Food hygiene knowledge in adolescents and young adults

Purpose – The purpose of this paper is to utilise the comprehensive Food Safety Knowledge Instrument to compare food hygiene knowledge across a population of high school and university students in Australia and the UK. Design/methodology/approach – In total, 475 students from secondary schools and universities in Australia and the UK took part in a survey, which included a Food Safety Knowledge Instrument and demographic items. Findings – Food safety knowledge was generally very low. High school students had a mean score of only 38 per cent, while university students just reached a “pass” with a mean of 54 per cent. Demographics accounted for 41 per cent of variance in food knowledge scores. Female gender, being at university rather than high school, and living out of home rather than with parents were associated with greater food knowledge. Residing in Australia rather than the UK and being older were also associated with greater knowledge; however, these findings were subsumed by education group. Socio-economic status was not a significant predictor of food knowledge. Practical implications – Identifying demographic and cultural differences in food knowledge can help to identify at-risk populations to better target in theory and knowledge-based interventions. Originality/value – This study is the first to apply the knowledge instrument in an Australian population. Understanding the baseline knowledge in this population is an important first step at developing effective interventions for food safety.

An industry viewpoint on the role of farm assurance in delivering food safety to the consumer: the case of the dairy sector in England and Wales

Food safety, alongside food quality, remains a primary concern of both consumers and those along the whole food supply chain, leading to regulation by government alongside private third party certification. Much has been written about the value of these systems primarily from the perception of the consumer. This paper reports on a study that examined industry perceptions on the regulatory and assurance systems within the dairy sector of England and Wales. It found that the primary producer found value in both systems, although from a food hygiene focus regulation was seen to be more rigorous. Other stakeholders along the dairy food supply chain saw the assurance scheme as more rigorous. All stakeholders recognised the need to reduce duplication in delivering food safety through combining key elements of both systems with the added potential for better communication of both food safety and quality to the final consumer.

Food, nutrition and public health in contemporary Spain, 1900-1936

Within the context of the health reforms introduced in Spain in the early 20th century and the influence of international health organisations on their development, this article analyses the growing interest that surrounded nourishment and food-related problems at that time in relation to healthcare, the diagnosis provided by hygienists of such problems, and the public health measures applied to resolve them. The issue of hygienic diet and the collective aspect of nutritional problems became priorities in the field of healthcare. Two of the most prominent initiatives involved setting up a Department of Nutrition and Food Hygiene and Bromatological Technique during the early years of the Second Republic, as part of the National School of Health, as well as a Food Hygiene Service. Spanish hygienists underlined the importance of education and the dissemination of information about food hygiene, health and nutrition, in order to overcome the qualitative and quantitative deficiencies observed in the average diet of the Spanish population.

Hygienic practices among food vendors in educational institutions in Ghana: the case of Konongo

With the booming street food industry in the developing world there is an urgent need to ensure food vendors adhere to hygienic practices to protect public health. This study assessed the adherence to food hygiene practices by food vendors in educational institutions in Konongo, Ghana. Structured questionnaires, extensive observation and interviews were used for the study involving 60 food vendors from 20 basic schools. Attributable to the influence of school authorities and the level of in-training of food vendors, the study points out that food vendors in educational institutions generally adhered to good food hygiene practices, namely, regular medical examination (93%), protection of food from flies and dust (55%); proper serving of food (100%); good hand hygiene (63%); and the use of personal protective clothing (52%). The training of food vendors on food hygiene, instead of the level of education had a significant association (p < 0.05) with crucial food hygiene practices such as medical examination, hand hygiene and protection of food from flies and dust. Further, regulatory bodies legally mandated to efficiently monitor the activities of food vendors lacked the adequate capacity to do so. The study proposes that efforts should be geared towards developing training programmes for food vendors as well as capacity building of the stakeholders.

