Food labelling is a very. big. issue. Some labels matter a lot. Some matter less. Some labels are required by law. Some are not. Some labels have clear, precise, even regulated meanings. Others are purely a matter of convention, and others mean very little at all.
One of the most important kinds of labels, naturally, are ones mandated by regulations. But what those regulations require, and what the labels mean, is not always clear. So some of you will be interested to see this FDA Food Labeling Requirements Ebook, published by label company supplier Foodpackaginglabels.net. I haven’t read the book yet, and can’t attest to its accuracy, etc., but it looks useful.
