I would bet Dollars to Dounuts that the bulk of the illnesses were not a result of under cooked turkey but Cross contamination. The people that are big fans of ground poultry, use it as a Healthy alternative to ground beef. Along the same line, a higher consumtion of salad is found among the most health conscious. Mix up a batch of Turkey Meatloaf, followed by a tossed Salad without proper sanitation and you have a week of misery or WORSE. Some people just don't THINK!
In the first restaurant in which I was hired to manage, the kitchen was a disaster waiting to happen. I was the first employee hired in this Diner that was Servsafe Certified. Day 1, I went into the walk-in to find a case of iced Whole Chickens on a top shelf directly over bus pans of freshly sliced Lunch Meats and sliced Tomatoes! When I brought it to the attention of the owner, I got a bewildered, " what, that's a problem? It's on a Sheet Pan!", then a argument over why I wanted to Toss 5 pounds of Cold Cuts and a container of Tomatoes. Scary stuff and a week of OJTin sanitation with the entire kitchen staff...JJ
