Recently my wife bought a 24-pack of 12oz Gatorade Performance 02 bottles (Strawberry, Berries and Grape) from Costco. The outside plastic covering the pack had the OU symbol. When I took the first bottle out I looked for the OU symbol and it had it. However the next bottle (of the same flavor) had a slightly different label and no OU. I removed all bottles from the pack and found that of the 8 Grape bottles in the pack, 4 did NOT have the OU symbol.
I am not sure if this is just a labeling error or some more serious issue. I am just posting this for th tzibbur to be watchful.
