In a new study of raw pork chops and ground pork, Consumer Reports found 69 percent samples were contaminated with Yersinia enterocolitica, according to a report published by the group today. A lesser-known foodborne pathogen, Yersinia enterocolitica can cause fever, abdominal pain and diarrhea, lasting one to three weeks, according to the Centers for Disease Control and Prevention. There is approximately one confirmed infection per 100,000 people reported each year, but since these cases are severely under-reported, CDC estimates there are actually around 100,000 infections in the United States annually.
Consumer Reports tested 198 samples and found that while the vast majority were positive for Yersinia, only 3 to 7 percent were positive for more the more common foodborne pathogens Salmonella, Staphylococcus aureus or Listeria monocytogenes.
According to the report, several of the isolates found were resistant to one or more antibiotics: Six of the eight Salmonella samples, 13 of the 14 Staphylococcus samples and 121 of the 132 Yersinia samples. The study also found MRSA on one sample.
The group points to the widespread use of antibiotics in agriculture as a key contributor to the resistance problem. Read more
