Abstract
The purpose of this study was to develop a rapid method based on a real-time PCR assay designed to identify the presence of pufferfish in roasted fish fillet. Specific primers and probes were designed targeting Takifugu spp. and Lagocephalus spp., the most common genera in China. Specificity and sensitivity of this assay design were tested by using artificially spikes of pufferfish mixed in with other fish, such as Gadus and Thamnaconus septentrionalis,among others. Fifteen samples of retail roasted fish fillet and six samples from a 1999 poisoning event that occurred in Fujian province China were analysed for pufferfish. When the assay design was validated, no cross-reaction was observed between pufferfish and other species of fish. The limit of detection (LOD) was determined to be 0.001 ng pufferfish template, and the sensitivity of the method was 1%. Lagocephalus lunari was detected in six samples assayed from 1999 and no pufferfish was detected in the 15 retail roasted fish fillet samples tested. These results showed that the method was efficient for screening for pufferfish contamination in the roasted fish fillet and it could benefit public health protection by reducing the risk of tetrodotoxin poisoning.

Abstract
Biopiracy as "a silent disease" is hardly detectable because it does not leave traces frequently. The corporate hijacking of food is the most important health hazard in this era; giant commercial enterprises are using intellectual property rights to patent indigenous medicinal plants, seeds, genetic resources, and traditional medicines. The new era of biotechnology relies on the genes of living organisms as raw materials. The "Gene Rush" has thus become similar to that of the old "Gold Rush." Sri Lanka has been spotted in the top 34 biodiversity hotspots globally. Moreover, localized in the tropics, human generations in Sri Lanka have utilized the array of plant species for herbal treatments and treatment of diseases. Sri Lanka after its 30-year civil war is moving towards a solid growth and conservation of the environment which is a major component in a sustainable development where the conservation of biodiversity plays a significant role. In this paper, we present an overview of typical cases of global biopiracy, bioprospecting via introduction of cost-effective deoxyribonucleic acid (DNA) fingerprinting and international protocol with Private-Public-People Partnership concept as excellent forms of utilization of natural resources. We propose certain perspectives as scientists towards abolishing biopiracy and also to foster the fair utilization of natural resources; since the economy of most developing countries is agriculture based, the gross domestic product of the developing countries could be increased by enhanced bioprospecting via introduction of cost-effective DNA fingerprinting technologies and thus not being a pray of corporate hijacking."Biopiracy is biological theft; illegal collection of indigenous plants by corporations who patent them for their own use" (Vandana Shiva).

Abstract
The verification of authenticity and detection of food mislabeling are elements that have been of high importance for centuries. During the last few decades there has been an increasing consumer demand for the verification of food identity and the implementation of stricter controls around these matters. Fish and seafood are among the most easily adulterated foodstuffs mainly due to the significant alterations of the species' morphological characteristics that occur during the different types of processing, which render the visual identification of the animals impossible. Even simple processes, such as filleting remove very important morphological elements and suffice to prevent the visual identification of species in marketed products. Novel techniques have therefore been developed that allow identification of species, the differentiation between species and also the differentiation of individuals that belong to the same species but grow in different populations and regions. Molecular markers have been used during the last few decades to fulfill this purpose and several improvements have been implemented rendering their use applicable to a commercial scale. The reliability, accuracy, reproducibility, and time-and cost-effectiveness of these techniques allowed them to be established as routine methods in the industry and research institutes. This review article aims at presenting the most important molecular markers used for the authentication of fish and seafood. The most important techniques are described, and the results of numerous studies are outlined and discussed, allowing interested parties to easily access and compare information about several techniques and fish/seafood species.

Abstract
The addition or exchange of cheaper fish species instead of more expensive fish species is a known form of fraud in the food industry. This can take place accidentally due to the lack of expertise or act as a fraud. The interest in detecting animal species in meat products is based on religious demands (halal and kosher) as well as on product adulterations. Authentication of fish and meat products is critical in the food industry. Meat and fish adulteration, mainly for economic pursuit, is widespread and leads to serious public health risks, religious violations, and moral loss. Economically motivated adulteration of food is estimated to create damage of around € 8 to 12 billion per year. Rapid, effective, accurate, and reliable detection technologies are keys to effectively supervising meat and fish adulteration. Various analytical methods often based on protein or DNA measurements are utilized to identify fish and meat species. Although many strategies have been adopted to assure the authenticity of fish and meat and meat a fish products, such as the protected designation of origin, protected geographical indication, certificate of specific characteristics, and so on, the coverage is too small, and it is unrealistic to certify all meat products for protection from adulteration. Therefore, effective supervision is very important for ensuring the suitable development of the meat industry, and rapid, effective, accurate, and reliable detection technologies are fundamental technical support for this goal. Recently, several methods, including DNA analysis, protein analysis, and fat-based analysis, have been effectively employed for the identification of meat and fish species.

Abstract
In times of increasing globalization and the resulting complexity of trade flows, securing food quality is an increasing challenge. The development of analytical methods for checking the integrity and, thus, the safety of food is one of the central questions for actors from science, politics, and industry. Targeted methods, for the detection of a few selected analytes, still play the most important role in routine analysis. In the past 5 years, nontargeted methods that do not aim at individual analytes but on analyte profiles that are as comprehensive as possible have increasingly come into focus. Instead of investigating individual chemical structures, data patterns are collected, evaluated and, depending on the problem, fed into databases that can be used for further nontargeted approaches. Alternatively, individual markers can be extracted and transferred to targeted methods. Such an approach requires (i) the availability of authentic reference material, (ii) the corresponding high-resolution laboratory infrastructure, and (iii) extensive expertise in processing and storing very large amounts of data. Probably due to the requirements mentioned above, only a few methods have really established themselves in routine analysis. This review article focuses on the establishment of nontargeted methods in routine laboratories. Challenges are summarized and possible solutions are presented.

