Standards for the hand hygiene of food handlers / Sanette KlingenbergKlingenberg, Sanette January 2008 (has links)
Globally, investigations into food-borne illnesses show that the majority of cases involve poor hand hygiene of the food handler. The challenge of providing safe food therefore requires new strategies for evaluating cross-contamination of pathogenic micro-organisms on the food handler's hands, which might be detrimental or hazardous to the health of the patient Although food-borne diseases may be multifactorial in aetiology, no standards or evaluation systems, such as an occupational health surveillance programme, are available to monitor and ensure that food is free of pathogens. The formulation and implementation of standards may contribute to ensuring that food handlers comply with hand hygiene practices during food handling. Such practices guarantee that food reaching the patient is safe.
The objectives in this research project originated from the occupational health practice and gave direction of the empirical research project. The literature was reviewed to discover what is currently known concerning the food handlers' hand hygiene during food handling and food-borne illnesses and the theoretical framework gave direction and guidance to the survey design of the empirical research, which was quantitative, explorative, descriptive and contextual in nature. The food handlers from the food preparation sections of the four major healthcare services in Potchefstroom, in the North West Province, South Africa, were the target population and the sampling method was all-inclusive (n=110). Eighty (75.47%) food handlers participated in the research project.
The design entailed three steps. The first was conducted with a questionnaire, to identify the food handlers' compliance with hand hygiene during food handling. The second step involved determining the prevalence of Escherichia coli and Staphylococcus aureus on the food handlers' hands. The results were used for the formulation of standards for the hand hygiene of food handlers.
Finally, recommendations for practice, education and research were made. The implementation of these recommendations could contribute knowledge to the body of nursing and promote good hand hygiene practices in the healthcare service. / Thesis (M.Cur.)--North-West University, Potchefstroom Campus, 2009.

Inledning: Salladsbarer är ett trendigt och lättillgängligt måltidsalternativ som finns i de flesta dagligvaruhandelsbutiker. Personal och konsumenter hanterar dagligen livsmedel och utrustning vid salladsbaren. Det saknas idag information och kunskap om hur personers beteende kring en salladsbar kan påverka livsmedelssäkerheten. Syfte: Undersöka risker med offentlig livsmedelshantering vid en salladsbar. Metod: Dolda observationer av personal och konsumenters riskbeteende. Hygienkontroll av portionsförpackningar. Bakterieprovtagningar av ytor i anknytning till salladsbaren följt av en artbestämning. Studiens intention är att ge en kvalitativ bild av de hygienutmaningar som livsmedelshantering i en offentlig miljö kan innebära. Resultat/Slutsats: Resultatet av observationerna visar att det sker ett flertal olika riskbeteende i anknytning till salladsbaren, framför allt bland konsumenter, vilket kan leda till korskontamination. Hygienkontrollen visade att medelvärdet av samtliga portionsförpackningar låg inom gränsvärdet för godkänd hygienstandard. Analysen av bakterieprover tagna från olika ytor kopplade till salladsbaren visade att det förekommer en hög variation av olika bakterier. Det finns en risk för bakteriespridning genom personers riskbeteende kopplade till salladsbaren. Risker kan förebyggas genom ökad kunskap och information om hygien och normer för beteende kring salladsbarer. / Introduction: Salad bars are a trendy and easily accessible meal option available in most grocery stores. Staff and consumers handle food and equipment at the salad bar daily. There is today no information and knowledge about how people's behavior around a salad bar can affect food safety. Purpose: To investigate risks with public food management at a salad bar. Method: Hidden observations of staff and consumer risk behavior. Hygiene control of portion packages. Bacterial sampling of surfaces associated with the salad bar followed by a species determination. The aim of the study is to provide a qualitative picture of the hygiene challenges that food management in a public environment may imply. Result/Conclusion: The results of the observations show that there are a variety of risk behaviors associated with the salad bar, especially among consumers, which can lead to cross contamination. The hygiene check showed that the average of all portion packages was within the limit of approved hygiene standards. The analysis of bacterial samples taken from different surfaces linked to the salad bar showed that there was a high variety of different bacteria. There is a risk of bacterial spread through people's risk behavior linked to the salad bar. Risks can be prevented through increased knowledge and information on hygiene and norms around salad bars.

