 The Mount Pleasant facility consists of approximately 20 individual processing cells that are separated from one another and are set up so that they could operate as individual meat slicing facilities . Before anti @-@ microbial flooring was poured , the cells were erected with stainless steel anti @-@ microbial walls that are built into the floor . Each processing cell has independent refrigeration and drainage systems . The refrigeration systems filter the cell 's air and maintain positive air pressure at 38 ° F ( 3 ° C ) , and the drainage systems are sealed off and flooded with sanitizers nightly .
