MOCON’s GreenLight® system provides aerobic bacterial load measurements at any point in the value chain, at a lower cost and 10 times faster than traditional plating. This system enables producers to gain control over processes, reduce preparation costs, save time, track trends and gain flexibility without a laboratory or extensive training to operate.
The GreenLight system uses unique oxygen-depletion technology in the form of an integrated vial sensor to eliminate the need for sample dilution, plate counting and waiting for incubation cycles. The intuitive software records all results in a database for easy reporting, analysis and historical comparison.
The GreenLight method has received AOAC and MicroVal approval for raw meats and poultry.
MOCON, the world leader for over 45 years in permeation and package integrity analysis, is leading the way with automated instruments providing fast, accurate, low cost, screening to aid early detection of food-borne pathogens.
Time To Result:
- (Using internal incubation); one concurrent test at a time until time-to-result (see above)
- Other operating modes (external incubation); Multi-Point mode 72 tests until the last test is complete; Pass/Fail mode 216 tests on a fixed time interval
- (Using internal incubation), up to 48 concurrent tests. Load new tests at any time as long as a carousel position is available
- Other operating modes (external incubation); Multi-Point mode 3x48=144 tests;
Pass/Fail mode 9x48=432 tests
How the automated GreenLight System detects bacterial load (2:13)
An increasing appreciation for the importance of food and microbiological safety has resulted in a demand for a more rapid, high-throughput method for total viable count (TVC) quantification to deal with the increasing numbers of samples that require testing. The industry standard for TVC determination (ISO.4833.2003), also known as aerobic plate count, is widely used but presents users with some very significant drawbacks. The method is both materials and labour intensive, requiring the preparation and analysis of multiple agar plates per sample. More i ...
In food process facilities, it is common practice for equipment and surfaces to be tested for cleanliness by swabbing. Usually, the recovered microbial load from a swab is submitted for evaluation of the Aerobic Plate Count (APC), also known as Total Viable Count (TVC). The reference methods for enumerating APC (TVC) include the BAM method and ISO 4833:2003. Both of these methods require preparation, dilution and plating on agar, resulting in a high degree of manual labor and long periods of incubation up to 72 hours.
The GreenLight® system was designed for applications across the food industry with further uses in environmental measurements. The core technology is a novel oxygen-depletion sensor that can detect very small changes in oxygen content making the system ideal for use in enumerating aerobic microbes. Here we describe a small comparative study conducted by Luxcel Biosciences, assessing correlation between the GreenLight system and standard plate count (SPC) for local raw milk. GreenLight demonstrated strong correlation to SPC with improvements in time-to-result, ...
