Request Your Free Environmental Monitoring Kit Today!

Using the Charm Peel Plate Microbial tests and PUR-Blue Swabs, you can easily swab and plate environmental monitoring samples.

Peel Plate tests are simple to use and easy to interpret. Sample swabs containing neutralizing buffer reduce bacteria interference to recover more bacteria on surfaces and equipment.

With Your Free Trial You’ll Receive:

  • Five PUR-Blue Swab
  • Five 1 mL Peel Plate Microbial Tests

Tests Available:

Peel Plate AC

Peel Plate AC nutrient rich non-selective media encourages the growth of all aerobic, oxygen consuming bacteria. Aerobic counts are used as tools in identifying sanitation issues, potential shelf life issues, and are considered elevated listeria risk indicator in food production environmental monitoring. Peel Plate AC are AOAC-RI validated and PMO approved for a variety of dairy, food and environmental samples. Aerobes appear as red spots with a defined center within 48 hours at 32 or 35ºC; size may vary.

Peel Plate CC

Total Coliform Peel Plate CC selective media encourages the growth of coliform bacteria. The presence of coliform is an indicator of unsanitary conditions in raw products. Coliform are killed by effective heat steps in food processing.  Coliform appear as red colonies within 24 hours at 32 or 35°C. Coliforms are closely regulated in dairy and some foods in the US. Peel Plate Coliform tests are listed in the PMO.

Peel Plate EB

The Enterobacteriaceae bacteria are a family of gram negative bacteria encompassing coliform, E. coli, Shigella, Salmonella, and Yersinia. These bacteria indicate unsanitary conditions in raw products and are killed by heat steps in food processing. EB testing is used as a post-production verification of process and pathogen risk used, for example, to test dry milk powder and infant formula. EB is regulated globally, similar to coliform/E.coli regulation in the US. Incubation 24 to 48 hours at 37°C produce multiple colored round growth spots that are all recorded as EB.

Peel Plate EC

Generic E.coli and indicator of fecal contamination are considered a fecal risk indicator, are a subset of coliform and are differentiated with the Peel Plate EC formulation. Peel Plate EC are AOAC-RI validated for a number of dairy products, meat rinses, water testing, and environmental sampling. Coliform appear as round red colonies and E. coli as round blue colonies within 24 hours at 35°C and the sum of red and blue are total coliform.

Peel Plate HET

Heterotrophs are aerobic bacteria that are more associated with water and nutrient depleted matrices. Peel Plate HET nutrient depleted media encourages the growth of heterotrophic organisms in water. Incubation at 25°C produce red growth spots within 5 to 7 days. Heterotrophs are used as indicators to assess biofilm build up, and nutrient leaching in water distribution systems of food plants and water municipalities.

Peel Plate YM

Peel plate selective media with antibiotic prevents the growth of bacteria, and encourages the growth of fungi. Fungi organisms are primarily a food spoilage risk but can also produce toxins. Peel Plate YM are AOAC-RI validated for a variety of dairy products, fresh fruits and vegetables, juices, RTE foods, and environmental surfaces. Incubation 3 to 5 days at 25ºC produce green/blue growth spots.
