Abstract
The degradation of ingredients in heat-processed meat products makes their authentication challenging. In this study, protein profiles of raw beef, chicken, duck, pork, and binary simulated adulterated beef samples (chicken-beef, duck-beef, and pork-beef) and their heat-processed samples were obtained by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Heat-stable characteristic proteins were found by screening the overlapping characteristic protein ion peaks of the raw and corresponding heat-processed samples, which were discovered by partial least-squares discriminant analysis. Based on the 36 heat-stable characteristic proteins, qualitative classification for the raw and heat-processed meats was achieved by extreme gradient boosting. Moreover, quantitative analysis via partial least squares regression was applied to determine the adulteration ratio of the simulated adulterated beef samples. The validity of the approach was confirmed by a blind test with the mean accuracy of 97.4%. The limit of detection and limit of quantification of this method were determined to be 5 and 8%, respectively, showing its practical aspect for the beef authentication.

Abstract
A hexaplex-conventional PCR assay was developed for identification of five meat and one plant species origins in foodstuffs simultaneously. The method merges the use of horse (Equus caballus), soybean (Glycine max), sheep (Ovis aries), poultry (Meleagris meleagris), pork (Sus scrofa), and cow (Bos taurus) specific primers that amplify fragments (horse; 85 bp, soybean; 100 bp, sheep; 119 bp, poultry; 183 bp, pork; 212 bp and cow; 271 bp) of the mitochondrial cyt b, lectin, 12S rRNA, 12S rRNA, ATPase subunit 6 genes and ATPase subunit 8 genes respectively, and a universal 18S rRNA primers that amplifies a 141 bp. Multiplex analysis of the reference food samples showed that detection limit of the hexaplex assay was 0.01% for each species. Taken together, all data indicated that this hexaplex PCR assay was a simple, fast, sensitive, specific, and cost-effective detection method for horse, soybean, sheep, poultry, pork and cow species in foodstuffs.

Abstract
A method for the detection and identification of "prohibited" mammalian or avian material in animal feed was developed and assessed through the analysis of DNA. A generic real-time PCR assay was designed to detect the presence of mammalian and avian mitochondrial DNA 16S rRNA genes in animal feed samples. Samples positive with this screening method were further investigated using identification assays to detect the 16S rRNA gene from bovine, ovine, porcine, and avian species and to determine whether the DNA originated from species whose material is prohibited from inclusion in farmed animal feed. An internal positive control was coamplified in the 16S real-time PCR assays to monitor PCR amplification efficiency and avoid potential false-negative results. Using vegetable-based feed standards spiked with meat and bone meal generated with a commercial rendering process, 0.1% meat and bone meal could be detected using the general and species-specific 16S assays. The species-specific assays had 100% specificity for the homologous target species. The 16S real-time PCR assays were evaluated alongside existing tests based on protein evaluation or microscopic examination for a wide range of commercial animal feed samples. In total, 111 (0.76%) of 14,678 samples examined contained prohibited material based on the results from at least one of these tests. However, most positive results did not represent noncompliance because they were associated with samples of pet food, which can legitimately contain material prohibited for use in food for farmed animals. The species-specific 16S assays confirmed the presence of prohibited material in 75% of the 111 samples, whereas the existing protein and microscope tests confirmed the presence of this material in 25 and 54% of the samples, respectively.

Abstract
A real-time PCR approach with the SYBR Green detection system has been developed for the quantitative detection of bovine tissues in food and feedstuffs. The method combines the use of bovine-specific primers, which amplify an 84-bp fragment of the mitochondrial 12S rRNA gene, and universal primers, which amplify a 140-bp fragment of the nuclear 18S rRNA gene from eukaryotic DNA. The 18S rRNA primers are used as endogenous controls for the total content of PCR-amplifiable DNA in the sample. The specificity of the primers was tested against 18 animal species, including mammals, birds, and fish, as well as 6 plant species. Analysis of experimental bovine tissues-oats mixtures demonstrated the suitability of the assay for the detection of bovine DNA in mixtures containing as low as 0.1% of bovine tissues. The performance of the method is not affected by severe heat treatment (up to 133 degrees C for 20 min at 300 kPa). The reported PCR assay could be very useful for detecting bovine-derived ingredients in raw and heat-treated food and feedstuffs.

Abstract
The commercialization of animal feeds infected by prions proved to be the main cause of transmission of bovine spongiform encephalopathy (BSE). Therefore, feed bans were enforced, initially for ruminant feeds, and later for all feeds for farmed animals. The development and validation of analytical methods for the species-specific detection of animal proteins in animal feed has been indicated in the TSE (Transmissible Spongiform Encephalopathies) Roadmap (European Commission. The TSE (Transmissible Spongiform Encephalopathy) roadmap. URL: http://europa.eu.int/comm/food/food/biosafety/bse/roadmap_en.pdf, 2005) as the main condition for lifting the extended feed ban. Methods based on polymerase chain reaction (PCR) seem to be a promising solution for this aim. The main objective of this study was to determine the applicability of four different real-time PCR methods, developed by three National expert laboratories from the European Union (EU), for the detection and identification of cattle or ruminant species in typical compound feeds, fortified with meat and bone meals (MBM) from different animal species at different concentration levels. The MBM samples utilized in this study have been treated using the sterilization condition mandatory within the European Union (steam pressure sterilization at 133 degrees C, 3 bar, and 20 min), which is an additional challenge to the PCR methods evaluated in this study. The results indicate that the three labs applying their PCR methods were able to detect 0.1% of cattle MBM, either alone or in mixtures with different materials such as fishmeal, which demonstrates the improvement made by this technique, especially when compared with results from former interlaboratory studies.

