Pig Carcasses

An investigation was carried out in a pig abattoir to determine the microbiological status of carcasses being produced after slaughter and dressing. The carcasses were sampled in accordance with EC Decision 471 in relation to the application of hazard analysis critical control point (HACCP) criteria to the slaughter of animals. In this regard, four sites on the animals were examined on five consecutive carcasses during each of 10 visits for the presence of total viable counts and Enterobacteriaceae. A comparison of the EC four-site method, with a whole-body swab technique, as a means of measuring carcass contamination found that the two methods gave significantly different results for both groups of organisms. A comparison of the mean of the individual data from the four sites with the data from the pooled samples revealed that there was a poor relationship between the two. Samples may be taken by excision or swabbing and allocated to three categories of process control, which, in turn, are based on microbiological criteria that are different, depending on whether sampling is by excision or swabbing. The influence of these changes in microbiological criteria is discussed in relation to the categorization of samples as acceptable, marginal, or unacceptable and the influence this has on process control. Finally, the proposed introduction of Salmonella as a safety indicator in the EC HACCP system is discussed.

Pig Carcasses

At sequential steps of slaughter (scalding, dehairing, singeing, polishing, trimming, washing, and chilling), 200 pig carcasses from two abattoirs were examined for total viable bacteria count (TVC) and the presence of Enterobacteriaceae and coagulase-positive Staphylococcus (CPS) by the wet-dry double-swab technique at the neck, belly, back, and ham. Before scalding, mean TVCs ranged from 5.0 to 6.0 log CFU cm32, and Enterobacteriaceae and CPS were detected on all carcasses. At abattoir A, mean TVCs and the percentage of Enterobacteriaceae-positive carcasses were reduced (P < 0.05) after scalding (1.9 log CFU cm−2 and 12%, respectively), singeing (1.9 log CFU cm−2 and 66%, respectively), and blast chilling (2.3 log CFU cm−2 and 17%, respectively) and increased (P < 0.05) after dehairing (3.4 log CFU cm−2 and 100%, respectively) and polishing (2.9 log CFU cm−2). The proportion of CPS-positive samples decreased to ≤10% after scalding and remained at this level. At abattoir B, mean TVCs and the percentages of Enterobacteriaceae- and CPS-positive carcasses were reduced (P < 0.05) after scalding (2.4 log CFU cm−2 and 29 and 20%, respectively), polishing (3.7 log CFU cm−2), and chilling (2.6 log CFU cm−2 and 55 and 77%, respectively) and increased (P < 0.05) after the combined dehairing-singeing (4.7 log CFU cm−2 and 97 and 100%, respectively). Among sites, the neck tended to yield higher levels of contamination from trimming to chilling at both abattoirs (P < 0.05). Consequently, scalding, singeing, and chilling may be integrated in a hazard analysis critical control point (HACCP) system for pig slaughter. As indicated by the higher levels of contamination on carcasses after dehairing-singeing and the following stages at abattoir B, each abattoir should develop its own baseline data and should customize HACCP systems to match process- and site-specific circumstances.

Standardized inspections of food premises are part of environmental health systems implemented worldwide. The food safety strategy for the 2004 Olympic Games included standardized inspections to ensure uniformity and consistency of procedures and effective electronic management of data. Inspections were carried out by 196 inspectors in the five Olympic cities: Athens, Thessalonica, Volos, Iraklio, and Patra. From January 2003 to September 2004, a total of 1,249 food premises were inspected. An unsatisfactory inspection result (C grade) was received by 347 (27.8%) food premises, a relatively satisfactory result (B grade) was received by 332 (26.6%), and a satisfactory result (A grade) was received by 570 (45.6%). About 16% of inspected premises did not hold a valid permit. Unsatisfactory inspection results were more frequent for premises located in the two largest Greek cities in comparison with the other smaller cities (relative risk = 1.95, 95% confidence interval [CI] = 1.36 to 2.80). Based on logistic regression analysis, unsatisfactory inspection results were positively associated with food premises that were not located on a ground floor (odds ratio [OR] = 2.56, 95% CI = 1.39 to 4.73) and negatively associated with application of hazard analysis critical control point (HACCP) principles (OR = 0.27, 95% CI = 0.10 to 0.71). Food hygiene education through formal training programs should be encouraged to improve compliance of food premises. Food premises located on hotel floors and serving buffet meals are at higher risk for unsatisfactory conditions. Businesses that implemented a HACCP system within their operations to ensure food safety operated under more hygienic conditions. Future inspections by Public Health Authorities should involve elements of audit after the legislation for the application of HACCP principles.

