Urban councillors yesterday urged health officials to conduct quicker livestock inspections as abattoirs, disposing of pig offal by the tonne, are straining manpower resources. Members of the public health select committee made the call after inspecting Cheung Sha Wan abattoir where offal was being destroyed due to the latest food scare. The banned drug clenbuterol, which is potentially fatal to humans, was found in pigs' innards last month when 11 people fell ill after eating pig's lung soup. Traders have been told by health officials to suspend sales of offal. The drug, used by some farmers to promote leaner meat, which in turn will fetch higher prices, can cause palpitations. Department of Health officers have since taken samples from discarded offal at abattoirs for testing. The offal, popular in soup and other dishes, is then destroyed. Committee chairman Joseph Chan Yuek-sut said a quick test must be implemented as soon as possible because the mass disposal was wasting staff and food resources. 'We have to establish a checkpoint which will allow us to test the livestock before they reach the abattoir,' Mr Chan said. 'A border check would help to ensure that livestock reaching the abattoir is in good condition and healthy for human consumption - anything testing positive could be quarantined.'
