I remember something about injecting toxins into off-the-shelf medicine (maybe Aspirin?). Perhaps that's what you're thinking of?

Apparently this was longer ago than I thought: 1986. Here's a link: http://www.nytimes.com/1986/09/19/us/batch-of-rite-aid-aspir...

No, that was way long ago, and may have been inspired by the tylenol stuff before it in some way.

No... I just can't find the story I'm thinking about now. All references to restaurant food poisoning are now coming up with that dec 2010 incident. :/
