Hands-free, pop-up, adhesive tape method for microbial sampling of meat surfaces

Microbial contamination of food is a concern to both food producers and consumers. For the food production industry surface sampling of foods is one of the simplest ways to monitor the microbial load. The objective of this experiment was to investigate the feasibility of using the less expensive and quicker Pop-up tape method instead of the conventional swab/rinse method for the microbial sampling of meat surfaces. An analyst can place the unit on the wrist and then use both hands to lay out all the necessary materials and take the sample with one hand. The Pop-up tape method was able to measure microbial loads up to 2.2 log CFU/cm(2) on meat surfaces. The conventional swab/rinse method was able to measure up to 8.3 log CFU/cm(2) on meat surfaces. The correlation coefficient (R) between the two methods was 0.91 (n=42). These data show that the Pop-up tape method is a viable alternative to other methods for estimating microbial surface contamination.
