A Thai tuna processing factory has agreed to pay staff $1.3 million compensation for a litany of labor abuses, an official said on Tuesday, a rare victory for migrant workers in the kingdom's scandal-stricken seafood industry.

Hundreds of Myanmar laborers at Golden Prize Tuna Canning, a processing plant in Samut Sakhon that sells fish to markets around the globe, have spent months seeking compensation for exploitative working conditions.

Thailand is the world's third-largest seafood exporter, but the industry is plagued with rights abuses and fueled by trafficked labor from neighboring Myanmar and Cambodia.
