Lobster Contaminants
Title
Screening the Levels of Lead, Cadmium, Arsenic, Chromium, Zinc, Mercury, and Thallium in the Traditional Food-Lobster of Eel River Bar First Nation
Description
The purpose of this project was to examine the concentrations of heavy metal contaminants: cadmium, lead, arsenic, and mercury as well as chromium, thallium and zinc within the lobster traditionally consumed by the Mi’gmaq of Eel River Bar, New Brunswick.
A total of 44 lobsters we tested, where 22 were cooked and 22 were raw. Due to high laboratory analysis costs, a decision was made to test both lobster meat and tomalley together for each lobster.
The mean concentrations for all 44 lobsters were found to be lower than the maximum allowed levels according to International standards for arsenic, cadmium, lead, and mercury. However, when observing the levels of heavy metals in individual lobsters, five (5) lobster had levels of cadmium that were in excess of its respecting International standard of 0.5 mg/kg set by the Commission of the European Communities. There were no International standards identified for chromium, thallium and zinc in lobster. There was no observed correlation on the concentrations of heavy metals between raw and cooked lobster.

Fish Parasites
/in News /by clabilloisThe Gespe’gewaq Mi’gmaq Resource Council (GMRC) has received reports from community members about parasites being found on smelts. These parasites are known as copepods, and are commonly found in smelts. We want to inform our community members they have no adverse effects on humans if you thoroughly cook your fish.

/in News /by clabilloisThe shoreline in Listuguj is looking cleaner today after staff from the Gespe’gewaq Mi’gmaq Resource Council (GMRC) spent Thursday afternoon picking up trash along the river. A total of 13 bags of litter were removed, along with large metal objects and plastics. GMRC organizes shoreline cleanups in our membership communities, making a big impact in keeping litter from entering our waterways. Staff also pick up litter when out conducting fieldwork throughout the year. We encourage you to help keep our territory clean and leave a lighter footprint on Mother Earth.
