SEAFOOD MYTHS
Many myths and misconceptions have sprung up
concerning seafood. As is the way with myths, they are
handed from generation to generation, reinforced with each
telling, until they become an almost inherent part of the
culture in which they grew. Nor are these myths fare for
the unlearned; educated people are likely to believe them
as well. Here are a few of the myths and misconceptions
concerning seafood that have come down through the years:
* Oysters and other shellfish should be eaten only in
months with an "r" in them. So far as the United States is
concerned, this is not true. Under commercial raising and
harvesting conditions, oysters and other shellfish are safe
and good to eat any month of the year. Certain European
oysters, which brood their young in months without an "r"
are less palatable at that time of year, but this rule
doesn't apply to U. S. oysters, which don't brood their
young. As a contradiction to the myth about "r" months,
shellfish containing a paralytic shellfish poison are
occasionally found along the Pacific Coast in "r" months.
When this occurs, people are warned against gathering and
eating these particular shellfish. The California
Department of Health places a quarantine on the harvesting
of mussels between May 1 and October 31; and along the
Oregon Coast, people are warned by the news media against
gathering and eating the mussels that cling to rocks that
rim the beaches. The cardinal rule is that any
commercially available shellfish is non-toxic and safe to
eat.
* Oysters are an aphrodisiac. The idea of eating
oysters for their aphrodisiac qualities, which has been
around for a long time, is basically untrue. Oysters do
contain considerable amounts of nature's building block,
cholesterol, as well as being extremely rich in protein --
although it is doubtful that this was common knowledge when
the aphrodisiac myth was perpetrated.
* Shellfish that die before being cooked should not
then be cooked and eaten. People have been warned not to
eat clams, mussels, crabs, lobsters and other shellfish
unless they are alive when cooked. From the standpoint of
flavor, this is a good suggestion, but shellfish don't
become toxic when they die. When shellfish die, their
digestive glands break down, releasing digestive enzymes
that begin digesting the flesh of the animal. Cooking the
shellfish alive prevents this process from beginning. The
reason you should only clean and cook live or frozen
shellfish is that those that die before being cooked or
frozen will have a decomposed flavor and odor.
* Seafood it a brainfood. The myth of fish as a brain
food goes back to a 19th Century Harvard University
scientist who discovered that phosphorus is abundant in the
human brain, and from this fact, wrongly concluded that a
diet of fish should increase the human IQ.
* Eating seafood with fresh milk will make you sick.
This is totally untrue, both from observation and the
application of logic; the combination of two wholesome
foods cannot possibly make one sick.
* Mahi-Mahi is actually porpoise meat. This myth
probably originated because the Mahi-Mahi is also called
dolphin fish or dolphin. Mahi-Mahi is really a fish,
caught in tropical waters and marketed throughout the
world. The dolphin, as a mammal, is protected by the 1972
Marine Mammal Protection Act, and is not harvested or used
for food in the United States.
* Frozen seafood is inferior to fresh seafood. This
is more a simple fallacy than a myth and probably
originated around the time when the marketing of seafood
went through the transitional stage from primarily
refrigeration and icing methods, to freezing methods. The
truth is that fresh seafood is processed quickly after
being harvested, with surpluses beyond the immediate
marketing demands being frozen by the "glaze" method, which
literally coats the product with a layer of ice. This is
an improvement over the old dry-freezing method, which
itself was a viable way of handling a highly perishable
product. Fresh-frozen seafood is of exactly the same
quality and flavor as when it was frozen.