ResumenLa variabilidad de los alimentos tradicionales producidos de manera artesanal es admisible, pero su inocuidad debe garantizarse. La ejecución de Buenas Prácticas de Manufactura (BPM) es fundamental para la construcción de sistemas de gestión de la inocuidad como el Análisis de Riesgos y Puntos Críticos de Control (HACCP) e ISO-22000-Food Safety Management System. El cumplimiento de este tipo de prácticas en la producción de alimentos tradicionales en México es escaso. Tomando al queso de Poro, como ejemplo de este tipo de alimentos, el presente documento describe las condiciones y controles de su proceso de producción. Ello como el primer paso para documentar la factibilidad de implementar sistemas de gestión de la inocuidad. Esto es dado que la legislación en México permite la comercialización de este tipo de quesos si su producción cumple con controles basados en BPM.AbstractThe variability of hand-made traditional food products is admissible, but food safety must be guaranteed. The accomplishment of Good Manufacturing Practices (GMP) is essential to implement food safety management systems as the Hazard Analysis and Critical Control Point (HACCP) system and the ISO-22000-Food Safety Management System. The fulfillment of these practices in the manufacture of traditional food products in Mexico is limited so, taking Poro cheese as an example of this kind of food products, the present document is intended to describe Poro cheese’s production controls and conditions as the first step to evaluate the feasibility to implement a food safety management system, since Mexico’s regulation allows the commercialization of these kind of cheeses if their production process complies with GMP.

Mycotoxins, as secondary metabolic products of molds, are common contaminants of raw feed materials and compound feeds. Depending on the agro-meteorological and storage conditions, molds can contaminate grains and produce mycotoxins in the field, before and after harvest and during storage. Way of preventing animal mycotoxicoses and transfer of mycotoxins to humans through food chain is regular inspection on mycotoxicological feed safety. This paper presents the results of examination of aflatoxin, ochratoxin and zearalenone in 89 samples tested under laboratory conditions during a one year period. The analyses of types of samples, contamination, and their origin demonstrated the need for preventive control of mycotoxin content, primarily in grains. The results of testing the content of aflatoxin in milk indicate the existence of risks to human health. In order to protect humans and animals from mycotoxicological contamination, we propose the use of the system hazard analysis and critical control point (HACCP), which has been proved to be an effective strategy in food safety control. The basic principles of HACCP approach in the production of feed and foodstuffs, as well as the compliance and harmonization of legislations with those in the European Union, in the field of mycotoxicological tests, are the best prevention against mycotoxin effects on health and economy. Implementation of HACCP system currently presents one of the basic preconditions for the export of our products and their placement on the European market.

The aim of this study was to model the growth kinetics of Listeria monocytogenes on ready-to-eat ham and sausage at different temperatures (4 to 35°C). The observed data fitted well with four primary models (Baranyi, modified Gompertz, logistic, and Huang) with high coefficients of determination (R2 > 0.98) at all measured temperatures. After the mean square error (0.009 to 0.051), bias factors (0.99 to 1.06), and accuracy factors (1.01 to 1.09) were obtained in all models, the square root and the natural logarithm model were employed to describe the relation between temperature and specific growth rate (SGR) and lag time (LT) derived from the primary models. These models were validated against the independent data observed from additional experiments using the acceptable prediction zone method and the proportion of the standard error of prediction. All secondary models based on each of the four primary models were acceptable to describe the growth of the pathogen in the two samples. The validation results indicate that the optimal primary model for estimating the SGR was the Baranyi model, and the optimal primary model for estimating LT was the logistic model in ready-to-eat (RTE) ham. The Baranyi model was also the optimal model to estimate the SGR and LT in RTE sausage. These results could be used to standardize predictive models, which are commonly used to identify critical control points in hazard analysis and critical control point systems or for the quantitative microbial risk assessment to improve the food safety of RTE meat products.