Effect of Poor Sanitation Procedures on Cross-Contamination of Animal Species in Ground Meat ProductsChung, Sunjung 28 May 2019 (has links)
While the presence of ≥1% of an undeclared species in ground meat generally used as an indicator of intentional mislabeling as opposed to cross-contamination, the actual percent of undeclared species resulting from cross-contamination has not been experimentally determined. The objective of this study was to quantify the effect of sanitation procedures on the crosscontamination of animal species in ground meat products, using undeclared pork in ground beef. Pork (13.6 kg) was processed using a commercial grinder, then one of three sanitation treatments was completed (“no cleaning”, “partial cleaning”, or “complete cleaning”). Next, beef (13.6 kg) was ground using the same equipment. For “no cleaning,” beef was ground immediately after pork without any cleaning step; for “partial cleaning,” the hopper tray was wiped, and excess meat was taken out from the auger; for “complete cleaning,” all parts of the grinder were disassembled and thoroughly cleaned with water and soap. A 100-g sample was collected for each 0.91 kg (2 lb) of beef processed with the grinder and each sanitation treatment was tested twice. Real-time polymerase chain reaction (PCR) was used to quantify pork in ground beef. For “no cleaning,” the first 100-g sample of ground beef run through the grinder contained 24.42 ± 10.41% pork, while subsequent samples contained

Cross-Contamination Risk of Dental Tray Adhesives: An In Vitro StudyPaczkowski, Isabel, Stingu, Catalina S., Hahnel, Sebastian, Rauch, Angelika, Schierz, Oliver 05 May 2023 (has links)
Background: The aim of this study was to investigate the risk of cross-contamination in dental tray adhesives with reusable brush systems. Methods: Four dental tray adhesives with different disinfectant components were examined for risk as a potential transmission medium for Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus oralis, and Candida albicans. Bacterial and fungal strains were mixed with artificial saliva. The contaminated saliva was intentionally added to tray adhesive liquid samples. At baseline and up to 60 min, 100 microliters of each sample were collected and cultivated aerobically on Columbia and Sabouraud agar for 24 or 48 h, respectively. Results: At baseline, contamination with Staphylococcus aureus and Candida albicans could be identified in three out of four adhesives. In the subsequent samples, low counts of up to 20 colony-forming units per milliliter could be observed for Staphylococcus aureus. All other strains did not form colonies at baseline or subsequently. Adhesives with isopropanol or ethyl acetate as disinfectant additives were most effective in preventing contamination, while adhesives with hydrogen chloride or acetone as a disinfectant additive were the least effective. Conclusion: Within 15 min, the tested adhesives appeared to be sufficiently bactericidal and fungicidal against all microorganisms tested.

