Red Tractor has been given both barrels by Compassion in World Farming for its record in promoting animal welfare.
The kitemark was judged flat last for animal welfare in a study of humane assurance schemes by CIWF and the charity OneKind. The news comes just weeks after Red Tractor was attacked for its welfare standards by the BBC Countrywise programme - criticism Red Tractor said was unfair.
The Soil Association scored highest in the report, which rated schemes on criteria such as husbandry, handling, slaughter and breeding.
As well as group members of Red Tractor’s Assured Food Standards, other schemes rated included the Lion Code, Quality Meat Scotland and RSPCA Freedom Food.
“Red Tractor assures little more than compliance with minimum legislation,” said CIWF chief executive Philip Lymbery.
“When shopping for meat, milk and eggs from animals kept to higher welfare standards, it’s best to look for products labelled free range, organic or Freedom Food.”
