Charm Peel Plate Microbial Test

Peel Plate bacterial tests are simplified culture methods for detecting micro-organisms. Tests are available for Aerobic Plate Count (AC), Coliform and E. coli (EC), and Yeast and Molds (Y&M). The APC and EC Plates are AOAC-RI and PMO-NCIMS approved. Each version of these tests contains non-selective or selective medium and follows conventional microbiologic procedures for time and temperature of incubation.

Selected Peel Plate microbial tests are available for sample volumes of either 1 mL or 5 mL (High Volume).High Volume (HV) microbial tests use a 5 mL sample volume. A 5 mL aliquot of a 1:5 dilution (or 5 mL on each of 2 plates of a 1:10 dilution) is added to the HV plate and is then incubated. 100 mm diameter is convenient for sample filters and 100 mL water samples or larger, including wine and beverages.

The tests are prepared media in a shallow dish with an adhesive top. Plates are ready-to-use and no spreading device is needed. Just add the sample to the middle and it wicks through the media and solidifies. Invert the test, stack multiple tests together (if appropriate) and incubate. The sample wicks rapidly to cover entire surface. An air gap between the plate and cover allows colony picking and determination of microbial morphology.

Peel Plate tests are used in dairy products, ground meats, other foods, contact surfaces and water. Colony development is easily quantified by color.

Peel Plate AC Bacterial Test

AC tests use traditional standard plate count formulation with red producing TTC enzyme substrate. Aerobic bacteria produce red spots that are quantified over the 24-48 hour incubation at 32 ± 1°C for 48± 3 hours for dairy products, or at 35 ± 1°C for foods and environmental sponge samples. Each spot represents 1 CFU. The sum of spots is reported as the CFU/mL or CFU/gram per dilution tested.


Peel Plate CC Bacterial Test

CC (Coliform) use conventional coliform media with color producing enzyme substrates and a 24 hour incubation at 32° C and produces red colonies.


Peel Plate EB Bacterial Test

EB (Enterobacteriaceae) use a conventional formulation with 48 hour incubation at 37° C and produces colored colonies.


Peel Plate EC Bacterial Test

EC (E. coli and Coliform) tests use traditional EC media with color producing enzyme substrates and a 24 hour incubation. Coliforms produce easy to interpret red colonies that do not need additional confirmatory steps or difficult to interpret gas production. Most E. coli produce blue/purple colonies. The quantitative method is applicable for determination of total coliform, sum of coliform and E. coli, in dairy products at 32± 1°C incubation. The method will detect E. coli from coliform in ground beef, food, carcass rinses, environmental surface sponge and water samples at 35 ± 1°C incubation. The sum of colonies equals total coliform. Read spots are coliform and bluish-black spots are generic E. coli.


Peel Plate YM Bacterial Test

Y&M test use traditional formulation with colonies that are blue, green or gray and quantified at room temperature or at 25 ± 2°C for 3 to 5 days. Each spot represents 1 CFU. The sum of spots is reported as the CFU/mL or CFU/gram per dilution tested.
