I saw the question on checking sugar snap peas. The answer is for peas grown on the US I live in England and sugar snap peas are not generally imported from the states. Are the European sugar snap peas considered as clean as. The US ones?
Regarding England, R’ Vaye writes in his sefer pg. 935 that they are occasionally infested, similar to peas from china and would have to be check likewise. It should be noted that this information is from his sefer, which is 10 years old. I don’t know if things have changed since then or not.
