“…Examination of the six single-wrap muslin packs used to study depth of microbial contamination after 5 weeks of open-shelf storage showed penetration down to the fifth sponge in one pack. Two to seven of the nine surface sponges per pack examined were found to be contaminated.…”

“…The exterior surfaces of sterile packages become contaminated during storage. Several investigators have commented on the probability of transfer of this contamination to the contents when single-wrapped sterile packages are opened (2,5,12,15,18). Speers and Shooter (16) demonstrated that sequential unwrapping of doublewrapped packages substantially reduces contamination during removal of the sterile contents.…”

Microbial penetration of sterile packs was studied using single-wrap (two layers) muslin, double-wrap (four layers) muslin, and two-way crepe paper (single layer) to wrap 20 gauze sponges (2 by 2 inch). These packs were stored in the central sterile supply departments of two hospitals and processed for sterility at predetermined intervals. Microorganisms penetrated single-wrap muslin as early as 3 days and double-wrap muslin and single-wrap two-way crepe paper in 21 to 28 days stored in open shelves. The time required for microbial penetration was at least twice as long when closed cabinets were used. Single-wrap muslin packs stored in sealed, impervious plastic bags remained sterile for at least 9 months. All sterile materials in pervious wrappers should be handled as little as possible and then only with extreme care and caution. Closed cabinets offer more protection than open shelves, and single wrappers are not recommended.
