Transmission of Livestock Diseases to Humans For decades now, death and disease have driven the advancement of technology. Thanks to advances in science, many diseases have been made obsolete and many others are increasingly closer to defeat. However, despite all the diseases we have defeated, more and more are appearing. And old diseases that we thought we were protected from have made a comeback. An example of this is foot and mouth disease. “Since 1930 the United States of America has prohibited the importation of fresh, refrigerated, or frozen livestock and meat from countries where rinderpest or foot-and-mouth disease exists” (Publication 1343, 49). The United States is considered a foot-and-mouth disease-free country. However, this does not mean that we have not taken action in trying to eliminate foot and mouth disease in other countries. In 1966, a joint Argentina-United States commission on foot-and-mouth disease was held. In a report on this meeting it was stated that "The conditions under which foot-and-mouth disease (FMD) virus survives in animal tissues have long been known issues of fundamental interest to all officials interested in the prevention and control of the disease" ( Publication 1343, 3). A CENTO seminar on viral diseases was held from 12 to 17 June 1972 in Istanbul, Turkey. This seminar had a special emphasis on foot-and-mouth disease and rinderpest-like diseases discussion of disease free zones and regulations for these zones (Girard 93) Some of the regulations established included complete control of movements of domestic livestock, traffic of people to and from an area that has been quarantined should be limited. and, if an epidemic occurs, no animals can be exported, all animals present ......asis vol. 7, number 4.
