Three children are in hospital after a suspected E. coli outbreak in County Durham and Teesside.
Public Health England (PHE) is warning people to not eat any cold pre-cooked meats and savouries bought since 25 June from Robinsons butchers in Wingate and Billingham.
Seven confirmed cases and one suspected one have been reported in the past week in both adults and children, PHE said.
A spokesman for Robinsons said it was discarding all ready to eat food.
