Mars must continue to listen to veggies

Annette Pinner Chief executive, The Vegetarian Society Sir; We welcome the steps that Mars UK has made in listening to consumers and keeping its Mars bar free from animal products. However, it is disappointing that there are still a number of other top brands such as Twix, Milky Way and Celebrations that remain off limits for vegetarians due to the presence of non-vegetarian whey ('Mars still using rennet in choc bars', The Grocer, 12 January, p5). It makes excellent business, as well as ethical sense, to make these brands available to the considerable buying power of the three million vegetarian consumers in the UK. We hope to continue a dialogue with Mars and to encourage the company to work towards using vegetarian whey and free-range rather than battery eggs in its products.
