USDA Has Given Non-Regulated Status to More than 20 Gene-Edited Crops – New Report

Posted on Mar 14 2019 - 4:00pm by Sustainable Pulse

According to new research carried out by Testbiotech, the United States Department of Agriculture (USDA) has already given non-regulated status to more than 20 plants genetically engineered with so-called genome editing techniques. None of the applications registered at the USDA were referred for further more detailed assessment.

The Testbiotech report published today shows that there are however significant differences in methods of production, traits and risks of the non-regulated plants in comparison to those derived from conventional breeding.

These differences are not caused by the newly introduced gene sequences but by e.g. the patterns of genetic changes. ‘Gene-scissors’ such as CRISPR/Cas can delete whole families of gene variants all at once – this is either impossible or barely possible with current conventional breeding methods. A further specific difference: in a first step, older methods such as the ‘gene gun’ (biolistic method) or gene transfer via agrobacterium tumefaciens are commonly used. However, the USDA completely ignores these differences to conventional breeding.

The plant species listed include pennycress, green foxtail, potatoes, camelina, alfalfa, maize (corn), rice, soybeans, tobacco, tomatoes and wheat and one mushroom. The exact intended traits of the plants cannot always be precisely determined. In many of the registered documents no information is provided because the precise description of the targeted genes is categorized as confidential business information (CBI). It is also sometimes difficult to find information on the progress of developments – it does however appear that applications are filed at early stage. Generally, it has to be assumed that by no means will all of the plants registered come on to the market. On the other hand, some companies have announced to investors that some specific plants will be on the market very soon.

Essentially, conventional breeding is always based on a wide range of genetic and biological diversity found in natural populations, as well as in all previously bred plant and animal varieties and breeds. In addition, new mutations happen continually and specific triggers can speed up the occurrence of mutations. Not all of these mutations are considered beneficial. In order to achieve the desired results, breeders screen natural populations and previously bred varieties for specific traits. Subsequently, plants are chosen and then grown and crossed to achieve an optimal combination of genetic information. The natural mechanisms of inheritance and gene regulation cannot be bypassed with this method.

Genetic engineering on the other hand uses direct technical and targeted intervention to establish new traits. These technical interventions bypass natural biological mechanisms governed by evolution, inheritance and gene regulation, and can therefore be much faster than conventional breeding. Since genetic engineering intervenes directly in the genome, the resulting plants and animals can be very different to those from conventional breeding. Therefore, it is necessary to treat these organisms with caution before any environmental releases take place or they are approved for use in food production.

In the EU, all genetically engineered organisms must undergo a mandatory risk assessment. In the USA, on the other hand, there are no such legal requirements. There are nevertheless also stakeholders in the EU who want to market their products as quickly as possible. Their goal: plants and animals and related products developed with new genetic engineering techniques should be released without undergoing an approval process and sold without labeling.

If however the new plants are marketed without regulation or approval process, then neither farmers nor gardeners would know what he/she is actually cultivating. The plants could also be crossed and combined with others, without combinatorial effects being investigated in detail. Consumers would lose their freedom of choice since they would no longer be able to distinguish whether the products were genetically modified or not. Even the authorities would not know which plants were imported from which countries, and what they would have to look for if there was in fact harm to people or the environment.

Christoph Then summarized the Testbiotech findings: “The risks of genetically engineered organisms have to be assessed in each and every case. Moreover, if organisms are known to show potential for environmental spread or might develop such characteristics, efficient measures and restrictions have to be put in place to prevent gene flow.”

    What are the 20 CRSPR crops that were approved so we can avoid these unlabeled Frankenfood mutants?
    East Organic food to avoid these freak foods.

    the ??? with Monsanto G M O products is everything should be avoided . till we know for sure what to be expected from the out come of any food products period that they have tested with . that would include any so called chemicals that has been developed , we are not to be as one would say to be there ginniepigs to be test on us .
