Sulfamethazine Residues in Hogs Dramatically Reduced After Team Effort by Veterinarians and Hog Producers
( 1989) Iowa State University Digital Repository

The detection of residues of sulfamethazine in hogs has been dramatically reduced as a result of a team effort involving the veterinary profession and the hog producing industry, the American Veterinary Medical Association (AVMA) reported. The dramatic drop in sulfamethazine residues came after the AVMA called for a temporary moratorium on use of the drug, a recommendation that was also made by the American Association of Swine Practitioners, the National Pork Producers Council, and the National Association of State Departments of Agriculture. AVMA in concen with its constituent the American Association of Swine Practitioners encourages food animal practitioners, working with their hog producing clients, to provide assistance in planning and evaluating drug use programs and in testing for residues at the farm before animals are sent to market. Swine practitioners have been using a Sulfa on Site (SOS) test to assure the absence of sulfa residues in pigs.

"The Iowa Cow War" Revisited
( 1989) Blomme, Robert ; Iowa State University Digital Repository

Bovine tuberculosis (TB) is almost nonexistent in the United States today due to an aggressive eradication effort begun earlier this century. Today we recognize the public health concerns associated with drinking milk from tubercular cows. However, those concerns were not so apparent at the early point of eradication efforts and our profession had an uphill battle carrying out the testing of cattle within the United States.

Lyme Disease: The Up and Coming Disease of the 1990's
( 1989) Noxon, James ; Johnson, Christine ; Iowa State University Digital Repository

A significant discovery came about in 1975 because of two observant housewives. One of them, a physician's wife, noticed a tendency towards the diagnosis of juvenile rheumatoid arthritis within her community. She knew that this disease did not normally occur in clusters and decided to report the observation to the State Health Department. The other housewife reported the unusual occurrence of arthritis occurring from young to old in four of her family members. Dr. Allen Steere, M.D., and co-workers decided to investigate their reports. They discovered that within three villages of Connecticut - Lyme, Old Lyme, and East Haddam - a high frequency of arthritis was reponed. The high frequency suggested that some infectious agent was involved. They also noticed that the majority of cases occurred in the summer or early fall. This seasonal tendency implied involvement of an arthropod vector. At that time, not much more was learned about the disease. However, because of its geographic tendency, the disease was appropriately named Lyme Disease (LD).

Editorial Notes
( 1989) Iowa State University Digital Repository

Through the media, and through speakers who have visited the veterinary college, I have had the opportunity to hear some of the tenets of animal rights activists, I have tried to listen with an intelligent and discerning ear since we seek, I presume, the same result, and that is the welfare of animals. Yet, somewhere along the line a problem with the methodology has developed.