Vegetais minimamente processados prontos para o consumo: influência da etapa de desinfecção na inativação de Salmonella Typhimurium, na ocorrência da contaminação cruzada e na avaliação quantitativa de risco microbiológico em relação a este patógeno / Minimally processed ready-to-eat vegetables: influence of washing-disinfection step on Salmonella Typhimurium inactivation, on occurrence of cross-contamination and on quantitative microbiological risk assessment regarding this pathogenMaffei, Daniele Fernanda 29 April 2016 (has links)
Dados mundiais apontam haver uma associação entre o aumento do comércio de vegetais minimamente processados prontos para o consumo (VPC) e o aumento da ocorrência de surtos de enfermidades transmitidas por alimentos. Durante o processamento industrial de VPC, a desinfecção é a principal etapa de inativação de micro-organismos patogênicos presentes, mas nessa etapa também pode ocorrer contaminação cruzada, com transferência de contaminantes de produtos contaminados para não-contaminados. Neste trabalho, foram coletadas informações sobre as práticas empregadas na etapa de desinfecção em dez importantes indústrias produtoras de VPC no Estado de São Paulo, avaliando-se, em seguida, a influência dessas práticas na qualidade microbiológica dos produtos e na inativação de Salmonella Typhimurium, bem como na ocorrência de contaminação cruzada por este patógeno. Um modelo de avaliação quantitativa de risco microbiológico foi elaborado para estimar o impacto da contaminação cruzada durante a etapa de desinfecção no risco de infecção por Salmonella devido ao consumo de VPC. Observou-se que, em todas as indústrias visitadas, a desinfecção dos vegetais era feita com produtos à base de cloro em concentrações de 50 a 240 mg/L, que resultava em redução de até 1,2 log na carga microbiana dos vegetais que entravam na linha de processamento. Ao avaliar a influência das características da água de processamento (pH, temperatura, concentração de matéria orgânica e concentração de dicloroisocianurato de sódio) e do tempo de contato entre a água clorada e os vegetais na redução de Salmonella, observou-se que a concentração do produto à base de cloro foi o parâmetro que apresentou maior influência (p<0.05). Concentrações de dicloroisocianurato de sódio acima de 10 mg/L foram necessárias para controle da contaminação cruzada durante a etapa de lavagem. O modelo de avaliação de risco construído indicou quantitativamente haver uma relação entre a concentração de dicloroisocianurato de sódio na água de desinfecção e o risco de ocorrência de surtos causados por Salmonella em VPC. Cenários simulando uso de dicloroisocianurato de sódio em concentrações abaixo de 5 mg/L indicaram que mais de 96% dos casos preditos de infecção por Salmonella poderiam ser atribuídos à ocorrência de contaminação cruzada, enquanto que em cenários com concentrações acima de 50 mg/L, casos de infecção devidos à contaminação cruzada não foram preditos. Estes resultados mostram que o controle da qualidade da água e o monitoramento da concentração de sanitizante na etapa de desinfecção são essenciais para evitar a ocorrência de contaminação cruzada e garantir a produção de VPC seguros para o consumo. / Surveillance data in several countries show an association between consumption of minimally processed ready-to-eat (RTE) vegetables and increased occurrence of foodborne diseases outbreaks. During RTE vegetables processing, washing-disinfection is the main step aiming to ensure inactivation of pathogenic microorganisms, but also is the step in which cross-contamination may occur, with transfer of contaminants from contaminated to non-contaminated products. In this study, we collected information on the practices employed during the washing-disinfection step in ten RTE vegetables processing plants located in the State of Sao Paulo, Brazil, and evaluated the influence of these washing practices on the microbial quality of the products and inactivation of Salmonella Typhimurium, as well as on the occurrence of cross-contamination by this pathogen. A quantitative microbial risk assessment model was built in order to estimate the impact of cross-contamination during the washing step on the risk of infection by Salmonella due to the consumption of RTE vegetables. In all visited processing plants, the disinfection step was done using chlorine-based products, in concentrations ranging from 50 to 240 mg/L, achieving a reduction of up to 1.2 log in the microbial load of vegetables entering the processing line. When the influence of washing water parameters (pH, temperature, organic load and sodium dichloroisocyanurate concentration) and time of contact between chlorinated water and vegetables on reduction of Salmonella were evaluated, sodium dichloroisocyanurate concentration influenced the most (p<0.05). Concentrations above 10 mg/L were necessary for avoiding cross-contamination during washing step. The risk assessment model indicated quantitatively a relationship between sodium dichloroisocyanurate concentration and the risk of illness caused by Salmonella in RTE vegetables. When simulation was done with less than 5 mg/L of sodium dichloroisocyanurate, most (>96%) of the illnesses arose from cross-contamination. However, when the concentration was 50 mg/L or higher, no illnesses arising from cross-contamination were predicted. These results show that controlling the quality of the water and monitoring the concentration of the sanitizer in the disinfection step are essential to avoid occurrence of cross contamination and ensure production of RTE vegetables that are safe for consumption.

