The SRT PSP test is a yes/no rapid test for PSP toxins that can be used with bivalves such as mussels, clams and oysters as well as lobster tomalley.  This test involves converting the shellfish into a liquid form (known as the extract) which can then be applied to the test.

The SRT PSP test is simple and easy to use and can be performed easily in a seafood processing plant, shipboard or dockside. It is fast and can give quick reliable results of seafood ready to be processed or a catch fresh off the ship.

The testing method is completed in three basic steps:

 

Step 1: Prepare sample

For Shellfish: Remove tissue from the shell and grind till smooth

For Lobster Tomalley: Remove tomalley from the lobster and blend till smooth

For Algae: Filter seawater and collect algal cells

 

Step 2: Prepare Extract

For Shellfish: Extraction process converts ground shellfish into a liquid form using one of two methods:

  1. Positive results obtained in a regulated environment will need further analytical testing by High Performance Liquid Chromatography (HPLC) or Mouse Bioassay (MBA). This will require using the AOAC Extraction.
  2. If further testing is not required, then use Rapid Extraction.

 

For Lobster Tomalley:

Extraction process converts blended tomalley into a liquid form. This will require AOAC Extraction method.

 

For Algae:

Extraction process converts the collected algal cells to liquid form using the Phyto Extraction.

 

Step 3: Proceed to Scotia PSP Test

To test, dilute shellfish, tomalley or algal extract in the buffer provided with kit and apply sample to the test cassette.

For further details on how to perform the test see PSP AOAC, PSP Rapid or PSP Phyto testing instructions.
