In May 2015, the company said that they will stop serving milk from farms in Gloucestershire's badger cull areas. On 29 May 2015, the company said: "Caffè Nero has instructed its partners supplying to stores which are situated around the cull zone areas to supply milk from farms outside of the zone. On 7 July 2015, rats were videoed scurrying along the floor and counter in their Donegall Square West unit in Belfast, despite having previously been awarded a four out of possible five star rating by inspectors from Belfast City Council. Having been notified of the incident, the store was closed for a full investigation and has subsequently reopened; the source of the infestation was an adjacent disused building. A 2017 study by the BBC found trace amounts of faecal bacteria in Caffè Nero's iced drinks, alongside those of Starbucks and Costa Coffee.