Contaminação cruzada durante o fatiamento de produto cárneo pronto para o consumo: foco em Listeria monocytogenes / Cross contamination during slicing of a ready-to-eat meat product: focus on Listeria monocytogenesFaria, Daniele Bezerra 01 December 2016 (has links)
Surtos e casos de listeriose reportados mundialmente e associados a produtos cárneos processados prontos para consumo podem ter sido causados pela contaminação cruzada com Listeria monocytogenes ocorrida durante a etapa de fatiamento destes produtos no varejo. Considerando o impacto da contaminação cruzada para a saúde pública, este trabalho teve por objetivo estudar a transferência de L. monocytogenes durante a etapa de fatiamento de rosbife do tipo \"caseiro\", simulando, em laboratório, cenários observados em estabelecimentos comerciais em relação às práticas adotadas durante o fatiamento. Objetivou-se também avaliar o papel do nível da contaminação do produto (baixo e alto) causador da contaminação experimental do fatiador na contaminação cruzada resultante, bem como avaliar se a exposição da cepa de L. monocytogenes a um sanitizante em concentração insuficiente para a sua eliminação influencia a contaminação cruzada observada. A contaminação do fatiador foi obtida por meio do fatiamento de peças de rosbife experimentalmente contaminadas com o patógeno por imersão em uma suspensão de L. monocytogenes contendo 8 log UFC/mL (alto nível de contaminação) e 4 log UFC/mL (baixo nível de contaminação). Os experimentos foram realizados até a obtenção de 200 fatias. As enumerações de L. monocytogenes nas fatias obtidas foram feitas empregando-se um método cultura-dependente (ISO 11290-2:1998) e um método qPCR, calculando-se também as taxas de transferência. Os resultados mostraram que a contaminação dos fatiadores resultou na transferência do patógeno até pelo menos a 120ª fatia de uma nova peça de rosbife fatiada posteriormente. Nos experimentos realizados com L. monocytogenes exposta ao sanitizante Oasis Compac 22 Quat em concentração insuficiente para sua eliminação, foi possível enumerar o patógeno até a 200ª fatia de rosbife obtida após a contaminação experimental do fatiador, independentemente do nível de contaminação da peça de rosbife usada para a contaminação do fatiador. Equações matemáticas resultantes, que descrevem os dados experimentais obtidos, apresentaram R2>0,7 e p<0,05, mostrando bom ajuste. Esses resultados ressaltam a importância de medidas para evitar a ocorrência de contaminação cruzada durante a etapa de fatiamento de produtos cárneos prontos para o consumo, bem como da higienização adequada dos equipamentos utilizados, de forma a fornecer produtos seguros para o consumidor. / Outbreaks and cases of listeriosis reported worldwide and associated to ready-to-eat meat products may have been caused by cross contamination with Listeria monocytogenes occurred during the slicing step of these products at retail. Considering the impact of cross-contamination to public health, this study aimed to study the transfer of L. monocytogenes during the slicing step of homemade type roast-beef simulating in the laboratory scenarios seen in commercial establishments. The study also aimed to evaluate the role of product contamination level (low and high) causing the experimental contamination of the slicer in the resulting cross-contamination and to evaluate if the exposure of the L. monocytogenes strain to a sanitizer in insufficient concentration for the elimination influences the observed cross-contamination. Contamination of the slicer was obtained through the slicing of roast-beef pieces experimentally contaminated with the pathogen by immersion in a suspension of L. monocytogenes containing 8 log CFU/ml (high contamination) and 4 log CFU/mL (low contamination). The experiments were carried out to obtain 200 slices. Enumerations of L. monocytogenes in the slices employed a culture-dependent method (ISO 11290-2: 1998) and qPCR method, also calculating transfer rates. The results showed that contamination of slicers resulted in the transfer of the pathogen to at least the 120th slice of a new piece of roast-beef sliced subsequently. In experiments conducted with L. monocytogenes exposed to the sanitizer Oasis Compac 22 Quat in insufficient concentration for its elimination, the pathogen could be enumerated until the 200th slice obtained after the slicer contamination, regardless of the contamination level of the roast beef used for contamination of the slicer. Mathematical equations describing the experimental data presented R2>0.7 and p<0.05, showing good fit. These results underscore the importance of measures to prevent the occurrence of cross contamination during the slicing step of ready-to-eat meat products, as well as the proper cleaning of the equipment used in order to provide safe products to the consumer.

