Perdigao in Brazil has posted a net loss in the fourth-quarter of 20 mln real (US$8.9 mln, €65 mln).
The net loss of 20 mln real compares with a profit of 98 mln real in the same period of 2007.
Sales jumped 59% to 3.07 bln real, led by a surge in dairy products and processed meat.
The jump in sales helped push earnings before interest, taxes, depreciation and amortization, a key measure of cash flow known as EBITDA, 93% higher to 465 mln real from the same period a year ago.
But despite the jump in sales, Perdigao had 318 mln real net financial loss in the quarter, caused by a weaker Brazilian currency.
