Global food supply chains span multiple countries and regulatory environments, creating welfare gaps between production standards in exporting countries and expectations of consumers in importing markets.
Global food supply chain welfare is a regulatory and traceability challenge as much as a farming challenge. Consumers in high-income countries with strong domestic welfare standards routinely purchase imported animal products produced under conditions that would be illegal domestically. This regulatory arbitrage creates economic pressure against welfare improvement: producers who invest in welfare improvements in countries with strong standards compete against cheaper imports from countries without them. The solution requires both domestic import standards that apply to animal products (as the UK's Animal Welfare (Kept Animals) Bill has attempted) and international trade agreements that prevent downward harmonization of welfare standards. Without these, domestic welfare reform may primarily shift production offshore without reducing aggregate animal suffering.
