I picked one of our radishes today and I scrubbed and scrubbed and I could still see dirt in the crevices. ?

Hoe do stores clean theirs? We planted lots of veggies but I don't want to eat them if I can't clean them properly. Will bird droppings cause salmonella? Why are there earwigs in my lettuce?

How do I get rid of them organically. Especiall the earrings which sicken me
