This report by UK sustainability consultancy 3Keel assesses the quantity, origin and certification status of soy in the supply chains of animal products sold by 11 European retailers (including UK supermarkets such as ALDI, Asda, Tesco and Sainsbury’s). It finds that 25% of this soy footprint was claimed to be free of deforestation - an increase over the previous year’s figure. The remaining 75% of the soy footprint is not claimed to meet any deforestation-free standard.

This research shows that global replacement of fish meal and fish oil in aquaculture feed with alternative feeds (including algae, bacteria, yeast and insects) could reduce aquaculture’s demand for forage fish while - depending on the specific mix of alternative feeds - maintaining feed efficiency and levels of omega 3 fatty acids in the farmed fish.

This report from UK food waste NGO Feedback and the Changing Markets Foundation assesses ten UK supermarkets on their aquaculture supply chain policies and practices, particularly regarding the use of wild fish as feed for farmed fish. Seven out of ten supermarkets scored less than 30%, with ALDI performing worst at 12% and Tesco performing best at 60%. The report finds that aquaculture operations for UK supermarkets consumed 2.5 times as much wild fish as the amount of farmed fish produced.

This report from the UK’s Eating Better alliance argues that replacing red meat with chicken is not a sustainable solution, and that growing consumption of poultry meat comes with costs to health, the environment, animal welfare and rural livelihoods. The report calls for reduced chicken consumption in the UK (to be replaced with plant proteins such as beans and nuts), and shifting away from intensive chicken farming towards “mixed and regenerative farming systems”.

This book addresses food waste from a variety of perspectives, including agriculture, food science, industrial ecology, history, economics, consumer behaviour, geography, theology, planning, sociology, and environmental policy.

This report from environmental campaign group Greenpeace UK examines how chicken consumption in the UK is linked to deforestation, through production of soy for animal feed. It sets out the “soya footprint” of supermarkets, fast food outlets and manufacturers, although figures are not available in all cases.

This report from the Food and Agriculture Organisation of the United Nations and the World Health Organisation examines how traces of veterinary drugs can pass through the food supply chain and affect either non-target animals or people who eat contaminated meat, eggs or milk. 

This book reviews different feed strategies for improving ruminant digestion and their effects on methane emissions, animal health and meat and milk quality.
