Você Comeria Salmão transgênico? FDA Aprova Salmão Geneticamente Modificado

(…) Michael Hansen, um pesquisador da União dos Consumidores, explicou que o salmão transgênico pode causar reações alérgicas que o FDA é incapaz de prever. Peixes transgênicos também não poderão ser rotulados, deixando os consumidores no escuro sobre a sua origem.

Se o FDA não prestar atenção ao clamor público, o Congresso pode ainda evitar a comercialização do peixe transgênico. Wenonah Haute, diretor do Food & Water Watch, pede para que os consumidores contactem os seus deputados para derrubar o que tem sido chamado de “um experimento perigoso” às custas da saúde do consumidor.

Outras preocupações sobre o peixe transgênico diz respeito a capacidade deste superar o salmão natural do Atlântico. Se ele for solto na vida selvagem, o salmão AquAdvantage poderia se adaptar aos novos alimentos, sobreviver em habitats mais difíceis, e se reproduzir muito mais rápido que o salmão natural.

Andrew Kimbrell do Centro para a Segurança dos Alimentos concluiu que “o salmão geneticamente modificado não tem valor socialmente redentor. Ele é ruim para o consumidor, ruim para a indústria do salmão e ruim para o meio ambiente.”(…)

 

(NaturalNews) Depois de poucos e breves testes, o salmão transgênico, projetado para crescer duas vezes mais rápido que o salmão normal do Atlântico, foi considerado seguro para o ambiente e para o consumo humano. O FDA (a ANVISA dos EUA) acrescentou que ouviria comentários do público durante 60 dias, antes de finalmente decidir se aprova ou não o salmão.

As críticas a respeito da avaliação recente pelo FDA aponta para a falta de evidências suficientes de que o peixe é seguro para o consumo, e também da dificuldade em medir o impacto real sobre o meio ambiente uma vez que a produção em massa do salmão transgênico inicie.

De onde o salmão biotecnológico vem?

O controverso peixe é desenvolvido pela AquaBounty Technologies, uma pequena empresa de biotecnologia americana, cujo principal objetivo é encontrar a solução que poderia aumentar a produtividade da aquicultura. Sua pesquisa mais importante consiste em desenvolver
    salmão, truta, e ovos de tilápia que produzem  espécimes de rápido desenvolvimento. Para conseguir isso, os pesquisadores modificaram a estrutura genética do peixe. Sua variedade de salmão foi patenteada e recebeu o nome de Salmão AquAdvantage.

O relatório do FDA  afirma que “no que diz respeito à segurança dos alimentos, a FDA concluiu que alimentos feitos com o Salmão AquAdvantage são tão seguros quanto aqueles feitos com o salmão convencional do Atlântico, e que existe certeza razoável de que não existe nenhum prejuízo de seu consumo“.

O que dizem os críticos?

Would you eat biotech fish? FDA approves genetically engineered salmon

(NaturalNews) After a few brief tests, GE salmon, meant to grow twice as fast as regular Atlantic salmon, was deemed safe both for the environment and for human consumption. The FDA added that it would take public comments for 60 days before finally deciding on whether or not to approve the salmon.

Criticism of the recent FDA assessment points to the lack of sufficient evidence that the fish is safe for consumption, and the difficulty in measuring its real impact on the environment once mass production begins.

Where does biotech salmon come from?

The controversial fish is developed by AquaBounty Technologies, a small American biotechnology company whose main goal is to find solutions that could increase the productivity of aquaculture. Its most important research consists of developing salmon, trout, and tilapia eggs that produce fast growing specimens. To achieve this, researchers have to modify the very genetic fabric of fish. Their salmon variety has been patented and bears the trade name AquAdvantage Salmon.

The FDA report so far states that “with respect to food safety, FDA has concluded that food from AquAdvantage salmon is as safe as food from conventional Atlantic salmon, and that there is a reasonable certainty of no harm from consumption.”

What the critics say

Michael Hansen, a researcher at the Consumers Union, explained that GE fish could cause allergic reactions that the FDA is unable to anticipate. GE fish will also likely not be labeled accordingly, leaving consumers in the dark about where the fish is coming from.

If the FDA does not heed the public outcry, Congress could still prevent the commercialization of GE fish. Wenonah Hauter, director at the Food & Water Watch, urges consumers to contact their congressmen to overturn what has been called “a dangerous experiment” at the expense of consumer health.

Other concerns about GE fish pertain to its ability to outcompete natural Atlantic salmon. If it is released into the wild, the AquAdvantage salmon could adapt to new pray, survive in tough habitats, and reproduce much faster than its natural counterpart.

Andrew Kimbrell of the Center for Food Safety concluded that “the GE salmon has no socially redeeming value. It’s bad for the consumer, bad for the salmon industry and bad for the environment.”

Healthy, vegan alternatives to GE salmon

Chickpeas have been hailed by vegans everywhere for their ability to mimic fish, making them an excellent addition to faux fish salads. Chickpeas provide considerable amounts of protein, slow release carbohydrates, folate and zinc.

A delicious vegan “salmon” dish can be prepared by mixing grated carrots, mashed chickpeas, white vinegar, tomatoes, finely grated lemon peel, lemon juice, dill, vegetable oil and a pinch of salt. The mixture can either be consumed raw, or divided into patties and baked for about 25 minutes. For added flavor, vegan “salmon” can be topped with vegan mayonnaise or grated horseradish.

