Genetically modified yeast has been related to increase in headaches and allergies. Make sure you contact the vineyard or the wine maker before purchasing the wine, if you want to make sure they aren't using GMO yeast. Cassava Cassava is a starchy plant like potato that is consumed by many people across the globe like Africa.
Iran J Pharm Res. Due to the increasing number of GMOs imported to Iran during the past few years, it has become necessary to screen the products in order to determine the identity of the consumed daily foodstuffs. In this study, following the extraction of genomic DNA from processed foods sold commercially in Iran, qualitative PCR was performed to detect genetically modified maize.
Based on the gel electrophoresis results, Bt- 11 and MON events were detected in some maize samples, while, in none of them Bt- modified gene was detected. For the first time, the results demonstrate the presence of genetically modified maize in Iranian food products, reinforcing the need for the development of labeling system and valid quantitative methods in routine analyses.
Introduction Genetic modification has been an extremely valuable tool in plant genetic research.
The genetically modified organism GMO contains an exogenous gene which is able to express a new protein that confers new traits, i. Many genetically modified crops have been approved worldwide since mids and the global area of these crops has expanded yearly since their commercialization.
Inmillion hectares were cultivated with genetically modified crops mainly soybean, maize, cotton and canola 34. Therefore, the detection and identification of GMOs in food have become important issues for all the subjects involved in food control 9 Qualitative testing may be used to discriminate between the authorized and unauthorized GM food to identify safe or potentially unsafe material 11 Although several analytical methods have been proposed, GMO detection methods generally involve specific DNA sequence detection by means of PCR techniques, able to detect even small amounts of transgenes in raw materials and processed foods 13 In this study, we examined the detection of recombinant DNA of genetically modified maize in several processed foodstuffs gathered from Iranian market.
This method includes the following steps: From reference material Appropriate reference materials for positive and negative controls provide the basis for the validation of analytical procedures The following commercially available Certified Reference Materials were used: From processed food samples In total 25 food samples including a variety of processed material, from relatively mild treated maize to highly processed products containing maize ingredients, for human consumption were gathered randomly from different Iranian supermarkets.
The analyzed products were as follows: Oligonucleotide primers Oligonucleotide primers were purchased as purified and desalted specimen from Eurofins. The sequences of oligonucleotide primers are given in Table 1.Detection of Genetically Modified Maize by the Polymerase Chain Reaction and Capillary Gel Electrophoresis with UV Detection and Laser-Induced Fluorescence Virginia García-Cañas, Ramón González, and Alejandro Cifuentes *.
In the government of Mexico created a regulatory pathway for genetically modified maize, but because Mexico is the center of diversity for maize, gene flow could affect a large fraction of the world's maize strains.
A report in Nature presented evidence that Bt maize was cross-breeding with unmodified maize in Mexico.

In , the global cultivation area of genetically modified (gm) crops increased to million hectares (estimation) worldwide (James, ). Besides gm soybean, gm maize is the most important biotech crop, cultivated on more than 60 million hectares. 1. Vet Hum Toxicol. Mar;45(2) Detection of genetically modified maize DNA fragments in the intestinal contents of pigs fed StarLink CBH To address this issue, it is necessary to detect genetically modified (GM) maize and establish a monitoring and regulatory system in Nepal. Currently, Nepal does not have legal regulations.
The debate over labeling genetically modified organisms still continues in US while 27 different countries have banned GMOs and 50 countries across the globe have requited GMO plombier-nemours.com voters in California will make the final decision this November to label plombier-nemours.comile customers should be aware of the food products .
