Animal disease regionalization and its impact on tropical countries.

This paper reviews progress that has been made around the world in animal disease regionalization. Signatory countries of the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) and other free-trade associations are currently implementing regionalization, one of the cornerstone provisions of the Uruguay Round of the GATT and the World Trade Organization's (WTO) Sanitary and Phytosanitary Agreement. Regionalization allows countries to protect the health status of their animal herds and at the same time promote their animal and animal product export markets. The implementation of regionalization by importing countries affects export markets of tropical nations. Veterinary officials of tropical countries must give regionalization due priority such that import and export trade in animals and animal products is not hindered, and the public and animal herd health are protected.

Eradication of a new focus of Amblyomma variegatum in Puerto Rico.

In May 1992 an infestation with the tropical bont tick appeared in a small dairy heifer replacement herd in Camuy, Puerto Rico, a completely new site located near Puerto Rico's northwest coast. This finding occurred after some three years of no infestation in either Puerto Rico or the U.S. Virgin Islands and is not suspected of being associated with any previous infestations. The methods used to eradicate this tick include spray treatment at a two-week interval of all domestic livestock, with amitraz at 0.025% and permethrin at 0.055%. Dogs and chickens are also inspected. Owners are encouraged to reduce numbers of these species. All livestock on adjoining farms are inspected and treated on a frequent basis. There has been no evidence of any spread and the infestation is expected to be eliminated within 18 months.

Evaluation of the eradication program for Amblyomma variegatum (Acari:Ixodidae) on Puerto Rico.

A cooperative effort between the United States Department of Agriculture, Animal and Plant Health Inspection Service, Veterinary Services, the Agricultural Research Service, and the Department of Agriculture, Commonwealth Government of Puerto Rico has been successful in eradicating Amblyomma variegatum (Fabricius) from the islands of Puerto Rico and Vieques (an island municipality of Puerto Rico). Application of acaricides to livestock and dogs at 14-day intervals for an 18-month period eliminated foci of tick infestation on 188 farms in four different locations without additional aerial or ground treatment. Reasons for the success and some of the costs associated with the eradication program on Puerto Rico are presented.
