unmanageable to impart between the great unwashed so far . But the more spillover between birds and mammals that occurs , the more likely that impression could change . Last class , the World Health Organizationwarnedthat while the risk of H5N1 spreading to people is low for now , “ we must cook for any modification in the status quo . ”
