Hi Alysia! I love sushi as well, so scrolling through the Monterey Bay Aquarium Seafood Watch website put things into perspective for me regarding how our ignorance continues to fuel food web disruptions. I never knew that it was better to purchase seafood harvested from certain areas over others. I assumed that “local was always better,” but I guess that there are certain exceptions for seafood harvesting. Additionally, not once have I ever thought about the potential contaminants in sushi. In general, whenever I think about seafood and its relationship with the climate crisis, I typically think about how overfishing leads to drastic alterations in marine food webs. As such, I really appreciate you for pointing out that seafood contamination is a prominent issue that many people turn a blind eye to. You inspired me to do more research on this issue, so I found out from the EDF Seafood Selector that other contaminants in seafood (besides mercury) include pesticides and lead. Ironically, these contaminants enter marine creatures’ bodies as a result of our own actions. These contaminants eventually reach water as a result of “[i]ndustrial and municipal discharges, agricultural practices, and storm water runoff.” In other words, we are inadvertently poisoning ourselves by continuing our unsustainable industrial and agricultural practices. We cannot eliminate our trash by merely dumping it into the ocean because in doing so, we are directly polluting our seafood sources. Even more so, we are overfishing certain species in areas that are in desperate need of stricter fishing policies. If a certain population goes extinct, this will create a large imbalance in marine food chains that help to regulate the different features of a habitat (e.g., temperature, gas levels, etc.). The sad part is that most consumers don’t know or care to inquire where their restaurant seafood came from or where the seafood at their local grocery store was originally harvested. If we don’t know about the more sustainable ways to shop for/consume seafood in the first place, how can we ever be expected to modify our shopping habits?
Regarding your concern on not knowing where restaurant/grocery store seafood is coming from, I think certain grocery stores/companies are beginning to include that particular information on their packaging! If you visit a deli display, there may be certain labels on the seafood items that indicate that they come from, for example, New England (or a more specific state). However, sometimes, just seeing the term “New England” is vague. Where in New England is it from? I do not think it would do any harm to ask if the butcher is aware of where these foods are getting sourced from. The same goes for asking a restaurant manager/owner these same questions. Certain freshwater lakes or coastal edges bordering different states may be more affected than others. It’s important that we pinpoint the body of water that the seafood came from as well as which states that body of water shares borders with. With this knowledge, we can avoid purchasing seafood from areas that are facing an overfishing crisis. Even if certain packaging styles may not tell you the precise location of where the product came from, it’s also a good habit to keep an eye out for other labels indicating sustainability measures. As I’ve mentioned in other posts, the frozen Atlantic salmon fillets from Whole Foods are packaged with a sticker that indicates that they were “responsibly farmed.” On the back side of the packaging, there are several bullet points detailing what criteria must be fulfilled in order for that label to be placed on the package.
I acknowledge that I can be “lazy” at times, and I would love if most of the research could be laid out for me regarding seafood sourcing, but I don’t think it would be very difficult for us to do a quick Google search to see if we can find more information on where certain companies harvest their seafood. I am definitely going to send my family the link to the Monterey Bay Aquarium Seafood Watch website so that they can also make informed decisions before purchasing seafood at the grocery store. If you ever happen to do more research on the contaminants of seafood, I would love to hear more about your findings!
