The Failure Mode and Effect Analysis (FMEA) model has been applied for the risk assessment of corn curl manufacturing. A tentative approach of FMEA application to the snacks industry was attempted in an effort to exclude the presence of GMOs in the final product. This is of crucial importance both from the ethics and the legislation (Regulations EC 1829/2003; EC 1830/2003; Directive EC 18/2001) point of view. The Preliminary Hazard Analysis and the Fault Tree Analysis were used to analyze and predict the occurring failure modes in a food chain system (corn curls processing plant), based on the functions, characteristics, and/or interactions of the ingredients or the processes, upon which the system depends. Critical Control points have been identified and implemented in the cause and effect diagram (also known as Ishikawa, tree diagram, and the fishbone diagram). Finally, Pareto diagrams were employed towards the optimization of GMOs detection potential of FMEA.  相似文献

Controversy surrounds the production and consumption of genetically modified organisms (GMOs). Proponents argue that GMO food sources represent the only viable solution to food shortages in an ever‐growing global population. Science reports no harm from GMO use and consumption so far. Opponents fear the potentially negative impact that GMO development and use could have on the environment and consumers, and are concerned about the lack of data on the long‐term effects of GMO use. We discuss the development of GMO food sources, the history of legislation and policy for the labeling requirements of GMO food products, and the health, environmental, and legal rationale for and against GMO food labeling. The Food and Drug Administration regulates food with GMOs within a coordinated framework of federal agencies. Despite mounting scientific evidence that GMO foods are substantially equivalent to traditionally bred food sources, debate remains over the appropriateness of GMO food labeling. In fact, food manufacturers have mounted a First Amendment challenge against Vermont's passage of a law that requires GMO labeling. Mandatory GMO labeling is not supported by science. Compulsory GMO labels may not only hinder the development of agricultural biotechnology, but may also exacerbate the misconception that GMOs endanger people's health. © 2015 Society of Chemical Industry  相似文献

The aim of this study was to evaluate the potential of terahertz (THz) spectroscopy to discriminate genetically modified (GM) and non‐GM organisms. In this study, eighty‐four sugar beet samples (thirty‐six GM sugar beets and forty‐eight of their parents, non‐GM ones) were investigated using terahertz time‐domain spectroscopy (THz‐TDS) system between 0.2 and 1.2 THz. Discriminant analysis (DA) based on principal component analysis (PCA) was used to discriminate sugar beet samples into two classes: GM organisms (GMOs) and non‐GMOs. Study results indicate that the DA method leads to an excellent classification. A total of 95.8% of the non‐GM samples were accurately classified, and no GM samples were misclassified, as there was 100% correctness. Results of this study demonstrate that THz spectroscopy combined with chemometrics techniques can provide a fast, nondestructive and reliable method to differentiate GMOs and non‐GMOs, which avoids time‐consuming, laborious and expensive sensory and chemical analyses.  相似文献

This paper describes the development, production, and testing of a high-throughput analytical system, i.e., a unique screening tool for the unequivocal simultaneous identification of all currently EU-approved and all unapproved genetically modified organisms (GMOs) known to the Community Reference Laboratory for GM Food and Feed (CRL-GMFF), established according to Regulation (EC) No 1829/2003. The rationale and comparative advantage of the strategy selected as well as the formulation, potentiality, and flexibility of the system are illustrated here. The approach, developed in response to the worldwide growing testing needs, allows the event-specific simultaneous detection of 39 single-insert GMOs and their derived stacked events. System performance (specificity, efficiency, etc) has been successfully confirmed by experimental testing conducted within the CRL-GMFF and in collaboration with European control laboratories. The limit of detection (LOD) has been determined to be at least 0.045% expressed in haploid genome copies, thus in full compliance with EU requirements for method LOD. The “real-time PCR-based ready-to-use multi-target analytical system for GMO detection” developed by the Joint Research Centre is the first analytical tool worldwide allowing the simultaneous detection of so many genetic modification events using event-specific targets.  相似文献

Biotechnology has enabled the modification of agricultural materials in a very precise way, thereby improving productivity and yields of economically important crops. There are a number of methods available for detecting genetically modified organisms (GMOs). In the present investigation, a qualitative PCR technique has been adopted in order to discriminate between genetically modified and non‐modified food products. The qualitative PCR assay employs primers specific for genetic elements that are used to generate genetically engineered agricultural crops. Two of the most common primers used for the detection of GMOs, 35S promoter and NOS 3′ terminator, have been tested over a panel of 24 food products purchased from the local market. The results indicated that, out of the 24 food products tested, three products gave positive results with the 35S promoter. The NOS 3′ primers gave negative results with all tested samples.

