Nanoparticle proposed to lengthen food shelf-life: where’s the testing?

leave a comment »

The website Food Production Daily has a new article touting the benefits of nanotechnology in food products.

They write: “A modified nanoparticle from corn can be used to extend the shelf-life of food products and preserve their health benefits by delaying oxidation, according to new research.

Purdue University assistant professor Yuan Yao has adapted the phytoglycogen nanoparticle allowing it to attach to oils and emulsify them while also acting as a barrier to oxidation.”

A patent application has been filed, but no mention is made of safety testing or process oversight by those whose obligation it is to see that dangerous products are kept out of our food supply and marketplace.

Many in industry are anxious to jump on new products and rush them to market  in order to make a killing.  Little do these undereducated fools know just how literal that may turn out to be.

The live attenuated Swine flu vaccine has dangerous side-effects and is genetically unstable

The live attenuated swine flu vaccine intended for millions of children has dangerous side effects and is genetically unstable, risking generation of new pandemic strains should mass vaccinations go ahead.
Prof. Joe Cummins and Dr. Mae-Wan Ho

The swine flu vaccines being prepared for release to combat the current pandemic will be fast tracked without the usual clinical trials to ensure their safety. Five different companies were contracted to produce vaccines worldwide – Baxter International, GlaxoSmithKline, Novartis. Sanofi-Aventis and AstraZeneca – using a range of technologies from traditional chicken egg production to cell culture [1] ( Fast-tracked Swine Flu Vaccine under Fire , SiS 43).

Most of the vaccines will not contain live virus and will be delivered by injection. However AstraZeneca will produce a genetically engineered live attenuated vaccine through its global biologics unit, MedImmune, using cell culture or eggs [2]. The MedImmune vaccine will be used primarily for children, to be delivered as a nasal spray. The nasal spray vaccine against pandemic H1N1 influenza has been fast tracked for global distribution [3].

The live-attenuated vaccine appears more effective than the inactivated virus vaccine, but it resulted in significantly higher rates of severe adverse events. Furthermore, there is evidence that the live vaccine is highly genetically unstable in warm body cells and that has not been thoroughly evaluated in the children vaccinated .
