More information about this application

CSSP is a federal food safety program jointly administered by the Canadian Food Inspection Agency (CFIA), Environment and Climate Change Canada (EC) and Fisheries and Oceans Canada (DFO). The goal of the program is to protect Canadians from the health risks associated with the consumption of contaminated bivalve molluscan shellfish.

This application helps to achieve the program goal by providing Canadians with up-to-date information on shellfish harvesting areas that are closed due to contamination. It also serves as an extension of the DFO Fisheries Notices System.

Some of the features of the application include bookmarking an area or region, zooming in and out of an area, and subscribing to notification emails on openings, closures, and public consultations.
