Public concern regarding the use of products with chemicals has increased in Korea, following reports indicating that hazardous chemicals in products, such as disinfectants, can cause fatal lung disease. Despite the widespread use of car colorant products, little is known regarding their potential health risks. The purpose of this study was to determine the potential health risks of substances that exist in car colorant products. Thirteen car colorant products were purchased from the Korean market and 15 commonly used chemicals were analyzed. Exposure and risk assessments were conducted in two assessment stages (screening and refined). The analysis showed that all of the examined products contained toluene, ethylbenzene, and xylene. The maximum concentration of toluene was 52.5%, with a median concentration of 10.8%. Tier 1 (screening) assessment showed that four chemicals (toluene, ethylbenzene, xylene, and 2-butoxyethanol) may pose health risks, but tier 2 (refined) assessment showed that these chemicals do not pose any risk. However, these chemicals were present in all of the examined products, and government regulations did not control their concentrations in these products. Therefore, we suggest that levels of toluene, ethylbenzene, and xylene in car colorant products should be regulated to protect public health.

Abstract Objectives Artisanal cooking pots constructed with recycled aluminum and scrapped car body parts are widely used in the developing world for large scale cooking of food for ceremonies, roadside sells and small-scale food processing. Assessment of the potential health risks of pots fabricated with recycled metal/alloy is the objective of this work Methods Three food stuffs; rice, beans and tomato, and five pots; new aluminum pot (NAP), pitted aluminum pot (PAP), artisan aluminum pot (AAP), stainless steel pot (SSP) and artisan alloy pot (AAY) were used to conduct the study. Each pot was used to cook and store each food item for 0, 12 and 24 h. This mimics the usual style of overnight keeping of cooked food inside these pots. Metal contents of the cooked and stored foods were determined with a spectrophotometer and estimate of health risk was calculated based on the tolerable limits specified by the European Food Safety Authority (EFSA) in 2008.. Specific Release Limit (SRL) of metals based on ALARA principles for food contact material (FCM) was also referenced (Council of Europe, 2013). Results Lead migration into cooked food occurred most (4.32 ± 0.18 mg/kg) in AAY pot and least (0.13 ± 0.05 mg/kg) in SSP while Al migration occurred most in AAP. The mean quantities of Al and Pb ions released by all the pots except SSP into cooked food were above the tolerable limits (Pb = 0.01 mg/kg food; Al = 0.1 mg/kg food). In all cases, metal ion migration increased with increase in food/pot contact time. The average range of Pb content in the food samples were 0.03 to 00.75 mg/kg, 0.23 to 2.63 mg/kg, and 0.84 to 4.19 mg/kg for the raw, cooked and after 24 h storage, respectively. In terms of SRL, AAY and AAP were least favored. Irrespective of pot type used, tomato had the highest level of metal ion content followed by beans and then rice. The work demonstrates that the problem of Pb and Al leaching into cooked food correlates with the type of cooking pot, contact time between food and pot as well as the nature of the foodstuff. Conclusions We conclude that artisanal cooking pots as FCM release Al and Pb ions at potentially toxic levels that poses health risks to the population. Stainless steel surface is suggested as better FCM at all levels of food processing. Our results support the need for countries in the developing world to ban the use of artisanal (uncoated) metal/alloy as FCM. Funding Sources This research was self sponsored.

AbstractMicrobiological studies on chicken meat and carcasses are well documented, but very few studies exist on goose meat and carcasses. Therefore, in this study, dried goose carcass samples were collected from the local households in Kars/Turkey and microbiologically analyzed in terms of public health risks. The total mesophilic viable count was found to be 6.58 (mean log10 CFU g−1) (100%). The number of Enterobacteriaceae was 4.85 (92.8%). Coliform bacteria was counted at the numbers of 2.98 (67.8%), while it was 3.95 (91.1%) for the enterococci, 0.42 (26.7%) for the clostridia, 0.04 (3.5%) for the Clostridium perfringens, and 0.41 (12.5%) for the coagulase positive staphylococci. The numbers of mould and yeast were 0.93 (25%) and 4.81 (94.6%), respectively. Salmonellae and Bacillus cereus could not be isolated in the samples. The results indicate that the dried goose meat samples had poor hygienic quality, contained some of the pathogen microorganisms that are likely to pose a potential health risk.

