Bird flu, uncooked milk may be contaminated with the virus: here’s a new examine.  Scientist: “Don’t drink it”

Raw milk generally is a vector for the H5N1 virus, accountable for chicken flu. A examine carried out by Yoshihiro Kawaoka, a virologist on the University of Wisconsin, confirmed that mice fed contaminated uncooked milk grew to become sick extra rapidly. Traces of this virus have been discovered in lots of animal organs. The outcomes of the examine, printed within the New England Journal of Medicine, will not be totally shocking: not less than half a dozen cats died after consuming uncooked milk containing this virus. But new information affirm that uncooked milk stuffed with micro organism will not be secure for different mammals, together with people. “Don’t drink uncooked milk: that is the message”, emphasised Kawaoka. Most business milk within the United States is pasteurized. The Food and Drug Administration has discovered traces of the virus in 20% of dairy merchandise taken from grocery store cabinets. American company officers discovered no indicators of the contagious virus and stated pasteurized milk is secure to devour. However, the findings of this new examine have world implications. “If the epidemic continues to unfold amongst cattle, there shall be different areas the place animal grazing is not doable – warns Nahid Bhadelia, director of the Center for Emerging Infectious Diseases at Boston University, within the New York Times – and there are numerous rural communities that drink milk.”

Researchers analyzed the virus remoted from milk samples from a herd contaminated with the H5N1 virus in New Mexico. However, the researchers discovered that ranges of the virus step by step decreased in a pattern of milk saved at 4 levels Celsius, suggesting that H5N1 in refrigerated uncooked milk can stay contagious for as much as a number of weeks. Influenza viruses thrive in fridge temperatures, and milk proteins additionally assist to strengthen them. If individuals who drink uncooked milk imagine that refrigeration kills micro organism, a brand new examine clearly reveals that this isn’t the case. Mice fed contaminated milk rapidly grew to become ailing, exhibiting indicators of fur and lethargy. On the fourth day, the mice had been killed, and the researchers discovered excessive ranges of the virus within the respiratory system and restricted ranges in a number of different organs. Like the contaminated cows, the researchers additionally discovered the virus of their mouse mammary glands – an sudden discovery. “These rats do not suckle; nevertheless, the virus may be discovered within the mammary glands,” highlighted Kawaoka. “It’s very fascinating,” he provides. It is just not clear whether or not the presence of virus within the mammary glands is attribute of this explicit virus or of chicken flu viruses usually. Mice are sometimes present in livestock farms and thus symbolize one other potential host for the virus. Cats and birds that eat contaminated rodents, for instance, could change into ailing. Cats that died after ingesting contaminated milk confirmed important neurological signs, together with extreme physique actions, blindness, a bent to stroll in circles and a weak eyelid response. According to the researchers, if the mice had been allowed to stay longer, they could have comparable signs.

Importance of pasteurization

Pasteurization kills micro organism by heating milk to excessive temperatures. In the brand new examine, when the researchers heated the milk at temperatures and instances usually used for pasteurization, the micro organism was both invisible or drastically diminished, however not utterly inactivated. The researchers famous that laboratory situations had been completely different from these utilized in business processing. So the findings don’t imply that milk on grocery store cabinets accommodates lively micro organism. But the invention that uncooked milk accommodates a lot of micro organism is “sturdy”. Raw milk has change into widespread lately, promoted by wellness gurus and influencers. Some say it tastes higher and is extra nutritious than pasteurized milk. Some say it boosts the immune system. In distinction, pasteurization preserves calcium, the principle nutrient in milk, and provides vitamin D to help absorption. According to the Centers for Disease Control and Prevention, consuming uncooked milk can result in critical problems and even dying from quite a lot of micro organism, particularly in individuals with compromised immune programs.
