Peel Plate

Staphylococcus Aureus

Staphylococcus aureus, commonly found on the skin, hair, noses, and throats of both people and animals, can also be present in eggs, meat, poultry, milk, and dairy products within food processing environments. The bacteria can spread through hand contact with surfaces or hand-prepared food items, especially in the absence of proper hygiene. S. aureus rapidly multiplies at room temperature and can cause illness upon ingestion.

Benefits of Charm Microbial Peel Plate Tests

• Ready-to-use, self-wicking design with no additional spreading device required.
• Colonies easily transferred or picked for further confirmation, isolation, or classification.
• Improved air circulation with spaced, interlocked plates.
• Buffered media formulation ensures robust performance with acidic foods and neutralizing buffers.
• pH adjustments not needed for most samples.
• 12-month refrigerated shelf-life in a resealable foil zip bag.
• Verified for dairy, foods, rinse water, and surface samples at 35-37 °C.

Staphylococcus Aureus Testing Solution

The Peel Plate SA Microbial Test is a pre-prepared culture medium designed for the enzymatic detection and enumeration of Staph aureus bacteria in finished products and environmental samples.

Peel Plate SA Microbial Test kits are suitable for testing liquid foods, solid foods, and environmental sponge samples. The distinctive purple-colored colonies of coagulase-positive S. aureus are easily discernible against the light background of the Peel Plate, differentiating them from the green and green-blue colonies of most coagulase-negative Staphylococci and related Enterococci species.

S. aureus bacteria become visible within 24 hours, with an additional 24 hours for purple colony presumptive positive determination (48 hours total) at 35 to 37°C. Tests with no growth at 24 hours are considered negative for S. aureus. Presumptive positive colonies are confirmed as Staph aureus following FDA-BAM procedures for verifying the enzymes catalase and coagulase positive.

Charm Peel Plates Microbial Tests are user-friendly and eliminate the need for a spreader device. Samples are securely contained within the Peel Plates, minimizing the risk of contamination from leakage. Colonies can be effortlessly transferred or picked for confirmation testing, additional isolation, or classification. Charm Peel Plates Microbial Tests provide easily interpreted results for Staphylococcus aureus within 24-48 hours, with no overlays required.
