Tuberculosis Passed From Zoo Elephants to People: CDC
People can get tuberculosis from infected captive elephants when they have long-term, close contact with the animals, a new study suggests.
In early 2013, an Asian bull elephant at a zoo in Multnomah County, Ore., tested positive for active tuberculosis, and the disease was later found in two other bull elephants.
Officials also tested 96 people who had contact with the three elephants and found that seven of those who had extensive contact with the animals had latent tuberculosis, which means they had no symptoms and were not infectious.
The three elephants were isolated and treated to prevent them from infecting other animals and people, and the seven affected people were offered treatment.
The findings show that captive elephants are a potential source of tuberculosis infection in people who have long-term, close contact with infected animals. Improved understanding of how the disease is transmitted between elephants and humans is needed in order to determine ways to reduce the risk of infection, the researchers said.
The study appears in the Jan. 7 issue of Morbidity and Mortality Weekly Report, published by the U.S. Centers for Disease Control and Prevention.
90,000 Pounds of Beef Patties Recalled
Nearly 90,000 pounds of beef patties are being recalled by a Minnesota company due to possible contamination with wood materials.
The recall by the Huisken Meat Co. is for 2-pound boxes of Sam's Choice Black Angus Beef Patties with 19 Percent Vidalia Onion. The patties were produced between Nov. 19, 2015, and Dec. 9, 2015, the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) said.
The products were shipped to stores nationwide.
There are no confirmed reports of injury or illness, according to FSIS.
Consumers who bought the recalled patties should throw them away or return them to the place of purchase. For more information, consumers can call the company at 618-857-4011.
