Food labelling systems for animal products vary enormously in welfare information provided. Better labelling enables genuine consumer choice based on welfare.
Labelling gaps enable welfare-indifferent purchasing even by consumers who would choose differently with better information. The success of egg labelling - which drove significant market shift toward free-range - demonstrates that mandatory method of production labelling can change consumer behaviour at scale. Extending this model to meat, dairy, and fish requires political will and industry engagement that welfare advocates must continue to build.
