I had conducted some disc diffusion tests with E.coli and S.epidermidis.
Now, I wanna dispose these petri dishes and was wondering the correct way to do it. Many websites mention adding bleach to the agar and disposing them in biohazardous waste bags right away.
I've decided to do the same. But, the lid for all the petri dishes I have are very loose. If I simply dispose the petri dishes in waste bags, I think that the lids are gonna come off and the bacteria may infect the waste bags.
Should I seal the petri dish with some tape like a parafilm so the lids won't come off or is it not a problem that the bacteria may come out onto the waste bags?
(No websites mention the issue of loose lids while disposing, so I wonder if this is a problem at all)
