July 7, 1974 Derr Dr. Kehoe: Perhaps you could help me with ^problem or refer this letter to someone who could. I h~d a litter of Greet Dane pups that the Vet said was showing clinical signs of lead poisoning. The Vet attempted to locate the source of the problem. The only thing the Vet md I even suspect -t this point was anew bag of "Thrivetts" deg food which the litter had been recently introduced to. D-lare Labs analyzed the dog food -nd found it to have a lead content of 0.4 ppm. The Vet or I have been unable to locate any information on the acceptable amount of lead in feedstuffs". We would appreciate -my information you mignt have on this subject or any suggestions aS to where to find the inform- tion. Thark you ,7 Charles E.
