Contact Surfaces

ABSTRACTContamination of food contact surfaces with pathogens is considered an important vehicle for the indirect transmission of food-borne diseases. Five different cleaning cloths were assessed for the ability to remove viruses from food contact surfaces (stainless steel surface and nonporous solid surface) and to transfer viruses back to these surfaces. Cleaning cloths evaluated include two different cellulose/cotton cloths, one microfiber cloth, one nonwoven cloth, and one cotton terry bar towel. Four viral surrogates (murine norovirus [MNV], feline calicivirus [FCV], bacteriophages PRD1 and MS2) were included. Removal of FCV from stainless steel was significantly greater (P≤ 0.05) than that from nonporous solid surface, and overall removal of MNV from both surfaces was significantly less (P≤ 0.05) than that of FCV and PRD1. Additionally, the terry towel removed significantly fewer total viruses (P≤ 0.05) than the microfiber and one of the cotton/cellulose cloths. The cleaning cloth experiments were repeated with human norovirus. For transfer of viruses from cloth to surface, both cellulose/cotton cloths and microfiber transferred an average of 3.4 and 8.5 total PFU, respectively, to both surfaces, and the amounts transferred were significantly different (P≤ 0.05) from those for the nonwoven cloth and terry towel (309 and 331 total PFU, respectively). There was no statistically significant difference (P> 0.05) in the amount of virus transfer between surfaces. These data indicate that while the cleaning cloths assessed here can remove viruses from surfaces, some cloths may also transfer a significant amount of viruses back to food contact surfaces.

Package Materials

The ability of the cigarette beetle, Lasioderma serricorne (F.) (Coleoptera: Anobiidae), to infest wheat flour under packaged and unpackaged conditions was investigated in the laboratory at 27 ± 2°C and 75% ± 5% relative humidity. Five common packaging materials, namely, vacuum plastic bags, kraft paper bags, nonwoven cloth bags, aluminum foil bags, and woven plastic bags, were investigated. Adults and eggs of L. serricorne were released on different packaged wheat flour or on unpackaged wheat flour, and infestation levels (number of live adults and larvae) were determined after 45 days. When adults were released on wheat flour, the infestation degree varied depending on the package materials. The highest infestation was observed in refined wheat flour packaged in nonwoven cloth bags. With wheat flour packaged in kraft paper bags exposed to adults or eggs, there was no insect infestation or insect infestation was negligible (mean population, <1.3). With wheat flour packaged in aluminum foil bags and vacuum plastic bags exposed to adults or eggs, there was no insect infestation. Damage to the packaging materials along the folds or edges was found in nonwoven cloth bags and woven plastic bags. Therefore, both aluminum foil and plastic bags had the greatest resistance to package invasion by L. serricorne.

Support Decision Making

Moist/wet materials stored after autoclaving are considered contaminated and not recommended for use. This study evaluates the maintenance of sterility in moist/wet material after being submitted to steam sterilization and stored for a period of 30 days. Aiming to support decision-making in emergency situations, 40 surgical boxes packed in nonwoven cloth covering Spunbound, Metblouwn, Spunbound (SMS): half (the experimental group) were placed in an autoclave but the drying phase was interrupted, yielding moist/wet materials and the other half (the negative control group) underwent the complete cycle. The external parts of each surgical box were deliberately contaminated with Serratia marcescens and subsequently stored for 30 days. After this period, the boxes' contents were submitted to sterility tests and no growth was observed. The presence of moisture inside the surgical boxes did not interfere with maintaining their sterility.
