Tomatoes are being yanked from menus and grocery stores shelves after a 16 state salmonella scare hit the media on Monday.

The Food and Drug Administration says they are still looking for the source of the bad tomatoes. A lot of people normally eat tomatoes too.

"Tomatoes are one of the top 20 produce items selected by consumers," says Donna Garren, vice president of the National Restaurant Association.

The unused fruit will have to be thrown away. Most sellers say they'll have to likely have to send the rotten tomatoes to land-fills.

Symptoms usually start anywhere from six to 72 hours after becoming infected with salmonella bacteria. According to About.com, they include:

Headache
Abdominal pain
Diarrhea
Nausea
Fever (almost always present)
Dehydration, especially in babies and older adults.

Salmonella is the result of eating food contaminated with the feces from an infected animal or person. Gross.
