I'm making my own bokashi for the first time and we ordered a bottle of EM-1 Microbial Inoculant. It says right on the label not to store in direct sunlight, but like a goof, I accidentally set it on a table in my kitchen that gets a lot of sun. It only sat there for about a day before we realized and moved it to a dark cupboard.

Would this be enough to damage the EM-1 or significantly reduce the bacteria count? Is there a way to test the EM-1 to see if it is still good?

Please help. Thank you!
