Geronimo Alpaca was killed on the orders of the British DEFRA after a legal battle

Macdonald, whose legal efforts failed in court, insists that the test results were returned a false positive because the animal received a tuberculin vaccine before testing, which led to antibodies in its system. Before Geronimo was imported to England from New Zealand in 2017, he underwent several skin tests that gave negative results. Other alpacas traveling with Geronimo from New Zealand were negative, according to media reports.
