RESUMO
In developing countries, interest in guinea pig farming is growing exponentially because it provides a regular source of high quality animal protein for domestic consumption. Guinea pigs (Cavia porcellus) are prolific animals, grow and are capable of reproduction on a flexible diet, and are adaptable to a wide range of climates. This article mainly reviews findings on guinea pig meat production, including factors affecting raising guinea pigs, carcass and meat quality. We also present some studies that describe biological and pathologic effects on carcass component composition. During the last decades no standard procedure has been established for guinea pig carcass evaluation, which makes very difficult any comparison of results with other studies around the world. Herein we highlight a variety of factors that significantly affect carcass and meat quality. Some of these factors are production systems, environmental and genetic factors, management systems, the diet and health status, age, sex and reproductive management.

The Food and Drug Administration publishes the Food Code to guide restaurant inspections. The most recent version proposes a three-tier system categorizing violations as priority, priority foundation, and core. This study used a scenario-based questionnaire to examine inspector perceptions and preferences for inspection formats. Results suggest that inspectors would be able to maintain consistent evaluations when changing to the three-tier system, although the classifying terms under the three-tier system were confusing. Additionally, inspectors were not very positive about the new system; they were concerned that the new system would not be easy to understand and use, inspections would take a longer time, it would not accurately reflect the amount of risk associated with violations, and it would not be easy for consumers and managers to understand and use. The results suggest the need for additional training for inspectors before adoption, especially on the rationale and benefits of changing to a three-tier system.

Slaughter by Jewish religious rite is the killing of an animal by cutting the trachea and oesophagus and major blood vessels using a very sharp blade. This operation is subject to strict rules laid down by religious authorities that characterize its sacredness. The aim of the study was to evaluate the specific criteria inherent in the Jewish religious rite, by analysing reject rates during the different phases. In this study, 52.4% of the carcasses failed to quality as Kosher, with 22.9% being rejected due to pulmonary lesions and only 3% for miscuts. The study also revealed legal vacuums in the field of labelling rules.

Informed by quality theory, this systematic literature review seeks to determine the relative importance of beef quality attributes from a consumer perspective, considering search, experience and credence quality attributes. While little change is anticipated in consumer ranking of search and experience attributes in the future, movement is expected in terms of ranking within the credence category and also in terms of the ranking of credence attributes overall. This highlights an opportunity for quality assurance schemes (QAS) to become more consumer focused through including a wider range of credence attributes. To capitalise on this opportunity, the meat industry should actively anticipate new relevant credence attributes and researchers need to develop new or better methods to measure them. This review attempts to identify the most relevant quality attributes in beef that may be considered in future iterations of QAS, to increase consumer satisfaction and, potentially, to increase returns to industry.

The use of ultrasounds has recently gained significant interest in the food industry mainly due to the new trends of consumers toward functional foods. Offering several advantages, this form of energy can be applied for the improvement of qualitative characteristics of high-quality foods as well as for assuring safety of a vast variety of foodstuffs, and at the same time minimizing any negative effects of the sensory characteristics of foods. Furthermore, the non-destructive nature of this technology offers several opportunities for the compositional analysis of foods. However, further research is required for the improvement of related techniques and the reduction of application costs in order to render this technology efficient for industrial use. This review paper covers the main applications of ultrasounds as well as several advantages of the use of the technology in combination with conventional techniques. The effects of ultrasounds on the characteristics, microbial safety, and quality of several foods are also detailed.

The most commonly used technique to prepare samples for the analysis of wine volatile is the headspace solid-phase microextraction (HS-SPME). This method has gained popularity in last few years, as it is a unique solventless preparation technique. In this paper, a summary of recently published studies using HS-SPME for the analysis of wine aromas, with special emphasis on the method developed, has been compiled. Several papers are discussed in detail, mainly with respect to the SPME conditions used. A brief summary of the reviews related to HS-SPME analysis is given and discussed. Several parameters affecting the HS-SPME, such as the salt concentration and the agitation conditions, are used in the same way as used in several papers. The HS-SPME extraction proved to be sufficiently sensitive to satisfy legislative requirements related to low detection and quantification limits as well as method accuracy and precision requirements. However, in order to achieve the best performance and precision, the protocol needs to be optimized for each case. The effect of different parameters must be well characterized to ensure correct extraction and desorption to ensure the transfer of extracted compounds into the analytical system. The operating parameters, such as time, temperature, and agitation, must then be kept constant for all the samples.

Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large amount of solvent, extended operation time/procedure steps, potential sources of error, and high cost. Moreover, SPE can be plied to the samples combined with other analytical methods and sample preparation techniques optionally. SPE technique is a useful tool for many purposes through its versatility. Isolation, concentration, purification and clean-up are the main approaches in the practices of this method. Food structures represent a complicated matrix and can be formed into different physical stages, such as solid, viscous or liquid. Therefore, sample preparation step particularly has an important role for the determination of specific compounds in foods. SPE offers many opportunities not only for analysis of a large diversity of food samples but also for optimization and advances. This review aims to provide a comprehensive overview on basic principles of SPE and its applications for many analytes in food matrix.

With consumer concerns increasing over food quality and safety, the food industry has begun to pay much more attention to the development of rapid and reliable food-evaluation systems over the years. As a result, there is a great need for manufacturers and retailers to operate effective real-time assessments for food quality and safety during food production and processing. Computer vision, comprising a nondestructive assessment approach, has the aptitude to estimate the characteristics of food products with its advantages of fast speed, ease of use, and minimal sample preparation. Specifically, computer vision systems are feasible for classifying food products into specific grades, detecting defects, and estimating properties such as color, shape, size, surface defects, and contamination. Therefore, in order to track the latest research developments of this technology in the agri-food industry, this review aims to present the fundamentals and instrumentation of computer vision systems with details of applications in quality assessment of agri-food products from 2007 to 2013 and also discuss its future trends in combination with spectroscopy.

Fusarium contamination is considered a major agricultural problem, which could not only significantly reduce yield and quality of agricultural products, but produce mycotoxins that are virulence factors responsible for many diseases of humans and farm animals. One strategy to identify toxigenic Fusarium species is the use of modern molecular methods, which include the analysis of DNA target regions for differentiation of the Fusarium species, particularly the mycotoxin-producing Fusarium species such as F. verticillioides and F. graminearum. Additionally, polymerase chain reaction assays are used to determine the genes involved in the biosynthesis of the toxins in order to facilitate a qualitative and quantitative detection of Fusarium-producing mycotoxins. Also, it is worth mentioning that some factors that modulate the biosynthesis of mycotoxins are not only determined by their biosynthetic gene clusters, but also by environmental conditions. Therefore, all of the aforementioned factors which may affect the molecular diagnosis of mycotoxins will be reviewed and discussed in this paper.

Objetivo. Determinar la demanda y el tipo de dietas especiales para alumnos con alergias o intolerancias alimentarias (AIA) en los comedores escolares de Barcelona durante el curso 2011-12, y conocer la implementación de autocontroles y medidas preventivas para la gestión de alérgenos, así como la relación entre la aplicación de estas medidas con diversas variables. Métodos. Estudio descriptivo de una muestra representativa de escuelas (n = 129). Las variables dependientes recogieron información sobre los datos poblacionales de los centros y el alumnado, la demanda de menús especiales y la implementación de medidas preventivas. Las variables independientes fueron la gestión del comedor, el número de comensales y los autocontroles para la gestión de alérgenos. Para las escuelas que elaboraban comidas (n = 92) se calculó un índice a partir de las preguntas de medidas preventivas. Mediante prueba t de Student se compararon las medias de los índices, estratificando según las variables independientes. Resultados. El 89% de las escuelas sirvieron dietas AIA (1507 dietas AIA/día, el 5% del total de los menús) y el 65% no disponían de un plan de control de alérgenos. La media de los índices fue de 11,6 sobre 17. Los comedores gestionados externamente, con más comensales y que disponían de autocontroles, implementaron más medidas preventivas de gestión de alérgenos (p < 0,05). Conclusiones. Un alto porcentaje de centros manifiestan llevar a cabo medidas preventivas en el proceso de elaboración y servicio de menús especiales. Desde los servicios de inspección sanitaria es necesario promover la implementación de un plan de control de alérgenos en los comedores escolares para gestionar este riesgo alimentario (AU)
Objective. To determine demand for special meals and their types for students with food allergies or intolerances (FAI) in school canteens in Barcelona (Spain) during the 2011-12 school year, and to ascertain the degree of implementation of self-assessment plans and preventive measures for the management of allergens, and the relationships between the application of such measures and other variables. Methods. A descriptive study was performed of a representative sample of schools (n = 129). The dependent variables collected data on the schools and students, the level of demand for special meals, and the implementation of preventive measures. Independent variables consisted of canteen management, the number of users, and whether self-assessment plans were implemented. For those schools that prepared meals (n = 92), an index was calculated from the questions on preventive measures. Student t-tests were used to compare the means of the indices with stratification by the independent variables. Results. A total of 89% of schools served special meals for students with FAI (1,507 special meals per day, 5% of all meals) and 65% had no allergen control plan. The mean of the indices was 11.6 out of 17. Externally managed canteens, with more users and with self-assessment plans, implemented more preventive measures for allergen management (p < 0.05). Conclusions. A high proportion of schools report carrying out preventive measures in the process of preparing and serving special meals. Those with self-assessment plans have better preventive practices. To manage this food-related risk, food hygiene inspection services should promote the implementation of allergen control plans in school canteens (AU)

