Lancashire County Council has suspended the supply of all frozen processed beef products to schools, as a precaution, after its own scientific tests carried out on the products revealed traces of horsemeat in Halal burgers.
Earlier this month traces of equine DNA was found in cottage pie delivered to 47 schools in the county. The Halal beef burgers were available at four schools in the county.
All affected schools have been contacted and informed.
