PHILADELPHIA (CBS) — The Centers for Disease Control and Prevention is warning people who might have consumed contaminated raw milk after a New Jersey woman became sick.

The CDC says those who drank raw milk from Udder Milk may have been infected with a rare germ called Brucella abortus RB51.

The CDC says the woman from New Jersey became ill after drinking the raw milk in late September.

The potentially serious germ could cause women to suffer miscarriage and other pregnancy complications.

“Because Udder Milk has not provided information about the farms that supply their milk, it has not been possible to trace the source of the woman’s infection. CDC scientists have been collaborating with state health officials on the investigation,” the CDC said.
