Yes pickling cucumbers can be eaten raw and I find the raw pickling cucumbers to be crunchy and are delicious when eaten raw.
They're very tasty to eat when raw and are healthy for you as well.
Pickling cucumbers make for a great snack and a healthy snack too.
Although pickling cucumbers are mostly used for pickling and are not usually eaten raw the pickling cucumbers are edible to eat without pickling or cooking them.
I eat pickling cucumbers a lot and I have had no health issues.