Despite having a low occurrence rate, Listeria monocytogenes is one of the most prominent foodborne pathogens in Australia. The organism is responsible for severe outbreaks with high case fatality and substantial economic losses due to food recalls. In this study, we analyze the incidence trends of listeriosis in Australia during 2001-2010, discuss the relevance of food recalls, and investigate the pathogen's role in foodborne outbreaks. A significant epidemiological finding was a consistently high national age-specific rate recorded for individuals aged 60 years and over. Analysis of Australian Listeria outbreak and food recall data suggests deficiencies in food safety programs of food manufacturing businesses implicated in Listeria outbreaks and revealed that ready-to-eat foods are high-risk vehicles for transmitting listeriosis. Highlighted is Australia's highly efficient Listeria management and surveillance systems bolstered by the introduction of Listeria molecular subtyping in 2010 coupled with a nationally standardized questionnaire by the "Australian foodborne disease surveillance network (OzFoodNet)." The detection of clusters and therefore outbreaks was now possible, allowing cases to be linked across multiple jurisdictions and enabling timely public health action. Considering current changes in food production and consumption patterns, continuous monitoring and improvement of surveillance systems will provide ongoing public health benefits and be crucial to future development of food safety policy for Australia.

Although several meta-analysis studies have been published comparing the quality of food derived from organic and non-organic origin, it is still not clear if food from organic production per se can guarantee product-related added value to consumers. This paper aims to summarize the status quo in order to identify research gaps and suggest future research challenges. Organic food is described according to a quality model already published. The influence of organic production on food quality is structured in primary production and processing. Furthermore, organic food authentication is discussed. Organic food seems to contain fewer pesticide residues and statistically more selected health-related compounds such as polyphenols in plant products and polyunsaturated fatty acids in milk and meat products, but the health relevance for consumers is not clear yet. Comparing food from organic origin with so called 'conventional' food seems not to be appropriate, because 'conventional' is not defined. In organic food quality research a system approach is needed from which systemic markers can be selected. Research on the impact of processing technologies on the quality according to organic principles seems of high relevance, since most of the food is processed.

Organic food quality determination needs multi-dimensional evaluation tools. The main focus is on the authentication as an analytical verification of the certification process. New fingerprinting approaches such as ultra-performance liquid chromatography-mass spectrometry, gas chromatography-mass spectrometry, direct analysis in real time-high-resolution mass spectrometry as well as crystallization with and without the presence of additives seem to be promising methods in terms of time of analysis and detecting organic system-related parameters. For further methodological development, a system approach is recommended, which also takes into account food structure aspects. Furthermore, the authentication of processed organic samples needs more consciousness, hence most of organic food is complex and processed.

Food allergy represents an important food safety issue because of the potential lethal effects; the only effective treatment is the complete removal of the allergen involved from the diet. However, due to the growing complexity of food formulations and food processing, foods may be unintentionally contaminated via allergen-containing ingredients or cross-contamination. This affects not only consumers' well-being but also food producers and competent authorities involved in inspecting and auditing food companies. To address these issues, the food industry and control agencies rely on available analytical methods to quantify the amount of a particular allergic commodity in a food and thus to decide upon its safety. However, no "gold standard methods" exist for the quantitative detection of food allergens. Nowadays mostly receptor-based methods and in particular commercial kits are used in routine analysis. However, upon evaluation of their performances, commercial assays proved often to be unreliable in processed foods, attributed to the chemical changes in proteins that affect the molecular recognition with the receptor used. Unfortunately, the analytical outcome of other methods, among which are chromatographic combined with mass spectrometric techniques as well as DNA-based methods, seem to be affected in a comparable way by food processing. Several strategies can be employed to improve the quantitative analysis of allergens in foods. Nevertheless, issues related to extractability and matrix effects remain a permanent challenge. In view of the presented results, it is clear that the food industry needs to continue to make extra efforts to provide accurate labeling and to reduce the contamination with allergens to an acceptable level through the use of allergen risk management on a company level, which needs to be supported inevitably by a tailor-validated extraction and detection method.
