Bees on raisins?

So recently, I started drying raisin in the sun. That's going fine and dandy. However, I've noticed an accumulation of bees around them as they dry. They eat the inside (or at least as far in as they can reach), and go nuts for the grapes. This doesn't bother me, I love bees. But one concern is that there will be disease spread through their juicy searches. I know they're not flies, so they're probably not going anywhere near my dogs' poop, but the worry is still there. Is this irrational?

They are not going to be carrying anything that will harm people, if that is what you are getting at. However, fruit juices are far from ideal food for bees. Unlike nectar, fruit juice contains considerable amounts of plant fibre which is indigestible to bees. In large amounts it can cause dysentery. This is also why, when bees need to be fed sugar, you must always use refined white sugar rather than dark sugars. The dark sugars cannot be digested.

Just because you are seeing bees and not flies, doesn't mean that there aren't flies visiting the fruits...
If you are worried, maybe some insect screening over the top would put your mind at ease.

Do you think washing them would be sufficient enough for cleaning the already dry ones?
