As usual, Dr. Cook has written another "page-turner." I couldn't put the book down. After "Chromosome 6," I vowed that I would not read another of his books, but I read "Toxin" anyway. His diatribe against the beef industry is right off Oprah and his descriptions of meat packing are right out of PETA fund-raising material: it sounds disgusting, but it didn't convince me go give up beef. Pass me a burger! On top of all this, the ending was very weak.
