From a reader who knows a lot about seeds.... some words about seed safety.

Seed Analysis and Seed Testing

Seed analysis pertains to the testing of seed that is to be sold through commercial channels to farmers, gardeners, and other seed growers. Every bag of seed that is sold has to have a "seed label" attached to it.

Because of this, each seed lot being sold has to be analyzed for certain physical and quality aspects. Each seed company has their own seed lab that does these tests and most states have a state seed laboratory that does these tests for regulatory purposes.