Estimativa da transferência de Salmonella typhimurium DT 177 entre faca de aço inoxidável e carne suína artificialmente contaminadaNavarrete Rivas, Cláudia Andrea January 2017 (has links)
A contaminação cruzada por Salmonella spp. durante o processo de abate de suínos contribui para o aumento da prevalência de carcaças positivas no pré-resfriamento. Um dos fatores que pode contribuir para a contaminação cruzada é a execução de cortes e palpação de carcaças durante o processo de inspeção. O presente estudo teve como objetivo estimar, por meio de ensaios laboratoriais, a transferência de Salmonella Typhimurium DT 177 entre faca e carne suína, para subsidiar análises futuras aplicadas ao processo de abate. Foram conduzidas observações independentes e aleatórias da transferência de uma cepa de S. Typhimurium resistente a Ampicilina (AmpR), entre faca e carne suína, as quais formaram quatro coleções de dados: Coleção de dados A: transferência de S. Typhimurium AmpR de faca contaminada para porção de carne suína cortada uma vez (n=20); Coleção de dados B: transferência de S. Typhimurium AmpR de faca contaminada para porção de carne suína cortada cinco vezes no mesmo lugar (n=20); Coleção de dados C: Transferência de S. Typhimurium AmpR de porção de carne suína contaminada para faca após execução de um corte (n=20); Coleção de dados D: Transferência de S. Typhimurium AmpR de porção de carne suína contaminada para faca após execução de cinco cortes no mesmo lugar (n=20). As bactérias transferidas foram quantificadas na lâmina da faca e na superfície da carne, a porcentagem de transferência foi calculada em todas as coleções de dados. As porcentagens de transferência entre as coleções de dados foram comparadas por meio de teste t para amostras independentes usando o programa R Core Team. As percentagens médias de transferência na coleção de dados A e B foram de 6,26% (4,7% – 7,7%) e 8,32% (6,4% - 10,2%). Nas coleções de dados C e D, as percentagens médias de transferência foram, respectivamente, 0,42% (0,3% - 0,5%) e 0,3% (0,2% - 0,4%). Não houve diferença significativa entre as percentagens de transferência após um e cinco cortes consecutivos. A partir disso, conclui-se que há transferência de S. Typhimurium da faca para a carne suína, bem como da carne suína para a faca. A porcentagem de transferência da carne suína contaminada para a faca é baixa, ao passo que a faca contaminada transfere alta percentagem do total de células de S. Typhimurium que carreia, durante a realização dos cortes. / Cross-contamination by Salmonella spp. during the pig slaughtering process contributes to increase the prevalence of positive carcasses in pre-chilling. One of the factors that may contribute to cross-contamination is the implementation of cuts and palpation of carcasses during the inspection process. The present study aimed to estimate, through laboratory tests, the transfer of Salmonella Typhimurium between knife and swine meat, to support future analyzes applied to the slaughter process. Independent and random observations of the transfer of a strain of S. Typhimurium Ampicillin-resistant (AmpR) between knife and swine meat were conducted, which formed four collections of data: Data collection A: Transfer of S. Typhimurium AmpR from contaminated knife to one portion of swine meat cut once (n = 20); Data collection B: Transfer of S. Typhimurium AmpR from contaminated knife to swine meat portion cut five times in the same place (n=20); Data collection C: Transfer of S. Typhimurium AmpR from portion of contaminated meat swine to knife after a cut (n=20); Data collection D: Transfer of S. Typhimurium AmpR from swine meat portion contaminated to knife after five cuts in the same place (n=20). The transfer percentages between the data collection were compared by t-test for independent samples using the R Core Team software. The mean transfer percentages in the data collection A and B were 6,26% (4,7% - 7,7%) and 8,32% (6,4% - 10,2%). In the C and D data collections, mean transfer rates were, respectively, 0.42% (0.3% - 0.5%) and 0.3% (0.2% - 0.4%). There was not significant difference between transfer rates after one and five consecutive cuts. From this, it is concluded that there is transfer of S. Typhimurium from the knife to the swine meat as well as from the swine meat to the knife. The percentage of transfer of contaminated pork to the knife is low, while the contaminated knife transfers at high percentage of the total number of S. Typhimurium cells it carries during cuts.

