Birds Eye has withdrawn three beef ready meals from supermarkets in the UK and Ireland as a precaution after horse DNA was found in a product in Belgium.

Birds Eye said its chili con carne had tested positive for 2% horse DNA.

The news comes as the Food Standards Agency prepares to announce results of its latest tests into the contamination of processed beef products.

The tests - on a range of ready meals - are likely to indicate whether the horse meat scandal has been contained.
