DARLING INTERNATIONAL ANNOUNCES
FIRST QUARTER 2006 RESULTS

        Irving, Texas, May 11, 2006:   Darling International Inc. (AMEX: DAR) today reported sales and earnings for the first quarter ended April 1, 2006.

        For the first quarter 2006, the Company's net sales were $76.4 million as compared to $71.4 million for the first quarter 2005. Increases in raw material supplies and a higher volume of purchased finished product for resale accounted for the majority of the $5.0 million increase.

        Net income for the first quarter 2006 declined to $0.4 million, or $0.01 per share, as compared to net income of $0.9 million, or $0.01 per share, for the 2005 comparable period. The $0.5 million decrease in net income for the first quarter 2006 resulted primarily from (i) higher energy prices for natural gas and diesel fuel, (ii) increased operating expenses related to the start-up of the Fresno, California modernization project, and (iii) higher legal expenses.

        Darling International Inc. Chairman and Chief Executive Officer Randall Stuewe said, "Higher energy costs and continued restrictions on the export of our products continued to weigh on our earnings during the first quarter. Our performance was also impacted by increased costs related to the modernization of the Fresno, California project and higher legal expenses related to matters in which the Company seeks affirmative relief."
