UK supermarket giant Tesco has withdrawn chickens from its shelves that wrongly carry the "freedom food" label. The label, launched as an RSPCA (Royal Society for the Prevention of Cruelty to Animals) initiative, is meant to guarantee to consumers that the animals they eat were reared according to certain welfare standards. It may only be used under licence from the society, but routine checks exposed the false-labelling breach at a major Tesco supplier.