Abstract
UNLABELLED The feeding of ruminant proteins to ruminants is prohibited in most countries because the practice is thought to be responsible for the spread of bovine spongiform encephalopathy. However, currently available methods to detect ruminant blood products in rendered feedstuffs are inadequate because they lack species specificity, tissue specificity, and are not based on a thermostable analyte. A sandwich enzyme-linked immunosorbent assay (ELISA) was developed for this study that provides reliable and sensitive (0.05-0.5% v/v) detection of bovine blood materials in animal feed. The new sandwich ELISA employs two previously developed monoclonal antibodies (MAbs), Bb6G12 as the capture antibody and biotinylated MAb Bb3D6 as the detecting antibody, and is bovine-specific and blood-specific. The assay is based on the detection of a 60 kDa thermostable protein in bovine blood and provides a useful regulatory tool for monitoring fraudulent labeling or contamination of bovine blood in both heat-processed feedstuffs and unprocessed raw materials.

Abstract
To control the spread of bovine spongiform encephalopathy in cattle through contaminated animal feedstuffs, screening of feed products is essential. We designed five pairs of primers to identify specifically raw and heat-treated tissue from cattle, sheep, goat, deer, and ruminants in general. A forward common primer was designed based on a conserved DNA sequence in the mitochondrial 12S rRNA-tRNA(val)-16S rRNA gene, and reverse primers were designed to hybridize with a species-specific DNA sequence for each species considered. All primers were developed to create a specific PCR product small enough (less than 200 bp) to be suitable for heat-treated material. To evaluate the effect of heat treatment, a severe sterilization condition (133 degrees C at 300 kPa for 20 min) was chosen. Species-specific amplicons were obtained from all types of heat-treated meat meals. Analysis of laboratory-contaminated vegetable meals revealed that the detection limit of the assay was 0.05% for each species analyzed. This PCR-based analysis can be used as a routine method for detecting banned animal-derived ingredients in raw and heat-treated feedstuffs.

Abstract
This study describes a method for quantitative and species-specific detection of animal DNA from different species (cattle, sheep, goat, swine, and chicken) in animal feed and feed ingredients, including fish meals. A quantitative real-time PCR approach was carried out to characterize species-specific sequences based on the amplification of prion-protein sequence. Prion-protein species-specific primers and TaqMan probes were designed, and amplification protocols were optimized in order to discriminate the different species with short PCR amplicons. The real-time quantitative PCR approach was also compared to conventional species-specific PCR assays. The real-time quantitative assay allowed the detection of 10 pg of ruminant, swine, and poultry DNA extracted from meat samples processed at 130 degrees C for 40 min, 200 kPa. The origin of analyzed animal meals was characterized by the quantitative estimation of ruminant, swine, and poultry DNA. The TaqMan assay was used to quantify ruminant DNA in feedstuffs with 0.1% of meat and bone meal. In conclusion, the proposed molecular approach allowed the detection of species-specific DNA in animal meals and feedstuffs.

Abstract
An immunoassay system was developed for efficient detection of prohibited meat and bone meal (MBM) in animal feed. Monoclonal antibodies (MAbs) were raised against bovine smooth muscle autoclaved at 130 degrees C for 20 min. Among the 1,500 supernatants of hybridoma cells screened, MAbs 3E1, 1G3, and 3E10 were selected and characterized in this study. The first set of MAbs produced, 3E1 and 1G3, had stronger reactivity against MBM than against smooth muscle that was heat treated at 90 degrees C for 10 min. However, reactivity gradually increased against smooth muscle that was autoclaved at 130 degrees C for up to 1 h. The enzyme-linked immunosorbent assay for detection of MBM in animal feed was optimized with the MAb 3E10 because of its superior performance. MAb 3E10 diluted to 100-fold was used to differentiate bovine MBM from that of other species in ingredients used for commercial animal feeds and could detect down to 0.05% MBM mixed in animal feed.

Abstract
A sensitive and rapid method for the quantitative detection of bovine-, ovine-, swine-, and chicken-specific mitochondrial DNA sequences based on real-time PCR has been developed. The specificity of the primers and probes for real-time PCR has been tested using DNA samples of other vertebrate species that may also be present in rendered products. The quantitative detection was performed with dual-labeled probes (TaqMan) using absolute quantification with external standards of single species meat-and-bone meals. This method facilitates the detection of 0.01% of the target species-derived material in concentrate feed mixtures and fish meals.

