THE Advertising Standards Agency (ASA) has ruled that a poster by the vegan advocacy charity Viva! linking milk to cancer is unsubstantiated, misleading and must not appear again.

The poster, displayed on buses in Bristol last September, featured an image of a cow's udder and included the claims "Some dairy industry facts we bet you don't know .... Most cows are pregnant when milking. That's why milk contains 35 hormones, including oestrogen .... some of these are linked to cancer. Milk is for babies , so let Viva! wean you off the teat!".

Two complainants, who believed the claim "milk contains 35 hormones, including oestrogen .... some of these are linked to cancer" implied that drinking cow's milk could cause cancer, challenged whether the implied claim was misleading and could be substantiated.

In response, Viva! said the claim referred to hormones that were naturally occurring in cow's milk, which increased during pregnancy and were essential for calf development. The claim did not refer to hormone treatments or artificial hormones.

They highlighted that the ad stated the hormones were "linked to" cancer, rather than that they "caused" cancer.

In making its ruling that the advert must not appear again in the form complained about the ASA concluded the claim "milk contains 35 hormones, including oestrogen .... some of these are linked to cancer" as it would be understood by consumers to mean that due to the presence of hormones, drinking cow's milk could increase a person's risk of developing cancer, had not been substantiated and was therefore misleading.
