I realize that SE has their weekly newsbites, and several of these have been posted before, but I felt this piece from Bloomberg was worthwhile. (Not the greatest source, and it eventually starts sounding like a tabloid, but still.)
It's a useful summary of several occurances of food poisoning and deaths caused by American and Mexican farms/food processing plants that have been glossed over by third-party, i.e. private, for-profit auditing companies. Basic coverage of FDA issues, workers' rights, economics, etc.
