Retailers in the UK are rationing sales of powdered baby milk because of a surge in demand in China.
According to BBC reports, Danone, the manufacturer of Aptamil and Cow and Gate baby milk powder, said most supermarkets were introducing a restriction of two cans per customer.
The company said the limit was to prevent some individuals from bulk-buying baby milk for "'nofficial exports'.
Retailers are also understood to be capping sales of Nestle's SMA milk, despite the company saying there were no stock shortages.
Danone said in a statement: "We understand that the increased demand is being fuelled by unofficial exports to China to satisfy the needs of parents who want Western brands for their babies. We would like to apologise to parents for any inconvenience caused by this limit. We know that most parents only buy one pack at a time, so we hope that the impact of this limit on UK parents will be minimal.'
Supermarkets Asda, Sainsbury's, Tesco and Morrisons said the purchase of certain brands would be limited to two units per customer per day.
