Outbreaks linked to food, such as the current Salmonella outbreak involving peanut butter that has sickened more than 500 people in 43 states, account for only about 10 percent of intestinal infections, which are medically termed as enteric infections. The new study, in the February 15 issue of The Journal of Infectious Diseases, now available online, suggests that methods for controlling bacterial enteric outbreaks may not be completely relevant to controlling the other 90 percent or so that occur sporadically.The upshot? Don't eat recalled peanut-butter products. But don't fret, either. And, please, try not to swallow too much water when you go swimming.
...Analysis of the data suggested that non-food exposures pose risks of sporadic bacterial enteric infection that are comparable in magnitude to those of food exposures. In particular, one surprise was a strong association with swimming and other forms of recreational water exposure for all four types of infection.
