One hundred forty eight people across four states were sickened in January 2012 with camphylobacter bacteria that was traced back to raw, or unpasteurized milk sold by a Pennsylvania dairy farm. As MSNBC.com reports, the milk outbreak affected people from ages 2 to 74, and is particularly alarming because the dairy had all its proper permits, and had passed all inspections required for selling unpasteurized milk:
The [CDC] report, which details what happened during the outbreak, said the dairy that sold the milk had a permit for selling unpasteurized milk, and had passed all inspections. The farm was among the largest sellers of unpasteurized milk in the state.
The dairy also tested its own milk for E. coli bacteria more often than was required. The vast majority of the sick people drank the milk before its “best by” date.
The only deficiencies that investigators found were that a mechanical milk bottle capper was broken, so employees had capped the bottles by hand, and that the water used to clean equipment was cooler than recommended (110 to 120 degrees Fahrenheit, instead of 160 to 170 degrees F).
But these issues were “minimal,” and this campylobacter outbreak demonstrates “the ongoing hazards of unpasteurized dairy products,” according to the report authors from the Centers for Disease Control and Prevention and state health departments. The findings were detailed online April 26 in the journal Clinical Infectious Diseases.
“Raw milk is riskier than most foods,” said Douglas Powell, a professor of food safety at Kansas State University. While certainly a larger number of people get sick yearly from eating tainted tomatoes or lettuce, there are many more consumers of those foods than consumers of raw milk, he said.
Bacteria commonly found in the digestive tracts of farm animals, including campylobacter and E. coli O157, can easily find their way into milk as it is pumped and bottled on a farm, Powell said.
“Fecal matter just ends up in the milk — it’s not like you can see it,” he said. “No inspectors can see it — this isn’t CSI, where the bacteria just magically line up.”
Nearly a third of those sickened in the outbreak were children, the report said. Children, along with pregnant women and people with compromised immune systems, are at high risk of complications from campylobacter infections.
Powell said he advises that raw milk not be given to children. “As adults, you’re free to choose,” he said. “But don’t give it to your kids.”
