Hygienic-sanitary working practices and implementation of a Hazard Analysis and Critical Control Point (HACCP) plan in lobster processing industries

This study aimed to verify the hygienic-sanitary working practices and to create and implement a Hazard Analysis Critical Control Point (HACCP) in two lobster processing industries in Pernambuco State, Brazil. The industries studied process frozen whole lobsters, frozen whole cooked lobsters, and frozen lobster tails for exportation. The application of the hygienic-sanitary checklist in the industries analyzed achieved conformity rates over 96% to the aspects evaluated. The use of the Hazard Analysis Critical Control Point (HACCP) plan resulted in the detection of two critical control points (CCPs) including the receiving and classification steps in the processing of frozen lobster and frozen lobster tails, and an additional critical control point (CCP) was detected during the cooking step of processing of the whole frozen cooked lobster. The proper implementation of the Hazard Analysis Critical Control Point (HACCP) plan in the lobster processing industries studied proved to be the safest and most cost-effective method to monitor each critical control point (CCP) hazards.

APPLICATION of THE HAZARD ANALYSIS and CRITICAL CONTROL POINT (HACCP) SYSTEM on THE MUSHROOM PROCESSING LINE FOR FRESH CONSUMPTION

The Hazard Analysis and Critical Control Point (HACCP) is a preventive system that intends to guarantee the safety and harmlessness of food. It improves the quality of products as it eliminates possible defects during the process, and saves costs by practically eliminating final product inspection. This work describes the typical hazards encountered on the mushroom processing line for fresh consumption. Throughout the process, only the reception stage of mushrooms has been considered a critical control point (CCP). The main hazards at this stage were: the presence of unauthorised phytosanitary products; larger doses of such products than those permitted; the presence of pathogenic bacteria or thermo-stable enterotoxins. Putting into practice such knowledge would provide any industry that processes mushrooms for fresh consumption with a self-control HACCP-based system for its own productions.

Retail Food Establishments: Guide to HACCP Plans

A Hazard Analysis and Critical Control Point (HACCP) system is a plan to reduce the risk of safety hazards in food. The HACCP System identifies potential biological, chemical and physical hazards from the time the food enters the facility to when it is served. The Hazard Analysis identifies critical control points based on the ingredients, raw materials and processes. Control measures are then identified, implemented and monitored to ensure the ongoing safety of the finished products.

Microbiological indicators for the assessment of performance in the hazard analysis and critical control points (HACCP) system in meat lasagna production

The HACCP system is being increasingly used to ensure food safety. This study investigated the validation of the control measures technique in order to establish performance indicators of this HACCP system in the manufacturing process of Lasagna Bolognese (meat lasagna). Samples were collected along the manufacturing process as a whole, before and after the CCPs. The following microorganism s indicator (MIs) was assessed: total mesophile and faecal coliform counts. The same MIs were analyzed in the final product, as well as, the microbiological standards required by the current legislation. A significant reduction in the total mesophile count was observed after cooking (p < 0.001). After storage, there was a numerical, however non-significant change in the MI count. Faecal coliform counts were also significantly reduced (p < 0.001) after cooking. We were able to demonstrate that the HACCP system allowed us to meet the standards set by both, the company and the Brazilian regulations, proved by the reduction in the established indicators

Elaboració d'un manual d'implantació del sistema APPCC per a microcerveseries

L’objectiu del treball ha estat elaborar un manual d’implantació del sistema d'Anàlisi de Perills i Punts Crítics de Control (APPCC) que serveixi de guia a les microcerveseries. En la primera part del manual s’ha realitzat una introducció on s’expliquen els orígens del sistema i es defineix l’APPCC com un sistema que permet identificar, avaluar i controlar els perills significatius en totes les fases de producció, transformació i distribució amb l’objectiu de garantir la innocuïtat dels aliments. Seguidament, s’ha mostrat la importància del Codex Alimentarius, on es troben descrites les directives per a l’aplicació del sistema d’APPCC. També s’ha indicat que el Reglament CE 852/2004, relatiu a la higiene dels productes alimentaris, obliga a les empreses alimentaries a crear, implementar i mantenir procediments permanents basats en els principis del sistema d’APPCC. Posteriorment, s’han exposat els aspectes que cal considerar per a poder implantar un sistema d’APPCC en una microcerveseria. S’han descrit aspectes com el marc legal del sector cerveser, la flexibilitat en l’aplicació del sistema d’autocontrol en les microempreses i els prerequisits. En l’annex 1, s’han desenvolupat els prerequisits necessaris per a les microcerveseries, i en l’annex 2, s’han mostrat exemples de registres derivats de la seva aplicació. Els prerequisits són bàsics per assegurar un entorn i unes condicions de treball higièniques, reduint o eliminant perills de contaminació en els aliments. Els prerequisits consideren els perills generals de l’entorn de treball. En canvi, l’APPCC considera els perills específics del procés de producció. Tot seguit, s’han definit els principis bàsics i les directrius per a l’aplicació del sistema d’APPCC descrits en el Codex Alimentarius, explicant les diferents fases que cal seguir per a la correcta implantació del sistema d’autocontrol. En la segona part del manual, s’ha desenvolupat el sistema d’APPCC per al procés d’elaboració de la cervesa artesana

Elaboración e implantación de un sistema APPCC para industrias elaboradoras de creps

