It’s not unusual for people to have shellfish allergies, but even non-allergic people can get sick from eating shellfish, thanks to contamination that occurs when the filter-feeding sea creatures take in toxins in warm ocean waters. Now, research is showing that the algae and bacteria that cause these toxins are becoming more prevalent as sea […]

Unraveling acronyms: What are ASP, DSP and PSP?

Shellfish poisoning can occur when shellfish contaminated with any of a number of marine toxins are consumed. The individual toxins can lead to a range of conditions and symptoms.

Robotic sensor used to search for harmful algae, pathogens

There are some pretty cool things beneath the waters of Puget Sound – fish, shellfish, robots.

Yes, robots, and they’re doing an important job. This summer, the National Oceanic and Atmospheric Administration’s (NOAA) Northwest Fisheries Science Center (NWFSC) deployed a robotic sensor called the environmental sample processor (ESP) to detect the presence of algal blooms […]

Marine toxins halt shellfish harvest at Scottish site

High levels of naturally-occurring toxins at a shellfish harvesting site in Scotland have led to the site’s closure.

About 70 people have reported symptoms that are consistent with diarrhetic shellfish poisoning (DSP), which is caused by the consumption of toxins in the okadaic group. The toxins are produced by the marine dinoflagellates such as Dinophysis, […]
