“…This should not come as a surprise, taking into account that this variety was and still is the most-grown GM soybean event globally. The presence of MON40-3-2 is common in food and feed in many countries, according to reports of other authors (1,3,6,10,13,15,20,22,24,25,26,28,31,32). Its presence in feed on the Polish market may also be traced back to member states of the EU, other European countries, and third countries like Ukraine, which export soybean within and to the EU.…”

Introduction Globally, genetically modified (GM) crops were grown on 191.7 million hectares in 2018, which were mostly sown with soybean, maize, cotton, oilseed rape, and rice. The most popular traits introduced through genetic modification include herbicide and pest insect resistance. The aim of this study was to identify and quantify genetically modified soybean used in animal feed in Poland. Material and methods This research was based on the real-time PCR technique. All methods for GM soybean events were adopted from the EURL GMFF database of methods and previously verified to meet the minimum criteria of acceptance. Over 15 years of research, 665 samples were examined in total. Results The most common GM soybean event was MON40-3-2, tested for from the beginning of the investigation. Next, in decreasing order of frequency, were MON89788, MON87701, and A2704-12. In the majority of samples (606; 91%) GM soybeans were identified at a content level above the 0.9% GM content threshold for mandatory labelling. Only 59 soybean samples (9%) were identified as GM negative. GM negative results were mainly identified during the analyses in the last three years of the study, from 2017 to 2019. Conclusion Our data clearly indicate that the majority of soybean used in Poland for animal feeding was genetically modified.

“…By 2016, China had approved 60 genetically modified (GM) crop events for food and feed use 19 . Of the GM soybean events, GTS40-3-2, MON89788 and A2704-12 are the most imported transgenic soybean lines in China 20 . Soybean powder is commonly added to ham sausage as a raw material because its addition makes the structure of the sausage tight and elastic, as well as rendering the cut surface smooth.…”

Presently, there is growing concern worldwide regarding the adulteration of meat products. However, no reports on determining meat authenticity have been reported in China. To verify labelling compliance and evaluate the existence of fraudulent practices, 250 sausage samples were purchased from local markets in Sichuan Province and analysed for the presence of chicken, pork, beef, duck and genetically modified soybean DNA using real-time and end-point PCR methods, providing a Chinese case study on the problem of world food safety. In total, 74.4% (186) of the samples were properly labelled, while the other 25.6% (64) were potentially adulterated samples, which involved three illicit practices: product removal, addition and substitution. The most common mislabelling was the illegal addition of, or contamination with, duck. Therefore, meat authenticity monitoring should be routinely conducted. Additionally, the strict implementation of the nation’s food safety laws, along with regular surveillance, should be compulsory to alleviate and deter meat adulteration.
