We have a 2 lbs box of medjool dates. Very fancy. But it has been on the shelf for about 2 months. At first, when we split it, no visible bugs. Now we are seeing small white spots near the seed, salt grain sized.

Even with a good magnifying glass, I cannot discern if this is just sugar deposits developing (they are very sweet, and I am told that as they dry you sometimes get sugar), or if this is small bugs.

**How can you tell the difference between bugs, which would make the dates not kosher, and other small, white things, like sugar deposits?**
