Thanks for the info Dagny. I need to get some. While I'm not in a high risk area, they probably are a good thing to have in the times we live in.

Re pets, probably highly unlikely there would be any allergic reactions and if you were in the situation to need them, there wouldn't be any other choice.

I've used trace mineral and iodized salt blocks for years with horses and my dogs have licked them in the fields with no harm.
