| Additional information: | Shellfish homogenates are received on ice, extracted, and a Neogen rapid test determines whether the mussel sample is positive or negative. Mussel samples that are positive on NeoGen are then tested using a mouse bioassay to determine concentration of PSP toxins. All other species are only tested with mouse bioassay. | |||||||||||||||||||||
