I found it a little surprising to read a couple of weeks ago that, even in Australia, parents should not feed too much large fish to their very young children, due to the risk they will get too much mercury.
Do big fish everywhere in the world have too much mercury in them? If so, how long has this been the case? Furthermore, even some not so huge sized fish can be a problem:
Orange roughy is an interesting, ugly fish, as being a member of the slimehead family would tend to indicate. (Oh the cruel taunting that must go on in fish schools. Ha ha.) But, as it lives in deep cold water, which I generally assume is far from mercury producing shores, I did not expect it to have a mercury problem. Still, if you live for a hundred years before someone eats you, I guess there is a lot of time to accumulate bad things in your flesh.The NSW Food Authority's chief scientist, Dr Lisa Szabo, said there were only six types of fish parents needed to worry about - shark, broadbill, swordfish, marlin, orange roughy and catfish.
"In part it's because they're bigger," Dr Szabo told reporters.
"But they're also longer lived and they're predatory fish, which means that they eat a lot of small fish so that's why they tend to accumulate the mercury."
Anyway, this is all by way of long introduction to a minor anecdote about a problem with Melbourne, or perhaps it is with Victorians generally.
I have said for decades that, despite the fact that I really don't like its weather (particularly its winters which are grey, wet and seem to take forever to leave, and yet never have the hope of the prettiness of snow,) Melbourne is the best place in Australia to eat. My theory is that this was historically prompted not only by foreign immigrants, but also by the fact that the weather means there is nothing else to do for 8 months of the year other than to stay indoors.
However, there is one area where Melbourne is still disastrously backward in the matter of food: the suburban fish and chip shop.
While staying at Williamstown recently, my wife noticed a pretty new looking fish and chip shop that had lots of customers, and had a great position across the road from the water. She suggested we eat from there. Before we went into the shop, I told her that maybe it would be OK, but I knew from past experience that Melbournians had a peculiar feature in that they assumed fish and chip shops need only sell flake (shark).
In contrast, the Brisbane fish and chip shops of my childhood sold everything but flake - whiting, flathead, snapper, sea perch (a.k.a. orange roughy, incidentally.) Flake only started appearing in Brisbane as an option in (I would guess) the 1980's.
Maybe Melbourne has changed, I said to my wife. Surely it has caught up with the times and sells something other than the strangely textured gummy shark, which I think most Brisbane people still quite rightly disdain. (I think from childhood holidays in Sydney that it wasn't very popular there either.)
But no, the very fancy looking, popular fish and chip shop in question sold only flake, and I don't think it was because they had run out of other fish either.
We walked up the road to another fish and chip takeaway, a much less fancy looking one, and its extensive fish menu was flake and something sold as whiting (although the latter turned out to be something suspiciously large and not exactly of whiting shape.)
Although my sample of shops was admittedly small, I still feel confident in saying that Melbourne for some mysterious reason is still the worst city in Australia to eat take away fish and chips.
(Why did they ever accept small shark as the default choice for takeaway fish in the first place? Anyone know the history of that?)
