A Florida fresh citrus packing efficiency cost study for the 1995-96 season was conducted from January 1997 to August 1997. A total of 14 commercial citrus packers--8 from the Interior region and 6 from the Indian River area--provided packing cost data for the study. These 14 packers accounted for 26.9% of the total Florida fresh packed citrus during the season reported. A summary of the estimated average comparative packing costs per 4/5 bushel carton for the Interior and Indian River regions is presented. The average cost per 4/5 carton for the Interior and Indian River was $3 .53 and $4.10, respectively. The statewide average cost for all packers was $3. 7 4 per 4/5 carton.
