Help deciphering elemental analysis of worm castings?

Hey, i recently found an add in the paper for worm castings at $4 usd per 50 pounds. It seemed an amazing deal so i bought $20 worth. The thing is, its not worm castings from earth worms, but from some other type of worm that is raised to be sold as lizard food. They look like a big meal worm or butter worm, but i really don't know what type it is, and they feed it chicken feed. I went to the local extension office and got the levels tested to determine its elemental makeup. Any help with what may be good or bad about this stuff would be appreciated greatly. I don't want to use it if it could be bad for the plants in any way. Also, does the fact that chicken feed is used to feed the worms cause any kind of problems or create any hazards if i were to want to use the castings to amend soil that i was growing food in?

Thanks, here's the results:
