Before being recognized as a town, Jesuits and Spanish, Italian and Basque immigrants had created communities in the area that would become La Teja. Buying Jesuit land, the British entrepreneur
Samuel Fisher Lafone created a meat curing plant in the area, and with the help of the city planned 122 city blocks in the area. These communities created an industrial working-class neighborhood strongly identified with militancy and solidarity found in urban politics in the region. As workers built up housing in the area, the native marsh was frequently backfilled with industrial and construction waste that was easily available. Both formal and informal settlements in the neighborhood were built on reclaimed, and sometimes contaminated, industrial sites. In the early 2000s, several local children were identified to have high lead exposure. After investigation, doctors and public health officials discovered broad contamination of the community. In response, the community formed what anthropologist Daniel Renfrew called "the first environmental justice movement in Uruguay", embodied in the organization
Comisión Vivir sin Plomo (Commission for a Life Without Lead). The group was led by
Carlos Pilo, a local militant community organizer. The campaign led by the community resulted in a widespread public health awareness of lead contamination and eventual regulation in the country. == Economy ==
