A study released this week said campylobacter cases grew by 14 percent over the last five years.
The Centers for Disease Control and Prevention report was based on foodborne infections in only 10 states — about 15 percent of the American population. But it is seen as a good indicator of food poisoning trends.
Overall, food poisonings held fairly steady in recent years. There were no significant jumps in cases from most other food bugs, including salmonella and E. coli. But campylobacter rose, and last year accounted for more than a third of food poisoning illnesses in those states and about a 10th of the deaths.
