Food Production Daily has reported on a novel system for TVC which has received approval from MicroVAL for raw meats and poultry. The system is by a company called Luxcel Biosciences and is called GreenLight.
GreenLight™ Model 960, is a high-throughput test that provides total aerobic viable counts (TVCs, APCs) for food samples by measuring bacterial oxygen consumption and equating oxygen consumption to microbial load. As bacteria in the test sample grow and respire they deplete O2 which is detected as an increase in the GreenLight™ probe signal above the baseline level. The time required to reach this increase in signal is used to calculate the CFU/g of the original food sample, based on a pre-determined calibration.
