BRF, the Brazil-based protein group, is to set up a plant in Seropédica, west of Rio de Janeiro.
The company said the 11,000 square metre facility will manufacture meat products, although it did not specify which lines would be made there despite questions from just-food.
Some BRL180m will be spent on the factory, which will be BRF's 36th plant in Brazil. The plant will create around 400 jobs.
"Despite the extremely challenging economic scenario, we identified an excellent opportunity in Rio de Janeiro," BRF CEO Pedro Faria said.
In July, reports in Brazil claimed BRF was set to invest BRL1.1bn (US$285.7m) in boosting its production of pigs and poultry in Brazil, although the company declined to comment.
BRF is scheduled to report its third-quarter results tomorrow (30 October). In the second quarter, BRF's domestic business saw its EBIT drop 3.9% to BRL389m despite an 8% increase in sales to BRL3.96bn. Volumes dipped but a 15% increase in processed food sales helped its revenue.
