My mom just called me to let me know the FDA has issued a warning about some cases of botulism reported due to bad carrot juice. And wouldn't you know it? The recalled product is what I've been drinking - stuff from Bolthouse Farms. Ug!
The full warning is here: http://www.fda.gov/bbs/topics/NEWS/2006/NEW01475.html.
Addendum: I should clarify that it is suspected that the botulism poisoning cases are the result of "temperature abused" bottles of the juice - i.e. the stuff wasn't properly refrigerated. But, it does seem a bit concerning that two of the cases occurred within a day of each.
