Tesco expects the issue to be resolved, and operations back to normal, by next week. Our sister site, The Grocer, reported earlier this week that a number of British retailers had been left short of Danone brand yogurt as a result of "a major disruption" to the supply chain - caused by the transfer of the products to a new distribution centre in Hertfordshire operated by dairy processor, Arla Foods UK. Arla, which provides third-party warehouse storage in the UK for Danone yogurt brands, confirmed that a "systems interface error" occurred at the centre.
