China has recently made headlines with stories of food producers using toxic or fake ingredients in their food such as plastic rice and fake green peas.
Now Vietnam is making the front pages. Vietnamese producers have been caught exporting shrimp injected with chemicals to make the product weigh more — yes, it is all about the money.
A video report shows one supplier using 30 chemical pumps to inject each shrimp with a combination of the following:
- CMC (Carboxymethyl cellulose)
Why is this done?
In simple terms, it brings the vendor more money. For example, 1 kg (2.2 lbs) will weight about 1.15-1.2 kg after the injection. It also makes the shrimp “looks fresher,” according to the video. The fresh look allows the vendor to increase the price.
The facility worker confessed:
Every day I buy around 30-50 kg of shrimp. After I inject the substances, I sell them to seafood export companies in Ca Mau, Vietnam. I have to do this because all local shrimp suppliers do this.
The owner said the company buys the chemical CMC to inject shrimp with from China. Because CMC becomes a clear gel-like substance when dissolved in water, it matches the consistency of a shrimp’s body.
What is CMC?
CMC or Carboxymethyl cellulose, is a “water-soluble anionic linear polymer” used as a food additive, as well as in pharmaceuticals and cosmetics.
Different types of CMC are available: purified (food grade), technical grade and industrial. The food grade is 99.5% or higher, and is called cellulose gum. The FDA labeled it GRAS (Generally Recognized as Safe), however no new studies have been done since 1970s to confirm that it is indeed harmless. What we currently know is that consuming large amounts of CMC can potentially lead to diarrhea and abdominal cramps.
Unfortunately, we do not know that the CMC Vietnam gets from China is food grade. Knowing that this whole scheme is to make money, it is quite likely that many vendors will order the cheapest CMC they can find; industrial grade is twice cheaper than food grade, and it is 50-90% pure. It contains large amounts of sodium chloride and sodium glycolate. These two ingredients are not recommended for people with heart problems, high blood pressure, and sodium-sensitivity.
Although some studies suggest that the chemical is not toxic in low levels, [newer studies are needed], it is hard to say how much CMC the person is consuming when eating this shrimp form Vietnam.
And if it is injected with industrial grade CMC, people who are watching their sodium intake should be extra careful when eating shrimp.