When choosing salmon as a means to obtain healthy fats, many may want to consider chia instead. With 724 mg of Omega-3’s in 28 grams of salmon, and 4915 mg in 28 grams of chia, chia is a clear winner.

Tem arsênico no seu arroz. There’s arsenic in your rice — and here’s how it got there

Rice. It’s just one of the basics, right? Whether eaten on its own, or in products like pastas or cereal, this inexpensive and healthy food is a staple for Asian and Latino communities, as well as the growing number of people looking to avoid gluten.

Here’s the bad news (cue Debbie Downer sound effect): The food most of us think we have more or less locked down is shockingly high in arsenic. And arsenic, especially the inorganic form often found in rice, is a known carcinogen linked to several types of cancer, and believed to interfere with fetal development.

According to new research by the Consumers Union, which took over 200 samples of both organic and conventionally grown rice and rice products, nearly all the samples contained some level of arsenic, and a great deal of them contained enough to cause alarm. While there is no federal standard for arsenic in food, according to the Consumers Union, the advocacy arm of Consumer Reports, one serving of rice may have as much inorganic arsenic as an entire day’s worth of water.  (They’ve also created a useful chart of various rice products, rice brands, and their arsenic levels.)

How does rice compare to other grains like wheat and oats? It turns out it’s much higher because of two main factors: How and where rice is grown. The November issue of Consumer Reports, released today, breaks down both phenomena. First, the how:

Rice absorbs arsenic from soil or water much more effectively than most plants. That’s in part because it is one of the only major crops grown in water-flooded conditions, which allow arsenic to be more easily taken up by its roots and stored in the grains.

Then, the where:

In the U.S. as of 2010, about 15 percent of rice acreage was in California, 49 percent in Arkansas, and the remainder in Louisiana, Mississippi, Missouri, and Texas. That south-central region of the country has a long history of producing cotton, a crop that was heavily treated with arsenical pesticides for decades in part to combat the boll weevil beetle.

Not a big rice eater? Well, I’d argue this study matters for other reasons too; it illustrates what a long shadow industrial farming practices can cast over the entire food system — and the way some chemicals can cycle through our food and water, for literally generations. You see, in some areas, even rice grown organically is impacted because of what you might call the legacy of the soil.

For decades, farmers used lead-arsenate insecticides to control pests. As the name implies, these were extra dangerous because of their lead content and they were banned in the 1980s, but much of the arsenic that was left behind still remains in the soil. As Consumer Reports mentioned above, the worst offenders were cotton farms in the South, which relied heavily on these heavy-metal-containing chemicals. (Cotton farming, generally, is known to be some of the most “chemically dependent” farming on Earth.)

There are still several non-lead-based arsenical pesticides on the market, and although most are in the process of being phased out, Michael Hansen, Consumers Union senior scientist, says there is still one important pesticide, called MSMA, in use on cotton farms. Ironically, Hansen says, “they’re allowing its use because of the increasing problem of Palmer pigweed — created by the overuse of Glyphosate [Roundup] due to [Roundup Ready] GMO seeds.” (Otherwise known as superweeds.) “Palmer pigweed can lead to a 25 percent-or-more loss of revenue in cotton. So federal regulators calculated that it was worth the risk to continue using arsenic herbicides.”

Arsenic has also been commonly used in animal feed to prevent disease and make both hogs and chickens grow faster. The manure from these farms also ultimately ends up adding arsenic back in the soil (it’s even permitted on organic farms). Hansen says he’s seen ample evidence that soils that have been treated with poultry manure for years “have significantly higher levels of arsenic than untreated soil.”

On the bright side, a new law in Maryland, a huge poultry farming state, will keep arsenic feed out of chicken farms there. And one poultry drug, Pfizer’s Roxarsone, was voluntarily withdrawn from the market last spring. Meanwhile there are three others are still allowed to be used outside Maryland. “We think the Food and Drug Administration [FDA] should ban those as well,” said Hansen.

In the press release associated with the study, Consumers Union recommended that the Environmental Protection Agency (EPA) phase out use of all arsenical pesticides and the FDA set limits for arsenic in rice products. In response to Wednesday’s report, the FDA released an FAQ on its website describing its own testing of 1,000 different rice products. FDA officials also told the Washington Post, however, that they are “not prepared, based on preliminary data, to advise people to change their eating patterns.”

The Consumers Union, on the other hand, has a released a chart explicitly designed to help consumers limit their exposure to rice, with exact serving recommendations for both adults and children. Rice cereal, which federal surveys indicate many small children eat multiple times a day, is of special concern.

According to Hansen, rice grown in California (a relatively small subset of the U.S. industry), is also likely to have lower arsenic rates than rice grown in the South. For those interested in reducing their risk, the scientist also recommends washing the grain thoroughly before cooking it, and using a technique Hansen has observed in Asia.

“When I was in Bangladesh recently I noticed they would cook the rice with a lot of extra water — to absorb arsenic and/or pesticide residue — and then drain it off at the very end before serving it.” Hansen says this technique, over time, especially if filtered water is used, may reduce the risk of exposure to the heavy metal.