Abstract
Abstract The use of analytical methodologies based on DNA (e.g. PCR-RFLP) to determine the authenticity of different types of meat products after the initial labeling is pivotal to avoid fraudulent practices due to the increased rates of meat consumption. Our PCR-RFLP of mitochondrial 12S rRNA gene using restriction enzymes (AluI and ApoI) aimed to confirm the accuracy of the meat species labeling, based on fresh and processed meat collected in central markets along the main cities in the Amazonas Region (Bagua, Bagua Grande, Chachapoyas, Luya, Pedro Ruiz, Rodriguez de Mendoza). Our analyses qualitatively identified and differentiated three commercial species of fresh meat (bovine, porcine, ovine) and also found the substitution of goat by sheep meat. Regarding processed meat, its composition was uncertain and further analyses should be addressed to determine the meat origin. Monitoring using DNA-based analytical methods of meat trade is suggested to determine fraudulent practices, such as species substitution in markets along regions of Peru.

Abstract
The purpose of this work was to develop a PCR method for the identification of smoked paprika "Pimentón de la Vera" adulteration with paprika elaborated from varieties of pepper foreign to the la Vera region, in central western Spain. Three autochthonous varieties of pepper, Jaranda, Jariza, and Bola, and the varieties Papri Queen, Papri King, Sonora, PS9794, and Papri Ace, foreign to the La Vera region, were used in the study. Analyses of the ITS and 5.8S rDNA, RAPD-PCR, SSR, and ISSR were tested. RAPD-PCR, SSR, and ISSR analyses allowed differentiation among the varieties of paprika analyzed. There was no difference in the sequence of ITS1-5.8S rDNA-ITS2. In addition, with the RAPD-PCR primers S13 and S22, two molecular markers were obtained of 641 and 704 bp, respectively, which allowed all of the smoked paprika varieties to be differentiated from paprikas elaborated with the five foreign varieties. These two molecular markers were investigated as a basis for detecting the adulteration of smoked paprika with paprika elaborated from foreign varieties of pepper.

Abstract
Mitochondrial 16S rRNA sequences from morphological validated grouper (Epinephelus aeneus, E. caninus, E. costae, and E. marginatus; Mycteroperca fusca and M. rubra), Nile perch (Lates niloticus), and wreck fish (Polyprion americanus) were used to develop an analytical system for group diagnosis based on two alternative Polymerase Chain Reaction (PCR) approaches. The first includes conventional multiplex PCR in which electrophoretic migration of different sizes of bands allowed identification of the fish species. The second approach, involving real-time PCR, produced a single amplicon from each species that showed different Tm values allowing the fish groups to be directly identified. Real-time PCR allows the quick differential diagnosis of the three groups of species and high-throughput screening of multiple samples. Neither PCR system cross-reacted with DNA samples from 41 common marketed fish species, thus conforming to standards for species validation. The use of these two PCR-based methods makes it now possible to discriminate grouper from substitute fish species.

Abstract
The identification of fish species in food products is problematic because morphological features of the fish are partially or completely lost during processing. It is important to determine fish origin because of the increasing international seafood trade and because European Community Regulation 104/2000 requires that the products be labeled correctly. Sequence analysis of PCR products from a conserved region of the cytochrome b gene was used to identity fish species belonging to the families Gadidae and Merluccidae in 18 different processed fish products. This method allowed the identification of fish species in all samples. Fish in all of the examined products belonged to these two families, with the exception of one sample of smoked baccalà (salt cod), which was not included in the Gadidae cluster.

Abstract
A novel procedure for the authentication of frigate tunas (Auxis thazard and Auxis rochei) in commercially canned products has been developed. Three mitochondrial regions were simultaneously amplified by multiplex-Polymerase Chain Reaction, one corresponding to the small rRNA 12S subunit as a positive amplification control and two species-specific fragments corresponding to cytochrome b for A. rochei and ATPase 6 for A. thazard, respectively. Testing of two different detection systems revealed the fluorescence-based approach as the most sensitive. The results demonstrate that this rapid, low-cost methodology is a reliable molecular tool for direct application in the authentication of canned products.

Abstract
Canned truffle products labeled Tuber melanosporum, the famous Perigord truffle, may contain other less tasty and cheaper truffle species. To protect consumers from fraud, a PCR DNA-based method was used to unequivocally identify the nature of the product. Several rapid and simple cell lysis procedures, used in conjunction with a commercially available DNA purification kit, were evaluated for their effectiveness in recovering DNA from canned truffle. In parallel, a marker for T. melanosporum was tested on the mitochondrial rDNA. These two techniques were then combined to differentiate T. melanosporum from other truffle species like T. aestivum, T. brumale or T. indicum up to the legal threshold in canned products. These findings not only allow a comparison of the effectiveness of the different DNA extraction methods but also provide a preliminary indication of the specificity and sensitivity of the detection with the mitochondrial marker that might be attainable for truffle species in a quantitative PCR-based analysis method.

Abstract
Identification of fish species adulteration is important for consumer protection and the enforcement of food-labeling laws. A monoclonal antibody (MAb) generated against soluble muscle proteins from grouper (Epinephelus guaza) has been used in two indirect enzyme-linked immunosorbent assay (ELISA) formats (microtiter plates and immunostick tubes) for the rapid authentication of grouper fillets. The 3D12 MAb was produced with the use of the hybridoma technique and tested against several commonly consumed fish species by ELISA. The 3D12 MAb specifically reacted with grouper samples and could be useful for the discrimination of grouper among other, less-valued, fish species sold in the marketplace.
