These cans are from Italy, and I know nothing of their regulations and safety standards. However, there are a couple of brands, Muir Glen and Bionaturae (from Italy), that specifically mention that their cans are lined, and the difference between the interior of their cans and the interior of cans from other brands is very obvious. Muir Glen and Bionaturae have a white, smooth interior while other brands appear to have an uncoated grey metal interior. I'm not saying that the other cans don't offer some protection from the acid - they must, I'm sure - but I just don't know the quality and durability of that protection.
I didn't notice a "use by" date, although it may have been on the can somewhere. Anyway, I have been trying to limit my tomato purchases to those in lined cans or in glass, at least until my comfort level about "unlined" cans has been raised. Still, I have been using a variety of San Marzano tomatoes to see which ones taste the best and provide the best value. It has been, overall, a wonderful experiment :lips: All the tomatoes, regardless of the can, have been far and away superior to any tomatoes canned or packed in the US.
