Is a spore strip dangerous?
Although the Bacillus spores on a spore strip are typically considered non-pathogenic to humans, care should still be taken when handling them. Do not open or tear the blue glassine envelope or you will expose yourself to the spores and also invalidate the test. If you need to discard unused spore strips, sterilize them for 30 minutes in an autoclave at 121° C or two hours in a hot air oven at 160° C before throwing them away.