Design and setting: A questionnaire to examine nutrition-related issues and practices was mailed to care providers registered in the southern region of Adelaide, South Australia. Care providers also supplied a descriptive, qualitative recall of the food provided by parents or themselves to each child less than five years of age in their care on the day closest to completion of the questionnaire. Subjects: 255 care providers. The response rate was 63% and covered 643 preschool children, mean 4.6 (SD 2.8) children per carer. Results: There was clear agreement that nutrition promotion was a relevant issue for Family Day Care providers. Nutrition and food hygiene knowledge was good but only 54% of respondents felt confident to address food quality issues with parents. Sixty-five percent of respondents reported non-neutral approaches to food refusal and dawdling (reward, punishment, cajoling) that overrode the child's control of the amount eaten. The food recalls indicated that most children (> 75%) were offered fruit at least once. Depending on the hours in care, (0 to 4, 5 to 8, greater than 8 hours), 20%, 32% and 55%, respectively, of children were offered milk and 65%, 82% and 87%, respectively, of children were offered high fat and sugar foods. Conclusions: Questionnaire responses suggest that many care providers are committed to and proactive in a range of nutrition promotion activities. There is scope for strengthening skills in the management of common problems, such as food refusal and dawdling, consistent with the current evidence for approaches to early feeding management that promote the development of healthy food preferences and eating patterns. Legitimising and empowering care providers in their nutrition promotion role requires clear policies, guide lines, adequate pre- and in-service training, suitable parent materials, and monitoring.

Avaliação microbiológica, detecção e susceptibilidade a antimicrobianos de potenciais enteropatógenos das famílias Enterobacteriaceae e Vibrionaceae em mexilhões Perna perna da praia de Itaipu, Niterói-RJ

Por serem organismos filtradores, os mexilhões devem ser extraídos para consumo somente de águas com padrões microbiológicos regulamentados pelo Conselho Nacional do Meio Ambiente, uma vez que intoxicações alimentares de origem bacteriana são as consequências mais comuns relacionadas ao consumo destes moluscos. Após a retirada dos costões, estes organismos passam por processos de fervura, lavagem, acondicionamento em sacos plásticos e transporte até a chegada ao mercado onde são comercializados; etapas estas, realizadas sem cuidados assépticos. Objetivando avaliar a qualidade microbiológica de mexilhões Perna perna coletados na praia de Itaipu, Niterói, RJ; após a sua fervura; e comercializados no Mercado São Pedro, foram realizadas contagens de coliformes totais e termotolerantes e pesquisa de Escherichia coli, Salmonella spp. e Vibrio spp. por metodologia convencional e molecular em amostras obtidas destes locais. Pelo teste de disco-difusão foi observado o perfil de resistência das cepas isoladas. Do total de amostras analisadas (27) apenas 3 dos mexilhões que sofreram processo de aferventação, 1 do comercializado e 3 do in natura, se encontravam dentro dos padrões aceitáveis pela legislação. Não houve diferença significativa entre as contagens de coliformes termotolerantes dos diferentes mexilhões analisados, mas sim entre os períodos seco e chuvoso. Somente uma das nove coletas de água mostrou-se própria para o cultivo de mexilhões (até 14 CF/mL). Foram isoladas e caracterizadas fisiológicamente, 77 estirpes da espécie E. coli, sendo confirmadas molecularmente por PCR os sorotipos EPEC, STEC e EAEC; 4 cepas Salmonella spp. sendo apenas uma confirmada por PCR; e das 57 cepas caracterizadas como Vibrio spp., 51 foram confirmadas por PCR, sendo 46 Vibrio spp., 2 V. cholerae, 1 V. vulnificus, 1 V. parahaemolyticus e 1 V. mimicus. Entre as estirpes de E. coli, 13% apresentaram multirresistência e 15,6% apresentaram resistência múltipla. A estirpe de Salmonella spp. se mostrou sensível a todos os antimicrobiados testados. Das estirpes de Vibrio spp. testadas, 68,6% apresentaram multirresistência e 72,5% apresentaram resistência múltipla. A partir da pesquisa de genes direto do caldo de enriquecimento foi possível detectar todos os genes pesquisados, com exceção para os sorotipos de Salmonella e V. cholerae. Baseado nos resultados do presente trabalho pode-se inferir que os mexilhões, amplamente comercializados no município de Itaipú, podem se constituir em risco para a saúde pública dos consumidores no Rio de Janeiro, necessitando dos órgãos competentes uma eficiente fiscalização nos pontos de venda e cultivo destes moluscos.

Arsenic accumulation and metabolism in rice (Oryza sativa L.)

