What's a good hamburger without tomatoes?

But, are they safe or aren't they?

At first, the Centers for Disease Control had the produce pulled from store shelves and off menus.

But, as testing continued certain types of tomatoes passed safety tests and went back on the shelves.

However, Salmonella cases continued popping up and over the past week the CDC admitted there may be "something else" behind the outbreak.

"Everything we have done and all of our conversations with people who have gotten ill and people who haven't gotten ill, probably 80-percent have eaten tomatoes so that's where the focus has been," said Emily Palmer, of the Dept. of State Health Service.

The CDC hasn't said what else may be linked, but it's looking at other produce.

So far, the health department has approved grape, cherry and tomatoes on the vine as safe to eat.

All Kentucky grown tomatoes are also safe.

Health experts still suggest that you wash your veggies before you eat them.
