I've recently seen a sticker on apples from Canada in a market that starts with the number 3. I read everyone's blurb on this on this site and nowhere is the number 3 with I think 3 or 4 more number after it mentioned. I asked the produce man at that store what it meant and he too didn't know. Do you? I searched all over the web for this revelation to no avail. Thanks for any info on this. Cheryl
