Legislation has been the main policy approach for protecting the welfa
re of farm animals, The use of legislation raises issues such as whose
preferences the legislation reflects and whether the preferences of s
ome people in society should constrain the food consumption choices of
others, The paper outlines a survey in Great Britain which sought to
measure people's willingness to pay to support legislation to ban the
use of battery cages for egg production in the European Union (EU). It
discusses the implications of the survey findings for animal welfare
and food policy. It concludes that legislation which constrains food c
onsumption choices may be justified where there are significant negati
ve animal welfare externalities as a result of livestock product consu
mption. However, the combination of legislation and producer subsidies
may provide an appropriate policy which improves animal welfare witho
ut directly constraining food consumption choice and could help to ach
ieve other policy aims regarding agriculture in the EU. (C) 1997 Elsev
