There are a number of vegetable sources of nitr{a,i}tes as well. A stick of celery has more (potassium IIRC) nitrate than a typical piece of salami has (sodium) nitrate. This is why celery juice is an ingredient in so-called "nitrate-free" cured products. They're not actually nitrate-free, they just use celery juice as a source instead of adding a pure powder, so they don't have to list "sodium nitrate" explicitly. https://www.mcgill.ca/oss/article/food/celery-juice-viable-alternative-nitrites-cured-meats https://www.mcgill.ca/oss/article/food/celery-juice-viable-a...
