The Soil Association has been warned "not to repeat" claims implying their animal welfare standards are better than all other organic and non-organic schemes.

In a leaflet promoting organic farming, the SA claimed: "…FACT: Soil Association organic animal welfare standards are the best around…".

The SA provided an assessment by an independent expert, stating its welfare standards were higher than those of other organic farming groups.

However, the Advertising Standards Authority said that at the time when the leaflet was published, the advertisers had failed to show that they had valid independent documentary evidence to demonstrate their claim.
