Puerto Rico has banned the sale of meat from Vieques Island pending the results of toxic substance testing. Two-thirds of the 51-acre island are used for U.S. Navy training exercises. Officials are unsure how much meat is produced from livestock that graze on Vieques, which is just east of Puerto Rico's main island. Results of the tests are expected in two to four weeks.

Opponents of the Vieques bombing range claim that the military exercises conducted there have adversely affected the health of many of the island's residents. Recently, President Bush announced that the Navy would stop training on the island in 2003.
