Ratpacking is a term that means putting good product on top of the box with lesser quality product in the lower half of the box. When the box is first opened and inspected it looks good, however, after they work their way down the quality also goes down. This is something that was carried over from the old days and is very seldom done anymore, especially with the high quality packers that are in the market today. However, it used to be done with produce, bacon, portion cut steaks and chops. Today packers separate the number two product or inferior product and sell it at a reduced price rather than taking a chance on hurting their reputation.
