Lettuce bugs?

I have these black dots all over my lettuce. They don’t appear to be bugs and can be hosed off. Do you have any idea on what they can be? How to treat them?

This could very well be frass (droppings) left behind from caterpillars and the like. If you wash it well, it is still fine to eat, although it doesn’t sound pleasant.
