Holy cow! I just found out that the plastic in some mason jar lids are not BPA free! Which isn’t a big deal when storing dry stuff, but I like to make my own catsup and just started doing salad in a jar – so that is concerning! If you are a big mason jar user, such as myself, you might want to make sure that your jar lids are safe. And if not, no worries! You can order lids are are BPA free! Phew! Get yours now!
