This study explores the pig-raising practices of Chinese migrants in Los Angeles Chinatown during the Chinese Exclusion Era. Chinese butcher shops sold pork meat, and previous research indicates that they likely sold the more profitable parts outside of Chinatown for additional income while consuming cheaper cuts themselves. Using dental calculus analysis and archival research, this study further explores how Chinatown residents relied on pork to thrive in an anti-Chinese environment. Dental calculus results suggest that Chinese migrants raised their own pigs with food waste and by-products from rice fields; this pork was then sold to meat markets or consumed within the community. The analysis of immigration records indicates that Chinese butcher shops provided employment opportunities as well as housing, banking, and immigration support for Chinese migrants. Pig raising, therefore, not only supplied a source of meat for Chinese migrants but also supported a range of social and financial services for a marginalized group that faced everyday discrimination from dominant society. Overall, this study traces the labor and networks that small businesses in the late nineteenth and early twentieth centuries needed to source and distribute pork, and it highlights how a Chinese diasporic community developed a pork production system to resist racism.
