| Kit used: Yes | Type of kit used: Abraxis Okadaic Acid (PP2A), Microtiter Plate | |||||||||||
| Additional information: | Toxin was collected by use of solid-phase adsorption toxin tracking (SPATT) samplers filled with Diaion™ HP20 resin. The PP2A kit used to quantify concentrations of okadaic acid has maximum and minimum detectable concentrations of 352 and 63 μg/kg, respectively. | |||||||||||

| Management decision: | It should be noted that detection of DSP in shellfish resulted in the closure of the entirety of Old Fort Pond (~80 acres) to the harvesting of shellfish and carnivorous gastropods on 11-July-2019. This closure was rescinded on 18-July-2019. | |||||||||||
