WASHINGTON — WASHINGTON - Investigators are seeing more signs that the salmonella outbreak blamed on tomatoes might have been caused by tainted jalapeno peppers and have begun collecting samples from restaurants and from the homes of those who have been sickened, according to health officials involved in the probe.
New interviews with those who became infected found that many had eaten jalapeno peppers, often in salsa served with Mexican food, according to two state health officials. So far, none of the jalapenos taken from restaurants and from the homes of those who became ill have tested positive for Salmonella saintpaul.
Echoing federal officials, who said this week that tomatoes remain the prime suspect, the health officials said that tomatoes cannot be ruled out as the cause of the outbreak. Investigators have been collecting samples of another possible suspect, cilantro, though the herb is less likely to be the source, said the officials, who spoke on condition of anonymity because the investigation is continuing.
The outbreak, which began 12 weeks ago, is believed to be the largest of its kind, and new cases continue to emerge. It has sickened more than 920 people across the country, up from 756 one week ago, and sent more than 110 to the hospital. In Maryland, 29 people have been confirmed to have the illness, which can cause nausea, vomiting and diarrhea, and, in severe cases, death.
In late May, investigators began focusing on tomatoes as the probable source of the outbreak. But they expanded their investigation last week, asking 100 labs around the country to help, because the number of new infections kept growing despite the short shelf life of tomatoes and warnings to avoid certain varieties.
Delays in pinpointing the cause of the outbreak have frustrated consumers, angered the produce industry and prompted members of Congress to call for food safety reforms.
"How sad is that? We can't even really figure out what it is," said Rep. Diana DeGette, a Colorado Democrat who has proposed food tracking and mandatory recall measures. "We've had the same problem with other products in past years, which shows us the food safety system in this country is outdated and underfunded."
Chile peppers are largely grown in Mexico, Central America and warm weather U.S. states such as Florida. Food-safety specialists said jalapenos are not a common cause of bacterial outbreaks and counseled caution about rushing to judgment that the peppers are responsible for this one.
