The U.S. Centers for Disease Control and Prevention met with state health officials to recommend personal protective equipment (PPE) for livestock farm workers. Principal Deputy Director Nirav Shah says the risk to the U.S. public remains low, however, states should act to protect people with work exposures including people on dairy farms, poultry farms and in slaughterhouses.

The CDC also urges farmers, workers and emergency workers to wear appropriate PPE when in close physical contact with sick birds, livestock, feces, raw milk or contaminated surfaces. Workers are encouraged to wear fluid-resistant coveralls a respirator or N95 mask, gloves, boots and safety goggles.

Only two people have tested positive for the HPAI virus in the U.S. The CDC also reports there have been no changes detected in the genetic makeup of the virus that would increase the likelihood of human transmission.
