That's the dilution and regrowth steps. You dilute plate and regrow with like 3 or 4 serial dilutions and grow on "clean" media a handful of times. Statistically speaking you can have such a dilution of whatever original toxins were present that it would be akin to a drop in the entire ocean. That won't take long at all.

Unless of course bacteria happen to be producing their own toxins which would cause problems. But it's not like we have identified bacterial toxins genetically and physically.
