Probability is high that you are safe. Peas (and almost every other legume, vegetable and fruit) in 2018 are genetically engineered to be safe to eat directly after packaging. Also, they most likely have been sprayed with fungicides and pesticides. In triplicate, sulfuric acid (the stuff in your stomach) is so strong that it will destroy almost every other thing the first two didn't already eliminate. I'd bet you'll be fine.
