Livestock welfare standards vary dramatically between countries, creating welfare disparities and trade complications in the global food system.
Global welfare disparities mean that animals raised for food experience vastly different conditions depending on geography. Trade in animal products can undermine welfare improvements when products from lower-standard countries compete with those from higher-standard regions. International harmonization of standards would improve welfare globally but faces resistance from economic and sovereignty arguments. The trend is toward improvement, with many countries adopting stronger protections over time.
