Science Shows Just How Unsanitary Double Dipping Is

That first bite was good, but should you double dip for the next? Scientists now say it's more than just bad manners.
Researchers from Clemson University found that second, contaminated dip leads to hundreds of times more bacteria staying in the bowl than on the first dip in chocolate and cheese sauces.
But if there's one sauce you should definitely keep to a one-and-done rule, make it salsa.
