(Updates with details, share price) LONDON, Dec 14 (Reuters) - Own-brand frozen meals from Asda <WMT.N>, Birds Eye and Sainsbury's <SBRY.L> containing rice are being recalled due to a possible contamination from small glass fragments, Britain's Food Standards Agency said on Thursday. The affected products have all been manufacturered by Rye Valley Foods, owned by Kerry Group <KYGa.I>, in Ireland. Consumers who may have bought any frozen ready-to-eat meals that contain rice from these retailers are advised to take the product back to the store. A full list of the affected products are published on the agency's Web site www.food.gov.uk/news/newsarchive/2006/dec/frozen. The list comprises 20 Asda products, four from privately-owned Birds Eye and four from Sainsbury's. When Cadbury Schweppes <CBRY.L> was forced to recall more than 1 million chocolate bars in Britain and Ireland this year because of minute traces of salmonella in some of its products, it cost it 30 million pounds. Shares in Sainsbury's ended up 0.5 percent at 405-3/4 pence.
