Does Iodized salt have to be labelled as such?

How do I know if I'm dealing with iodized salt or not? If iodine is added, is the salt reaquired to be labeled as such? Sometimes I see a salt label that says "does not contain iodine". Sometimes I see a label that says "iodized salt". Sometimes I see one that lists the ingredients as salt and iodine. Other times I see one that says the ingredients are "sea salt" but it does NOT say it does or does not contain iodine. I am pretty sure that pickling salt is iodine free, but my pickling salt doesn't say this, it just says "salt". Is sea salt naturally iodine free? I'm getting into cheese-making and so knowing the difference will change my outcomes.

  1. Salt with iodine added to it will have to have it marked somewhere on the label.

    Some salts, sea salts especially, may have naturally-occurring iodine within them that is not required to be separately labeled as such.

    Salt where the processor has verified does not contain iodine will be labeled as "Iodine free" or "does not contain iodine" for those who need to avoid it for medical reasons.

    1. Sea salt can have varying levels of iodine. It depends on where it's harvested from. If you have a recipe that requires an iodine free salt, it's best to stick to pure non iodized table salt.

      1. pickling salt is iodine-free. that's why your pickling salt box just says "salt".