The use of arsenic (As) contaminated groundwater for irrigation of crops has resulted in elevated concentrations of arsenic in agricultural soils in Bangladesh, West Bengal (India), and elsewhere. Paddy rice (Oryza sativa L.) is the main agricultural crop grown in the arsenic-affected areas of Bangladesh. There is, therefore, concern regarding accumulation of arsenic in rice grown those soils. A greenhouse study was conducted to examine the effects of arsenic-contaminated irrigation water on the growth of rice and uptake and speciation of arsenic. Treatments of the greenhouse experiment consisted of two phosphate doses and seven different arsenate concentrations ranging from 0 to 8 mg of As L(-1) applied regularly throughout the 170-day post-transplantation growing period until plants were ready for harvesting. Increasing the concentration of arsenate in irrigation water significantly decreased plant height, grain yield, the number of filled grains, grain weight, and root biomass, while the arsenic concentrations in root, straw, and rice husk increased significantly. Concentrations of arsenic in rice grain did not exceed the food hygiene concentration limit (1.0 mg of As kg(-1) dry weight). The concentrations of arsenic in rice straw (up to 91.8 mg kg(-1) for the highest As treatment) were of the same order of magnitude as root arsenic concentrations (up to 107.5 mg kg(-1)), suggesting that arsenic can be readily translocated to the shoot. While not covered by food hygiene regulations, rice straw is used as cattle feed in many countries including Bangladesh. The high arsenic concentrations may have the potential for adverse health effects on the cattle and an increase of arsenic exposure in humans via the plant-animal-human pathway. Arsenic concentrations in rice plant parts except husk were not affected by application of phosphate. As the concentration of arsenic in the rice grain was low, arsenic speciation was performed only on rice straw to predict the risk associated with feeding contaminated straw to the cattle. Speciation of arsenic in tissues (using HPLC-ICP-MS) revealed that the predominant species present in straw was arsenate followed by arsenite and dimethylarsinic acid (DMAA). As DMAA is only present at low concentrations, it is unlikely this will greatly alter the toxicity of arsenic present in rice.

Educação alimentar e nutricional no livro didático : análise dos livros do 8º ano do ensino fundamental das escolas públicas de sobral-CE

A Educação Nutricional é conceituada como um processo educativo no qual, através da união de conhecimentos e experiências do educador e do educando, vislumbra-se tornar os sujeitos autônomos e seguros para realizarem suas escolhas alimentares de forma que garanta uma alimentação saudável e prazerosa, propiciando, o atendimento de suas necessidades fisiológicas, psicológicas e sociais. Embora a prática pedagógica do professor envolva diversas dimensões, como sua pesquisa constante para o aprimoramento de seu trabalho, um livro didático com textos adequados, ilustrações pertinentes e informações atualizadas auxiliam no planejamento de ensino. Nesta dissertação apresenta-se um estudo exploratório que tem por objetivo analisar os conteúdos de Educação Alimentar e Nutricional em livros didáticos de Ciências do 8º ano adotados em escolas públicas brasileiras. Os manuais pesquisados são referentes ao triênio 2011-2013. A análise dos livros didáticos realizou-se de acordo com as seguintes categorias: nutrientes, higiene de alimentos, conservação de alimentos e saúde. A carência de material encontrado nos livros didáticos ou sua inadequação em relação às referências especializadas sugere que os docentes tenham capacitação na área de Educação Nutricional, para assim, passarem a escolher materiais de base que se aperfeiçoem às suas necessidades e procedimentos de trabalho em sala de aula.

Variação das características físico-químicas e microbiológicas das salmouras empregadas na salga de queijos tipo mussarela durante o período de sua utilização

Foram analisadas 40 amostras de salmouras empregadas na salga por submersão de queijos tipo mussarela, em uma indústria de laticínios do Estado de São Paulo, Brasil, com o objetivo de se conhecer a variação das características físico-químicas e microbiológicas durante o período de sua utilização. Os valores médios do pH, concentração de cloreto de sódio e de proteínas solúveis, desde o preparo da salmoura até o 21° dia de utilização, variaram de 7,21 a 5,76, 27,1 a 24,5 e de zero a 0,126 mg/ml, respectivamente. Por outro lado, os valores médios das contagens de microrganismos mesófilos e do número mais provável de coliformes totais e de origem fecal variaram de 5,8 x 10 UFC/ml a 6,9 x 10(4) UFC/ml, zero a 1,6 x 10(5)/100ml e zero a 1,1 x 10(5)/100ml, respectivamente. Além disso, os valores médios das contagens de bolores e leveduras e de Staphylococcus coagulase positiva, variaram de 0,4 x 10 UFC/ml a 2,0 x 10³ UFC/ml e de zero a 1,3 x 10 UFC/ml, respectivamente. Os resultados encontrados sugerem a existência de condições higiênicas inadequadas durante o preparo e utilização das salmouras, de modo a representar uma importante fonte de contaminação para os queijos. em decorrência deste fato, existe a possibilidade do comprometimento da qualidade dos queijos, de modo a representar risco potencial à população consumidora.