Abstract
A duplex Polymerase Chain Reaction (PCR) method able to detect bovine milk in ovine cheeses was developed. This method is based on the mitochondrial 12S and 16S rRNA genes to generate fragments of different lengths. The proposed methodology presents an alternative DNA extraction procedure faster and more economical than the kits commercially available. A linear normalized calibration curve was obtained between the log of the ratio of the bovine band intensity and the sum of bovine and ovine band intensities versus the log of cow's milk percentage. The method was applied successfully to the detection and quantification of raw, pasteurized, and powdered bovine milk in different cheeses. The proposed duplex PCR provides a simple, sensitive, and accurate approach to detect as low as 0.1% bovine milk in cheeses and to quantify bovine milk in ovine cheeses in the range of 1-50%.

Abstract
A PCR-ELISA technique was developed for the semiquantitative detection of Nile perch (Lates niloticus) in experimentally sterilized fish muscle mixtures. Specific oligonucleotides derived from the 5S rDNA gene of Nile perch were selected. A forward primer, together with a reverse digoxigenin-labeled primer, permitted the amplification of specific 185 bp DNA fragments showing DNA intensities proportional to the contents of Nile perch muscle tissue in the fish mixtures. A biotinylated probe immobilized onto streptavidin-coated microplates was used to capture the digoxigenin-labeled fragments that were detected with peroxidase antidigoxigenin conjugate. Subsequent enzymatic conversion of substrate gave distinct absorbance differences when assaying fish binary mixtures containing different percentages of Nile perch muscle.

Abstract
A multiplex Polymerase Chain Reaction (PCR) assay was applied to feedstuff analysis for the identification of the most used species in rendering plants (ruminant, poultry, fish and pork materials). Primers were designed in different regions of mitochondrial DNA (12S rRNA, tRNA Val and 16S rRNA) after alignment of the available sequences in the GenBank database. The primers generated specific fragments of 104-106, 183, 220-230 and 290 bp length for ruminants, poultry, fish and pork, respectively. The detection limit was 0.004% for fish primers and 0.002% for ruminants, poultry and pork primers. The multiplex PCR proposed in this study can be considered a valid alternative to the microscopic method for the detection of animal derived materials banned by a European Union Regulation as a preventive measure against the spread of Bovine Spongiform Encephalopathy.

Abstract
A real-time quantitative Polymerase Chain Reaction (PCR) method has been developed for the quantitation of mule duck (Anas platyrhynchos x Cairina moschata) in binary duck/goose foie gras mixtures. The method combines the use of real-time PCR with duck-specific and endogenous control "duck + goose" primers to measure duck content and total foie gras content, respectively. Both PCR systems (duck-specific and duck + goose) were designed on the mitochondrial 12S ribosomal RNA gene (rRNA). The duck-specific system amplifies a 96 bp fragment from duck DNA, whereas the duck + goose system amplifies a 120 bp fragment from duck and goose DNA. The method measures PCR product accumulation through a FAM-labeled fluorogenic probe (TaqMan). The C(t) (threshold cycle) values obtained from the duck + goose system are used to normalize the ones obtained from the duck-specific system. Analysis of experimental duck/goose foie gras binary mixtures demonstrated the suitability of the assay for the detection and quantitation of duck in the range of 1-25%. This genetic marker can be very useful to avoid mislabeling or fraudulent species substitution of goose by duck in foie gras.

Abstract
To control the spread of bovine spongiform encephalopathy, several DNA methods have been described for the detection of the species origin of meat and bone meal. Most of these methods are based on the amplification of a mitochondrial DNA segment. We have developed a semiquantitative method based on real-time PCR for detection of ruminant DNA, targeting an 88-bp segment of the ruminant short interspersed nuclear element Bov-A2. This method is specific for ruminants and is able to detect as little as 10 fg of bovine DNA. Autoclaving decreased the amount of detectable DNA, but positive signals were observed in feeding stuff containing 10% bovine material if this had not been rendered in accordance with the regulations, i.e., heated at 134 degrees C for 3 instead of 20 min.

Abstract
The European Community ban on use of meat and bone meal in ruminant feed, as a consequence of the spread of bovine spongiform encephalopathy in Europe, has prompted a number of investigations about the possibility of detecting animal tissues in feedstuff. In this paper, a study on vertebrate primers, designed in the 16S rRNA gene of mitochondrial DNA, is described. These primers were able to amplify fragments that contained between 234 and 265 bp. The fragments were specific for bovine, porcine, goat, sheep, horse, rabbit, chicken, trout, and European pilchard and were confirmed by sequence analysis amplicons. The primers were used in a PCR assay applied to five samples of meat and blood meals of different species and subjected to severe rendering treatments (134.4 to 141.9 degrees C and 3.03 to 4.03 bar for 24 min). The presence of vertebrate tissues was detected in all samples. The assay proved to be rapid and sensitive (detection limit 0.0625%). It can be used as a routine method to detect animal-derived ingredients in animal feedstuff.
