Jonathan D. Rockoff of The Baltimore Sun reports today that,
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. …
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. …
One health official involved in the investigation said "loose ends" are keeping tomatoes under suspicion, but the official said they could be accounted for easily. The official said evidence is "piling up" that indicates that jalapenos are to blame.
"There’s certainly no shred of doubt in my mind," the official said.
Another health official was more cautious, saying that the evidence is pointing to peppers but that there is not yet enough information to rule out tomatoes.
