Tourists watch a tigress with piglets at the Sri Racha tiger zoo, in Chonburi province southeast of Bangkok, 18 November 2004. The world’s largest tiger breeding centre in Thailand reopened 18 November at the end of a bird flu outbreak that left 83 animals dead. The outbreak of the deadly H5N1 virus was detected 14 October and believed to have been caused by some of the zoo’s 441 tigers eating raw infected chickens.
