Meat

Objective
The objective of this study was to determine the antimicrobial efficacy of a new laminated microchip device -3RN21- on the indigenous (natural) microflora of fresh meat stored at room temperature for 24 hours.

Background
Determine the antimicrobial effect of the laminated microchip device --3RN21- on the indigenous (natural) microflora of fresh meat stored at room temperature for 24 hours.

Materials and Methods
A. Test Product
Laminated microchip devices coded 3RN21 were provided The laminated microchip device composed of 21 individual microchip units. Two devices were attached together facing opposite directions horizontally according to the manufacturer’s instructions.

B. Meat Sample Preparation
Fresh ground beef sample was divided into five portions. Each portion was placed in a sterile Whirl-Pak bag. One portion served as negative control (untreated). The second portion (treatment) was placed in the bag in a rectangular shape with 0.3 cm in thickness, 10 cm in width and 10 cm in length. The third portion (treatment) was placed in the bag in a rectangular shape with 1.0 cm in thickness, 10 cm in width and 10 cm in length. The fourth portion (treatment) was placed in the bag in a rectangular shape with 1.5 cm in thickness, 10 cm in width and 10 cm in length. The fifth portion (treatment) was placed in the bag in a rectangular shape with 2.5 cm in thickness, 10 cm in width and 10 cm in length. The laminated microchip devices were paced on top of the samples. Samples were analyzed for total aerobic counts initially and after 24 hours storage at room temperature. The method of analysis is outlined in the following table.
