Batches of human breast milk have been recalled, amid fears regarding to the amount of lead that some may contain.
Executives at the Food Standards Agency have launched an investigation into the milk-based products created by NeoKare Nutrition Limited - which the FSA understand contain above average levels of the metal.
The products, which had been supplied to 13 NHS hospitals have since been urgently recalled. Of the total number of hospitals affected, seven are known to have used the products - six in England and the other in Wales.
