吃牛肉和三文鱼哪个更安全？
国内的人都说美国牛肉不能吃，那养殖三文鱼呢？
看这个，似乎是和部位/吃法有关.

牛肉是红肉，不如三文鱼健康，野生的三文鱼的omega 3含量很高

哈哈，想起来我两年前写的一篇小短文。最后一句话是：

从文章上看，好像二者都是好食材
三文鱼：优点： omega-3 fatty acids 可以翻作优质脂肪酸，
多食用，可以代替易引起心血管病的高密度脂肪酸。
忧虑：养殖的含PCB。（一种毒素？）测量结果表明，是限制含量的千分
之一左右。
不足为惧。
特别解决办法：不吃鱼皮。
牛肉：优点不多讲。
缺点：可能引起疯牛病
其实产生几率很低。
特别解决办法，只吃steak。因为疯牛病来自脑里的妧病毒。
salmon： The FDA has set the safe upper limit for PCBs at 2000 parts per
billion (ppb). Farmed salmon averages 27 ppb, well below that limit. T
If you are concerned about PCBs, remove the skin and dark flesh from your
salmon, and cook it so that the fat drips off -- thus reducing PCBs by 20%-
30%.
beef： If you are concerned about PCBs, remove the skin and dark flesh from
your salmon, and cook it so that the fat drips off -- thus reducing PCBs by
20%-30%.

Salmon and Beef: What's Safe to Eat?
Amid the flurry of headlines about the food industry, it's a challenge to
figure out what is safe to eat: Is mad cow disease a real threat? Does
farmed salmon cause cancer?
Many consumers are racing to buy organic foods to avoid potential toxins in
their grocery carts. But are we overreacting, or is there really cause to
shun our food supply?
When it comes to two of the most recent foods called into question -- beef
and salmon -- it boils down to a matter of risk vs. benefit. To help you
decide whether these foods are for you, let's take a serious look at the
science behind the headlines.
The Salmon Scare
A report in the January issue of the journal Science touched off alarm that
farmed salmon contained levels of polychlorinated biphenyls (PCBs, a kind of
dioxin) that could be harmful. The concern over PCBs stems from their role
as a likely carcinogen in humans, based on studies in animals.
In an ideal world, there would be no PCBs. But unfortunately, they exist in
the air that we breathe and in many foods we eat, including chicken, butter,
and both wild and farmed salmon. PCBs get into wild salmon from the other
fish they eat and into farmed salmon from their feed (which contains many of
these same fish).
The FDA has set the safe upper limit for PCBs at 2000 parts per billion (ppb
). Farmed salmon averages 27 ppb, well below that limit. The controversy has
come about because another branch of the government, the Environmental
Protection Agency (EPA), has set a much lower safe limit for PCBs in food --
4.5 times lower, in fact.
Keep in mind that these two agencies are charged with different functions.
The EPA sets limits meant for recreationally caught fish, while the FDA's
limits are intended for fish sold commercially. The FDA's higher limit is
also supported by the World Health Organization and the European Union.
Although the amount of PCBs found in most fish is only 1/80th of the FDA
safe level, ''The farmed salmon industry is working to further reduce PCBs
in fish feed while maintaining the healthful omega-3 fatty acid content,''
says Alex Trent, executive director for the industry group Salmon of the
Americas.

The Salmon Scare continued...
The American Heart Association maintains that eating two servings a week of
oily fish (like salmon) can help healthy adults ward off sudden cardiac
death, thanks to the protective effects of omega-3 fatty acids. The best
source of these omega-3 fatty acids is farmed salmon, though they're also
found in flaxseed, walnuts, soybeans, and oils made from these products.
Many longstanding studies have documented the health benefits of a diet rich
in omega-3 fatty acids and their role in guarding against heart disease.
More recent studies have indicated that omega-3s may even help keep your
mind agile and protect against Alzheimer's disease. And salmon, like other
fish, is an excellent, low-fat source of protein that many people enjoy
eating.
What can we conclude from this? It's a decision each of us needs to evaluate
personally, of course. But for most healthy adults, the health benefits of
salmon far outweigh the much smaller and less-clear risk that the PCBs found
in it could cause cancer. (Children and pregnant or nursing women may be at
increased risk of exposure to contaminants and should check with their
doctors for advice on eating all kinds of fish.)
Let's put the issue into perspective. The leading cause of death in the U.S.
-- causing 950,000 deaths a year -- is cardiovascular disease. Eating two
meals per week of fatty fish, such as salmon, can reduce the risk of fatal
heart disease by 40%. The dangers of eating salmon, meanwhile, are unclear,
largely theoretical, and based on studies in animals. The risks would appear
to be much smaller than that of developing heart disease.
If you are concerned about PCBs, remove the skin and dark flesh from your
salmon, and cook it so that the fat drips off -- thus reducing PCBs by 20%-
30%.
How Safe Is Our Beef Supply?
Because we eat so much beef in the U.S., it's especially important that we
be confident of its safety. The CDC says that the risk of a consumer in this
country contracting the human form of mad cow disease is "extremely small."
In testimony presented to the Senate, CDC Director Julie Gerberding said U.
S. authorities had taken adequate steps to reduce the risk.

How Safe Is Our Beef Supply? continued...
Studies have revealed that the agent responsible for mad cow infections is
not found in beef muscle or in milk. The disease is spread by proteins
called prions, which are found in the central nervous system tissue -- such
as the brain and spinal cord -- of cattle. Prions cannot be destroyed by
cooking.
Only one cow infected with the disease has been found in the U.S. According
to the National Cattlemen's Beef Association, the central nervous system
material from that cow -- found in Washington State -- did not enter our
food supply. And the entire herd associated with that cow has been
slaughtered and disposed of.
Since that case, the government has banned so-called "downer" cattle --
those that are unable to walk -- from being used as food for humans. And it
now prevents processors from using cattle brains and small intestines from
older cattle in human food. Still more regulations may be established to
ensure that our supply of beef remains safe.
Looking for an extra measure of food safety? When beef is ground, there is a
miniscule risk that nerve tissue will accidentally be included. But solid
cuts of boneless meat are prion-free. So if you're looking for that extra
level of safety, buy whole cuts of beef and ask the butcher to grind them
for you.
