Brucella in Raw Milk Prompts Health Warning in Texas

JAMA. 2017;318(16):1533. doi:10.1001/jama.2017.15338

Officials from the CDC and the Texas Department of State Health Services warned last month that anyone who had recently consumed raw milk from a certain Texas dairy should receive postexposure prophylaxis to protect against a rare but potentially serious bacterial infection.

Raw milk from the K-Bar Dairy in Paradise, Texas, tested positive for Brucella abortus strain RB51, which is used in vaccinating young female cattle against more serious Brucella strains. In rare cases, vaccinated cows can shed RB51 in their milk. The warning from CDC and Texas health officials pertains to K-Bar raw milk consumed between June 1 and August 7.
