Finland's largest dairy company, Valio has withdrawn a batch of milk-based infant formula and follow-on formula from shelves.
The sell-by date on the Tuuti products is May 12, 2017. Air may have been let into the formula due to a machine malfunction, which can lead to the liquid going off. A faulty product will smell and taste bad and may include clumps. The company says it must not be used.
The item should be returned for a refund at the store where it was purchased.
The milk products were produced at Valio's Turenki plant near Hämeenlinna.
The products affected by the recall are labelled with a best-by date of 12.5.201 and the following descriptions: Valio Tuuti 1 maitopohjainen äidinmaidonkorvike 500 ml UHT, Valio Tuuti 2 maitopohjainen vieroitusvalmiste 500 ml UHT and Valio Tuuti 2 maitopohjainen vieroitusvalmiste 1 l UHT.
Valio says it has informed wholesalers and retailers, who are removing the defective products from sale, and apologises for the mishap.
