The other night my husband put some canned tomatoes in a dish that seemed hot even to him, so he added ketchup! Yes, ketchup. Don’t ask me why. He didn’t mention it and when I had a helping of the dish my mouth burned for two hours. It had chilis in it. I don’t eat hot, spicy food.

I like spices in spaghetti sauce and other dishes, but not the hot kind. I don’t eat red peppers (the hot kind) or any other peppers if they are the least bit hot. I don’t even eat the peppers on a salad from Olive Garden or on pizzas from Papa John’s. I won’t touch the food that comes into contact with them, but eat from the other side of the container.

Now comes news that salmonella has been found on a single jalepeno in Texas.

Government inspectors finally have a big clue in the nationwide salmonella outbreak: They found the same bacteria strain on a single Mexican-grown jalapeno pepper handled in Texas — and issued a stronger warning for consumers to avoid fresh jalapenos.

But Monday’s discovery, the equivalent of a fingerprint, doesn’t solve the mystery: Authorities still don’t know where the pepper became tainted — on the farm, or in the McAllen, Texas, plant, or at some stop in between, such as a packing house.

Nor are they saying the tainted pepper exonerates tomatoes sold earlier in the spring that consumers until last week had been told were the prime suspect.

Still, “this genetic match is a very important break in the case,” said Dr. David Acheson, the Food and Drug Administration’s food safety chief.

For now, the government is strengthening its earlier precaution against hot peppers to a full-blown warning that no one should eat fresh jalapenos — or products such as fresh salsa made from them — until it can better pinpoint where tainted ones may have sold.

Tomatoes currently on the market, in contrast, now are considered safe to eat.

The Texas plant, Agricola Zaragoza, has suspended sales of fresh jalapenos and recalled those shipped since June 30 — shipments it said were made to Georgia and Texas.

If you like jalepenos be sure to eat them from a jar and not fresh until the all-clear has been given.