According to the European Regulations (EC) 1829/2003 and 1830/2003, products which are, consist of or contain GMOs should be labelled and traceable in each stage of production, processing and distribution. Only in cases where the GMO level is below 0.9% and this presence is due to accidental contamination or is technically unavoidable, no labelling is required. As it is very unclear how feed manufacturers have implemented these new regulations, a Belgian survey was held to evaluate the current situation at importer and feed production level. Several bottlenecks were encountered, at the level of acquisition of raw materials and at production level, such as carry over of GM with non-GM soy in the production lines. Next to this, some weaknesses in the analysis of GMOs were also revealed.  相似文献

Specific legislation in the EU and several other countries requires that foods containing genetically modified organisms (GMOs) should be approved and labelled. This has necessitated the development of methods for detection of such materials. For screening purposes these methods should preferably enable detection of several different GMOs. Here we present a simple, robust, qualitative, nineplex PCR method for event-specific detection of maize T25, GA21, TC1507, MON863, MON810, NK603, construct specific detection of BT176, BT11 and detection of the endogenous hmga maize reference gene. PCR is carried out with primers labelled with fluorescent groups and the amplicons are detected using fluorescence capillary electrophoresis. Using mixtures of DNA from different certified reference materials, the detection limit was determined to approximately 0.1% for each GMO. Good agreement was observed in 85 of 88 determinations when eleven food and feed samples were analysed using the multiplex PCR assay and compared to results from quantitative real-time 5′-nuclease PCR. Discrepancies were only observed for one GMO at or close to the detection limit. The presented method is therefore suitable for screening purposes for food and feed containing the most common maize GMOs.  相似文献

The ability to manipulate and customize the genetic code of living organisms has brought forth the production of genetically modified organisms (GMOs) and consumption of genetically modified (GM) foods. The potential for GM foods to improve the efficiency of food production, increase customer satisfaction, and provide potential health benefits has contributed to the rapid incorporation of GM foods into the American diet. However, GM foods and GMOs are also a topic of ethical debate. The use of GM foods and GM technology is surrounded by ethical concerns and situational judgment, and should ideally adhere to the ethical standards placed upon food and nutrition professionals, such as: beneficence, nonmaleficence, justice and autonomy. The future of GM foods involves many aspects and trends, including enhanced nutritional value in foods, strict labeling laws, and potential beneficial economic conditions in developing nations. This paper briefly reviews the origin and background of GM foods, while delving thoroughly into 3 areas: (1) GMO labeling, (2) ethical concerns, and (3) health and industry applications. This paper also examines the relationship between the various applications of GM foods and their corresponding ethical issues. Ethical concerns were evaluated in the context of the code of ethics developed by the Academy of Nutrition and Dietetics (AND) that govern the work of food and nutrition professionals. Overall, there is a need to stay vigilant about the many ethical implications of producing and consuming GM foods and GMOs.  相似文献

PCR-based methods are widely used in the European Union and in other countries for the detection, identification, and quantification of genetically modified organisms (GMOs). The preparation of good-quality DNA from plant samples for GMO detection can be a challenging task, particularly if the DNA will be used for quantitative analysis. Two DNA extraction methods, namely manual (NucleoSpin Food kit from Machery-Nagel) and high-throughput partially automated (NucleoMag Plant kit from Machery-Nagel) methods, which utilize different DNA separation principles, were used for the isolation of DNA from maize flour samples. Despite the higher DNA recovery obtained using the high-throughput isolation method, a lower PCR efficiency was achieved, most likely due to the presence of PCR inhibitors in the extracts. We found both DNA extraction methods suitable for GMO analysis.  相似文献

Although environment remained for a long time at the very top of most advanced countries governments’ agenda priorities, and a series of protocols like Montreal (1987), Kyoto (2002), Conference in Rio de Janeiro (1992) and legislations (White and Green Paper, 2001 and 1996, respectively) were put forward among others, the global awareness towards the environment continues to be at a very low level. The main problem towards enforcing legislation is the high cost invoked by most industries and municipalities. However, recent advances in remediation, composting, recycling technology have shown that waste treatment can result in high added value products (i.e. biodiesel, fertiliser) and advantageous to the environment as well. European Union (EU) legislation is currently considered one of the well‐compiled and strict legislations compared with other advanced countries (USA, Canada and Japan). Although food industries are not included in the highly polluting ones, their great volume of waste materials generated, makes imperative their undertaking actions in this direction. This review aims at presenting all the EU laws (from the waste management perspective) in connection with the food industries and their interactions with the environment and vice versa.  相似文献

