Health Advice

I throw myself upon the wisdom of my fellow foodreporters. I bought a new jar of Horlick's at the C-Town - British malt mix for your milk, it has a bunch of vitamins, and makes for a fun nighttime ritual. More info here. Anyways, I had not opened it yet, and the protective seal under the cap ("do not use if seal is punctured" is more or less what it says) was punctured. Should I dismiss this as an unfortunate accident? Or should I fall on the side of caution, and write this jar off as a loss? Remember, there's no realistic way for the seal to have been punctured without someone having taken the lid off, so either this happened at the factory, or some degree of foul play was involved. Please help!
