I've noticed letters after the expiration date on milk bag tags.
Product: Neilson Milk Bag
Location: Canada
Please see the photos below. Sometimes there are letters after the expiration date and sometimes not. You can see the letters C, E and F after the expiration date in the example tags.
What is the meaning of the letters after the expiration date?
I've searched online and Canadian Food Inspection Agency website but couldn't find anything relevant.
I haven't noticed this in other products but the milk bag tags might be more noticeable. There are also extra numbers in some tags.