The first part of this review on European Union (EU) legislation related to food industries–environment interactions deals with chemicals which, in their majority, make their way to food. Such substances are the pesticides and fertilizers the residues of which abound in many agricultural produces (both of plant or animal origin). Another crucial issue is the unintentional release of dioxins and furans through combustion. Detergents or sanitizers in conjunction with compounds considered hazardous or corrosive or flammable stand for other topics falling in the general category of chemicals employed in the food industry. The aim of this review is to cover all the current EU legislation in the field of chemicals (dioxins, furans, pesticides, biocides products, fertilizers, sanitizers) coming directly or indirectly in contact with food and their waste management by providing six comprehensive and easy‐to‐use tables, and a synopsis of the main points of the currently in force EU legislation.  相似文献

Currently, the Bundesamt für Verbraucherschutz und Lebensmittelsicherheit (BVL) is running the project ”Development of a German Molecular Register as a web-based software application”. The Molecular Register shall integrate regulatory, phenotypic and molecular information on GMO, and allow the use of established bioinformatics tools in support of the Competent Authorities in their responsibilities according to Directive 2001/18/EC and Regulations (EC) No 1829/2003 and (EC) No 1830/2003.  相似文献

At present, European legislation prohibits totally the use of processed animal proteins in feed for all farmed animals (Commission Regulation (EC) No. 1234/2003–extended feed ban). A softening of the feed ban for non-ruminants would nevertheless be considered if alternative methods could be used to gain more information concerning the species origin of processed animal proteins than that which can be provided by classical optical microscopy. This would allow control provisions such as the ban of feeding animals with proteins from the same species or intra-species recycling (Regulation (EC) No. 1774/2002). Two promising alternative methods, near-infrared microscopy (NIRM) and real-time polymerase chain reaction (PCR), were combined to authenticate, at the species level, the presence of animal particles. The paper describes the improvements of the real-time PCR method made to the DNA extraction protocol, allowing five PCR analyses to be performed with the DNA extracted from a single particle.  相似文献

Recently, the European Commission (EC) has published a proposal for a Council Regulation on the protection of animals at the time of killing. The proposed regulation will enhance the technical requirements of Directive 93/119/EC on the protection of animals at the time of slaughter or killing, which have not been amended since 1993. The main specific problems identified with the present EU legislation are the lack of harmonized methodology for new stunning methods, the lack of clear responsibilities for operators on animal welfare, the insufficient competence of personnel handling animals and insufficient conditions for the welfare of animals during killing for disease control purposes. The adoption of the “Hygiene Regulation Package”, which emphasizes the responsibilities of the food business operators on food safety, has also changed the legal environment for slaughterhouses. Furthermore, the first Community Action Plan on the Protection and Welfare of Animals, adopted by the EC in 2006, introduced new concepts such as the welfare indicators and the need for further research programs and centres of reference on animal welfare. Also, the European Food Safety Authority (EFSA) adopted two scientific opinions in 2004 and 2006 on the different stunning and killing methods to be used for main farm species either for slaughter for human consumption or for disease control purposes. The World Organization for Animal Health (OIE) in 2005 also adopted two international guidelines on the welfare of animals at slaughter. After presenting a picture of situation of meat sector in EU, the Author provides a broad overview on the regulatory situation and considers the legislative and scientific perspectives that lead the EC to draft new rules in this regard.  相似文献

Specific legislation in the EU requires that foods containing more than 0.9% of genetically modified organisms (GMOs) should be labelled. This has necessitated the development of methods for detection and quantification of such materials. Here we present a robust, quantitative, 9-plex PCR method for event-specific detection of maize TC1507, MON863, MON810, T25, NK603, GA21, construct specific detection of BT11, BT176 and detection of the endogenous hmga maize reference gene. The method is suitable for quantification in the 0–2% range with a detection limit of approximately 0.1%. PCR is carried out in two stages. In the first stage, bipartite primers containing a universal 5′-sequence and a GMO specific 3′-sequence are used. In the second PCR stage only a universal primer is used. Trypsin digestion between the first and second PCR stages enhances signal strength and reproducibility. Probes hybridising to the PCR amplicons are then labelled by primer extension and detected by fluorescence capillary electrophoresis. Good agreement was observed in 76 of 80 determinations when 10 food and feed samples were analysed using the multiplex PCR assay and compared to results from quantitative real-time 5′-nuclease PCR. The presented method is therefore suitable for quantification purposes for food and feed containing the most common maize GMOs.  相似文献
