Firefighters at Brazil's Santos Port contained a blaze at two sugar warehouses operated by Cosan SA early on Monday, but the damage threatened to disrupt exports. The fire broke out at the sugar terminal's Warehouse X at 4:30 p.m. local time (1930 GMT) on Sunday, and 100 firefighters were on site Monday morning, said press representatives for Cosan, Brazil's biggest sugar producer. The cause of the fire was unknown. Last October, fire gutted the Santos export terminal of Brazil's largest sugar trader, Copersucar SA, quickly sending futures prices up 6 percent and causing the trader to issue force majeure to its clients. A spokesman at the Santos fire department said workers had finished controlling the fire and started an "aftermath" operation around 4 a.m. local time.