Debido a la coyuntura actual y a la liberalización del comercio de alimentos, es necesariogarantizar la seguridad e inocuidad de los alimentos, las cuales se conseguirán aplicando lasprácticas y las normas apropiadas en materia de seguridad alimentaria. Los reglamentoscomunitarios en materia de seguridad alimentaria, y en particular el Reglamento (CE) nº852/2004 relativo a la higiene de los alimentos, obligan a las empresas alimentarias a aplicarun sistema de autocontrol basado en los principios del Análisis de Peligros y Puntos Críticosde Control (APPCC). En España, la legislación nacional ya contemplaba este requisito. En elámbito de las comidas preparadas, esta exigencia se recogía expresamente en el Real Decreto3484/200, de 29 de diciembre, por el que se establecen las normas de higiene para laelaboración, distribución y comercio de comidas preparadas.En el presente Proyecto/Trabajo Final de Carrera (PTFC), se ha elaborado un manual, queconsta de ocho capítulos, unos anexos y una memoria descriptiva, que servirá de guía para eldiseño de un sistema de APPCC, siguiendo los procedimientos definidos en el CodexAlimentarius, que permita su aplicación a las industrias elaboradoras de creps y a la vezproporcione las pautas necesarias para su implantación. Debido a la imposibilidad de aplicarel sistema de APPCC desarrollado a una industria concreta, se ha elaborado un manualgenérico que cada industria deberá adaptar a sus sistema productivo

Occurrence and Genetic Characteristics of Third-Generation Cephalosporin-Resistant Escherichia coli in Swiss Retail Meat

Prevalence and genetic relatedness were determined for third-generation cephalosporin-resistant Escherichia coli (3GC-R-Ec) detected in Swiss beef, veal, pork, and poultry retail meat. Samples from meat-packing plants (MPPs) processing 70% of the slaughtered animals in Switzerland were purchased at different intervals between April and June 2013 and analyzed. Sixty-nine 3GC-R-Ec isolates were obtained and characterized by microarray, PCR/DNA sequencing, Multi Locus Sequence Typing (MLST), and plasmid replicon typing. Plasmids of selected strains were transformed by electroporation into E. coli TOP10 cells and analyzed by plasmid MLST. The prevalence of 3GC-R-Ec was 73.3% in chicken and 2% in beef meat. No 3GC-R-Ec were found in pork and veal. Overall, the blaCTX-M-1 (79.4%), blaCMY-2 (17.6%), blaCMY-4 (1.5%), and blaSHV-12 (1.5%) β-lactamase genes were detected, as well as other genes conferring resistance to chloramphenicol (cmlA1-like), sulfonamides (sul), tetracycline (tet), and trimethoprim (dfrA). The 3GC-R-Ec from chicken meat often harbored virulence genes associated with avian pathogens. Plasmid incompatibility (Inc) groups IncI1, IncFIB, IncFII, and IncB/O were the most frequent. A high rate of clonality (e.g., ST1304, ST38, and ST93) among isolates from the same MPPs suggests that strains persist at the plant and spread to meat at the carcass-processing stage. Additionally, the presence of the blaCTX-M-1 gene on an IncI1 plasmid sequence type 3 (IncI1/pST3) in genetically diverse strains indicates interstrain spread of an epidemic plasmid. The blaCMY-2 and blaCMY-4 genes were located on IncB/O plasmids. This study represents the first comprehensive assessment of 3GC-R-Ec in meat in Switzerland. It demonstrates the need for monitoring contaminants and for the adaptation of the Hazard Analysis and Critical Control Point concept to avoid the spread of multidrug-resistant bacteria through the food chain.

Estudo comparativo de implementação do sistema HACCP em talhos no Distrito de Setúbal

A carne é um género alimentício com um grande impacte na dieta e nutrição das populações. Porém a carne e os respetivos produtos derivados podem constituir um risco significativo para a saúde do consumidor, caso ocorra uma contaminação microbiológica ou uma alteração decorrente da ação de agentes físicos ou químicos. Assim, torna-se necessário que os locais de venda destes géneros alimentícios cumpram uma série de requisitos, exigidos pela legislação portuguesa e comunitária. Neste enquadramento, o Sistema HACCP (Hazard Analysis and Critical Control Point) surge como uma ferramenta útil e eficaz para prevenção, identificação dos perigos em todas as fases de processamento / produção, e para aplicação de medidas de controlo, podendo assim assegurar-se um elevado nível de segurança e qualidade do produto final. Neste estudo pretende-se caracterizar e comparar as condições de Segurança e Higiene Alimentar de 7 locais de venda de carne e seus produtos no distrito de Setúbal, com o Sistema HACCP já implementado. A colheita de dados foi efetuada a partir de uma lista de verificação, procedendo-se, subsequentemente, a uma análise descritiva dos resultados obtidos. Constatou-se que os talhos apresentam um grau de risco médio. O maior grau de inconformidades detetadas centrou-se nos Domínios: 3 – Condições de Exposição e Venda de Carne; 4 – Preparação e Venda de Carne Picada e Preparados de Carne; 9 – Instalações Sanitárias e Vestiários; 12 – HACCP e Registos. Concluiu-se que subsistem falhas estruturais nas instalações, nos equipamentos e nos utensílios, que comprometem o nível de salubridade do local de venda, porém adicionalmente também se verificou que um dos maiores obstáculos era o próprio manipulador que tende a não cumprir com o código de boas práticas. Neste contexto, aponta-se para a importância da formação / sensibilização no âmbito de Segurança e Higiene Alimentar.
