People who consumed raw milk or raw milk products from one Texas dairy should contact their healthcare provider immediately, warn health investigators from the Centers for Disease Control and Prevention (CDC) and the Texas Department of State Health Services (DSHS). Raw milk from the K-Bar Dairy in Paradise, Texas (outside Dallas/Fort Worth area), tested positive for a rare but potentially serious bacteria known as Brucella RB51.
CDC advises that people who consumed milk or milk products from the K-Bar Dairy between June 1 and Aug. 7, 2017, should get antibiotic treatment to avoid lifelong, chronic infections. Initially, people with brucellosis experience fever, sweats, aches and fatigue. If not treated, Brucella RB51 infection can result in long-term symptoms like arthritis; swelling of the heart, liver or spleen; and, in rare cases, neurologic issues like meningitis. RB51 can cause severe illness in people with weakened immune systems and miscarriages in pregnant women.
“It’s very important for people who drank this raw milk to seek treatment to prevent infection with Brucella RB51,” said William Bower, M.D., team lead for the CDC group that investigates brucellosis. “Even if people don’t have any symptoms now, they can develop a chronic infection that can impact their health for years to come.”
One illness in a Texas woman has been linked to the dairy. Purchase records and illness reports indicate additional people in Texas and some as far away as California and North Dakota may need antibiotics to prevent or treat infection.
CDC and Texas health officials have been trying to reach people in more than 800 households known to have purchased K-Bar raw milk. Texas is following up with 170; CDC tried to contact the remaining 672 households but many did not provide contact information. Of the 485 households with contact information, CDC successfully reached 236 households. Among the 236 households, 83 percent of people were exposed to RB51 by drinking the milk. Nearly a third of those who reported being exposed to the raw milk said they had an illness in the past couple months. Additional testing is necessary to determine if the illnesses are due to Brucella RB51.
Due to incomplete contact information, CDC staff have been unable to reach about 200 households who bought K-Bar milk. People who sampled the milk at the dairy or got the milk from friends or family also may not be aware of their risk.
So far, CDC and Texas health officials have received reports about people who drank K-Bar milk or have symptoms similar to brucellosis caused by RB51 in Alabama, Arkansas, California, Ohio, North Dakota, Tennessee and Texas.
CDC recommends that anyone who drank raw milk or consumed milk products from K-Bar dairy between June 1 and Aug. 7, 2017, see their doctor for antibiotics to prevent infection. Because Brucella can cause complications during pregnancy, including miscarriage, it is especially important for pregnant women who may have been exposed to seek medical care. RB51 is resistant to some antibiotics that would normally be used to prevent or treat brucellosis, so people who drank the milk should tell their doctor that they may have been exposed to RB51.
People exposed to the milk should also check themselves for fever for four weeks after they last drank the milk and watch for other brucellosis symptoms for six months. These symptoms include but are not limited to: muscle pain, lasting fatigue, arthritis, depression, and swelling of the testicles.
