I saw on Fox News this morning that cetain types of tomatoes, from certain areas were possibly contaminated with salmonella. The FDA is recommending that restaurants not serve red plum, red roma, & round red tomatoes unless they come from certain states that have not had a problem. This is the address to check it out

It also cautions about salsa's etc. that are made with fresh tomatoes. It seems that you can't just wash the salmonella off, it is actually in some of the tomatoes. At the Farmhouse, we have thrown away the tomatoes we had and will not have any until we can find some that are approved as safe.
