Tom and I returned home from Kauai yesterday. We had a wonderful vacation without children this time. They had plenty of fun at home with grandma though! This post is more than a recipe. In fact, after I learned more about mercury levels in Hawaiian fish, I debated posting this at all. But we all make mistakes, and I want to share what I have learned.
After eating this meal two days in a row, I had the thought to check one of the fish lists for safety of consuming opah while pregnant. Sure enough, it is on the avoid list if pregnant and "consume no more than one serving a month" for adults. Luckily I never consume fish with elevated levels of mercury so I don't feel this will pose a significant problem. Mercury in fish damages brain tissue, especially in developing fetuses, infants, and young children. It also damages heart tissue in adults and male reproductive organs and sperm. Two-thirds of mercury in our environment comes from coal-burning power plants, and a significant amount comes from medical and municipal waste. Microorganisms convert elemental mercury to methylmercury, a toxic form of mercury that our bodies cannot get rid of. It first accumulates in microorganisms at the bottom of the food chain and then moves up the food chain ultimately reaching the highest levels in predatory fish (tuna, shark, king mackerel, swordfish, opah, ono). Interestingly, through my research I also learned that opah, like tuna and other deep water fish, are caught by longline fish practices, a type of fishing that places thousands of hooks on a long line. This practice kills many sea birds and other marine creatures, such as sharks, dolphins, and sea turtles in the process.
Mercury in our food supply is a significant issue. When new scientific findings were released that canned tuna contained very high levels of mercury, the EPA downplayed the findings (the tuna industry is big, think lobbying, and the effect on the economy with a large drop of tuna consumption). You'll still see canned tuna on some of the "safe to eat lists" though in reality, it is not safe at all for pregnant women, children, or women of child-bearing age to consume. In fact, children can receive doses of mercury four times the acceptable level by eating six ounces of tuna a week! More info on mercury in fish can be found on websites such as EWG.org. Mercury has also been found in high-fructose corn syrup and therefore also in commercial foods that contain this ingredient, such as snack bars, barbecue sauce, jelly, yogurt, and chocolate syrup. What are we doing to our environment that we can't rely anymore on local food supplies? We are the cause of many of the problems ailing us today, and we are also the solution. Hopefully this post brings to light some of the issues that can be changed when we focus on human health and the health of our planet instead of the almighty dollar.
For a list of safe fish to consume check out this downloadable PDF from GreenAmerica.org or the Smart Seafood Guide 2010 by the Food and Water Watch. This recipe for fish tacos can be made with many of the fish on the safe list. When we make fish tacos at home, we use wild Alaskan salmon. Pictured here is also a fresh salsa that Tom made a few nights in a row (to go with our beans and rice). It is made from tomatoes, avocado, papaya, onions, lime juice, garlic, cilantro, and Hawaiian hot chili peppers. Or try serving them with this Papaya Salsa Recipe. We also like to serve fish tacos with thinly sliced napa cabbage and homemade guacamole.
1 1/2 to 2 pounds "safe" fish, skinned and cut into chunks
2 large limes, juiced
2 to 3 cloves garlic, peeled
3 Hawaiian hot chili peppers or 1 to 2 jalapeños
1 to 2 teaspoons cumin
1 to 2 teaspoons Herbamare
coconut oil for sautéing
sprouted corn tortillas
sliced napa cabbage
It is much easier to have the fish skinned when you are purchasing it, otherwise you will need a very sharp knife and some skill. Place the chunks of fish (I usually cut it into 1 to 2-inch cubes) into a shallow baking dish, such as an 8 x 8-inch pan. Place the remaining ingredients (lime juice through Herbamare) into a blender and blend for 30 to 60 seconds. Pour marinade over fish. Marinate for about an hour.
To cook the fish, heat a large heavy-bottomed, stainless steel skillet over medium-high heat. Let the pan heat up for a few minutes, then add about 2 tablespoons of coconut oil. Add the fish, start with 1/3 to 1/2 the fish if your skillet is smaller (say 10-inches). If you add too much fish at once to a skillet, it is not able to sear and retain its liquid, therefore drying out quickly. You'll notice a bit of water at the bottom of the pan if you add too much at once. Sauté for 3 to 4 minutes, depending on the size of the pieces. Remove from the skillet, add a little more oil, and then cook the remaining fish.
Serve with corn tortillas, salsa, guacamole, sprouts, and thinly sliced napa cabbage.