Previous issue date: 2016-02-18 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / As doenças transmitidas por alimentos são causadas pela ingestão de alimentos contaminados, sendo que em 2013 os principais agentes causadores destas doenças foram Salmonella spp. e Campylobacter spp. No homem, Campylobacter spp. provoca sintomatologia gastrointestinal, que pode variar de uma forma mais suave até formas mais severas. Suínos podem ser portadores destes micro-organismos e produtos de suínos têm sido implicados em casos e surtos de campilobacteriose em humanos. Logo, o objetivo deste trabalho foi rastrear Campylobacter spp. no fluxograma de abate de suínos para compreender o comportamento destes patógenos na linha de produção. Foi acompanhado um total de 40 suínos oriundos de 10 baias de uma granja no Rio Grande do Sul durante o abate. Amostras de fezes foram coletadas no reto do animal logo após a insensibilização. Amostras da superfície da carcaça foram coletadas após a saída dos animais da depiladeira, após a evisceração, momentos antes da carcaça entrar na câmara de resfriamento e da papada. Amostras da água do tanque de escaldagem foram coletadas antes de iniciar o abate de cada lote e após a passagem dos animais também. Os isolados foram obtidos através de culturas microbiológicas e a identificação das espécies foi realizada pela técnica de PCR. Os perfis de bandas das cepas foram determinados por rep-PCR e comparados entre si. Das 200 amostras coletadas, 19 (9,5%) foram positivas para Campylobacter, sendo todas caracterizadas como C. coli. Destes isolados, sete (36,8%) foram obtidos das amostras do reto, sete (36,8%) da pós-evisceração e cinco (26,3%) antes do ingresso na câmara de resfriamento. Através da análise por rep-PCR, observou-se que os animais, uma vez contaminados por C. coli na granja, podem carrear o micro-organismo durante as etapas do fluxograma de abate e que contaminações cruzadas também têm papel importante na contaminação final da carcaça. O manejo higiênico-sanitário adotado nas boas práticas de fabricação é fundamental no controle da contaminação por C. coli. / The foodborne illnesses are caused by contaminated food, and in 2013 the main causative agents of these diseases were Salmonella spp. and Campylobacter spp. In man, Campylobacter spp. causes gastrointestinal symptoms, which can vary more smoothly even more severe forms. Pigs can be carriers of microorganisms and pork products have been implicated in cases of campylobacteriosis outbreaks in humans. Therefore, the aim of this study was to track Campylobacter spp. in pig slaughtering flowchart to understand the behavior of these pathogens in the production line. A total of 40 pigs originating from 10 bays a farm in Rio Grande do Sul was accompanied during slaughter. Stool samples were collected in the animal's rectum immediately after stunning. Surface samples were collected after removal of the animals from scrap machine, after evisceration, before the refrigeration chamber and from jowls. Samples from the scalding tank water before and after the passage of animals were collected too. The isolates were obtained for microbiological analysis and the confirmation of species was performed by PCR. Strains bands profiles were determined by rep-PCR and compared. Of the 200 samples 19 (9.5%) were positive for Campylobacter, which are all characterized as C.coli. In these isolates, 7 (36.8%) were the rectum, 7 (36.8%) after evisceration and 5 (26.3%) before the refrigeration chamber. Through rep-PCR analysis, it was observed that the animals contaminated by C. coli in the farm may carry the micro-organism through the steps of the flowchart slaughter and the cross contamination also has an important role on the final contamination. The hygienic-sanitary management of care adopted in good manufacturing practices are key in controlling the contamination by C. coli.
