Product Information

Based on international guidelines, Food Standards Australia New Zealand also provides recommended safe limits for dietary intake. In other words, how much mercury you can safely have from food sources (not just fish). We found none of the canned tuna brands exceeded the safe consumption levels for mercury of 0.5 milligrams of mercury a kilogram. All three tins had slightly different levels of mercury but even the "worst" one wasn't that bad. Fish is a very good source of protein – it's a complete animal protein, which means it's got all the amino acids and is very bio-available," she says. Given the very low sample numbers, our data is just a snapshot of mercury concentrations. More research is clearly needed.

However, whether mercury is harmful or not also depends on the amount of fish you eat and how often. After all, it is the dose that makes the poison. For the batter, combine the ingredients in a bowl and gently whisk until just smooth and lump-free. Any discussion of tinned fish will not only feature debate about the best choices nutritionally but also the way the fish is caught, and the sustainability practices employed by the major producers around the world. Even though there are many varieties of tinned fish on supermarket shelves, there are many similarities across the brands. The good thing about this is that varieties with clear nutritional benefits really stand out, as do the brands that employ sustainable fishing practices Salmon Food Standards Australia New Zealand recommends that, for orange roughy (also known as deep sea perch) or catfish, people should limit themselves to one 150 gram serving a week with no other fish that week. For shark (flake) or swordfish/broadbill and marlin, the limit is one serving a fortnight. At the time of the ranking, Greenpeace observed that Sirena traded primarily in overfished yellowfin tuna. Like many of the bottom-ranked tuna brands they also continue to source most of their range from purse seine vessels using FADs. Sirena also make misleading claims about sourcing fish from local producers.The best approach to sustainability, says Hanich, is the pole-and-line fishing method, in which fish are caught with a single pole, line and hook. Compared to the more prevalent purse seine method (see below), pole-and-line is considered the best way to reduce overfishing and bycatch.

pole-and-line, but uses yellowfin and tonggol tuna, and has poor labelling that doesn't specify the species. Woolworths Tuna in spring water tends to have less flavour, but Austin says it can be a good option for cooking. On the bottom of the list is the Sole Mare brand. Their product consists entirely of Yellowfin tuna. Sole Mare does not provide any information on fishing method used or catch area. Clearly there is lots of room for improvement here. This method also requires more fishermen than the big industrial operations, creating more local jobs in the Western Pacific (where almost all Australian tuna comes from). FAD-free purse seine tuna The dose for pregnant women is approximately half this value — 1.6 micrograms per kilogram of body weight per week).A purse seine is a large floating wall of netting that encircles a school of fish and is 'pursed' on the bottom, preventing fish from escaping by swimming downward. The catch is harvested by hauling the net aboard or bringing it alongside the vessel. Described as "the benchmark of sustainable fishing practice", it has 100% pole-and-line-caught tuna. Safcol Combine the onion, cream, mustard, salt, pepper and cornflour in the bottom of a large mixing bowl and mix thoroughly to distribute ingredients and remove any lumps of cornflour. The label 'dolphin friendly' is completely irrelevant in the Western Pacific," says Hanich. "It's the equivalent of saying it's koala friendly, because the chances of catching a dolphin are about the same as catching a koala in the nets."
