In the produce aisle you may notice stickers on produce with a 4 digit code. 5 digit codes that begin with 9 indicate organic and those that begin with 8 note GMO foods. Something to be aware of when shopping for produce. For more information check out this post at Enviroblog. A handy thing from the post is a link to all the codes for produce. You can search and see what each code is so you can see exactly what you are getting.
