A case of bovine spongiform encephalopathy (BSE), also known as “mad cow disease”, has been confirmed on a farm in Aberdeenshire. The case was discovered before entering the human food chain, and Rural Affairs Minister Mairi Gougeon has said that all necessary measures have been taken to protect consumers.

Government policies are not doing enough to support the transition to a lower-carbon foods sector, according to a report by the Changing Markets Foundation. Specifically, the report argues in favour of policies to shift the food system away from animal agriculture and towards plant-based foods.

The Food and Agriculture Organisation of the United Nations has released the report “Transforming the livestock sector through the Sustainable Development Goals”, which examines how the livestock sector interacts with each of the Sustainable Development Goals, including synergies, trade-offs and complex interlinkages.

FCRN member Christopher Schlottmann and Jeff Sebo, both of New York University, have written a book discussing empirical, ethical, and social dimensions of food, animals, and the environment, providing both big picture and more detailed analysis, including updated statistics.

The Food and Agriculture Organisation of the United Nations has published guidelines for the assessment of nutrient flows and their associated environmental impacts in livestock supply chains. The guidelines are aimed at people and organisations who already have a good working knowledge of life cycle assessment of livestock systems, and are intended to promote consistency through defining calculation methods and data requirements.

In this study, researchers investigated the views of urban Brazilian citizens on dairy production. The study also explored the public’s awareness of and their views on the acceptability of four common husbandry practices: early cow-calf separation; zero-grazing; culling of the newborn male calf; and dehorning without pain mitigation. Their goal was to understand Brazilians’ concerns around and acceptance of dairy farming.

If the US were to shift to entirely grass-finished beef (vs. grain-finished), then the US cattle population would have to increase by 30% relative to today, because grass-fed cattle gain weight more slowly than those fattened in feedlots. Furthermore, existing pastures would have to become 40%-370% more productive to avoid converting more natural habitat to farmland or competition with human food supply. Methane emissions from the cattle’s digestive systems might increase by 43%, again because of slower growth rates.

Writing in the Guardian, Isabella Tree of Knepp Castle Estate argues that vegan diets ignore the potential of wildlife-friendly livestock grazing methods. Tree claims that not using anti-worming agents or antibiotics allows cow dung to feed various soil organisms, contributing to soil restoration and wildlife diversity.

New Zealand’s Parliamentary Commissioner for the Environment has released a report exploring how much and over what timescale the climate is affected by methane emissions from livestock. It focused on two questions. First,if methane emissions from livestock were held at current levels or followed business-as-usual trajectories, what would their contribution to future warming be? Second, what reduction in methane emissions from livestock would be needed so that they cause no additional contribution to warming?
