I'm not surprised Granny23
To be on the safe side, I've just washed mine thoroughly in very hot soapy water - the slots go all the way through so I rinsed in scalding hot water. I've also washed the already clean knives and that thing that sets your teeth on edge (sharpener)
Then I read the 'correct way' to do it:

First, remove the knives and turn the knife block upside down to shake out crumbs that may have collected inside. It may help to tap the underside with a small hammer to loosen debris.
Crumbs? How would crumbs get in there if the knives are clean when you put them away?
