Yes, Dr. Holley mentioned pooling a lot of data.
He got beyond the pool and actually was in touch with many of the public health jurisdictions across the country to find out where outbreaks occurred, whether it was in a school or hospital or church dinner. He found out what the food was, whether it was wieners or potato salad, and the number of people who were ill, that kind of data, which he published. I think it's in the Canadian Institute of Food Science and Technology Journal. So it is published. Actually, I used this data in teaching, when I was at the University of Guelph, to show what the hazards were, what kinds of foods had the highest hazards, what kinds of organisms, that type of thing.
