Tesco has launched an investigation after out of date baby milk was sold at a supermarket months after a carton from the same store made a toddler ill.

Andrew Campbell, 40, visited Tesco in Cranbrook Road, Barkingside, on Tuesday evening and purchased four cartons of Aptamil Follow-up Milk for his two-year-old son Ethan, one of which was 10 days out of date.

In January, Jerri Lee from Chigwell Row purchased milk that was 10 months out of date from the same store, leaving two-month-old daughter Milan sick for two days.

A spokeswoman for Tesco said: “We set ourselves very high standards for the safety and quality of our food.

"We are taking this matter very seriously and are urgently investigating how this has happened.

"We immediately checked our stock and found no other bottles on sale that were out of date, we are meeting Mr Campbell today to discuss his complaint.

"We will investigate this case and will keep him updated with the findings."