Abstract Background Food safety in the food market is one of the key areas of focus in public health, because it affects people of every age, race, gender, and income level around the world. The local and international food marketing continues to have significant impacts on food safety and health of the public. Food supply chains now cross multiple national borders which increase the internationalization of health risks. This systematic review of literature was, therefore, conducted to identify common public health risks related to food safety issues in the food market. Methods All published and unpublished quantitative, qualitative, and mixed method studies were searched from electronic databases using a three step searching. Analytical framework was developed using the PICo (population, phenomena of interest, and context) method. The methodological quality of the included studies was assessed using mixed methods appraisal tool (MMAT) version 2018. The included full-text articles were qualitatively analyzed using emergent thematic analysis approach to identify key concepts and coded them into related non-mutually exclusive themes. We then synthesized each theme by comparing the discussion and conclusion of the included articles. Emergent themes were identified based on meticulous and systematic reading. Coding and interpreting the data were refined during analysis. Results The analysis of 81 full-text articles resulted in seven common public health risks related with food safety in the food market. Microbial contamination of foods, chemical contamination of foods, food adulteration, misuse of food additives, mislabeling, genetically modified foods (GM foods), and outdated foods or foods past their use-by dates were the identified food safety–related public health risks in the food market. Conclusion This systematic literature review identified common food safety–related public health risks in the food market. The results imply that the local and international food marketing continues to have significant impacts on health of the public. The food market increases internationalization of health risks as the food supply chains cross multiple national borders. Therefore, effective national risk-based food control systems are essential to protect the health and safety of the public. Countries need also assure the safety and quality of their foods entering international trade and ensure that imported foods conform to national requirements.

This work characterizes the dimension and the exceptionality of 2017 large- and mega-fires that occurred in the center region of Portugal through the assessment of their impact on the ambient levels of particulate matter (PM10 and PM2.5), retrieved from local monitoring stations, and the associated public health risks. PM10 and PM2.5 concentrations were increased during the occurrence of large fires and megafires, with daily concentrations exceeding the European/national guidelines in 7–14 and 1–12 days of 2017 (up to 704 µg/m3 for PM10 and 46 µg/m3 for PM2.5), respectively. PM10 concentrations were correlated with total burned area (0.500 < r < 0.949; p > 0.05) and with monthly total burned area/distance2 (0.500 < r < 0.667; p > 0.05). The forest fires of 2017 took the life of 112 citizens. A total of 474 cases of hospital admissions due to cardiovascular diseases and 3524 cases of asthma incidence symptoms per 100,000 individuals at risk were assessed due to exposure to 2017 forest fires. Real-time and in situ PM methodologies should be combined with protection action plans to reduce public health risks. Portuguese rural stations should monitor other health-relevant pollutants (e.g., carbon monoxide and volatile organic compounds) released from wildfires to allow performing more robust and comprehensive measurements that will allow a better assessment of the potential health risks for the exposed populations.

The need to reduce sugar-sweetened beverage (SSB) consumption is widely accepted, but whether artificially sweetened beverages (ASBs) are a recommended alternative is a growing policy issue because of emerging evidence of potential health effects associated with excess consumption. This study aimed to establish the extent of the Australian population’s knowledge of the risks associated with consuming SSBs (e.g., soda) and ASBs (e.g., diet soda), which is essential for identifying which facets of knowledge to target with public health interventions. A national computer-assisted telephone survey of 3430 Australian adults was conducted in 2017. The survey included a range of measures to test associations between SSB and ASB knowledge and beliefs, demographic characteristics, and soda and diet soda consumption. Participants had an overall awareness that there were health risks associated with SSB and ASB consumption, but they lacked more detailed knowledge of health effects and nutritional composition of these drinks. These knowledge gaps are concerning given that SSBs and ASBs are consumed in large quantities in Australia. Public health interventions targeting consumers’ limited knowledge and perceptions of health risks associated with excess sugar, calorie intake and artificial sweeteners are essential in reducing the health burden of obesity.

Tetrodotoxin (TTX) and its analogues are naturally occurring toxins responsible worldwide for human intoxication cases and fatalities, mainly associated with pufferfish consumption. In the last decade, TTXs were detected in marine bivalves and gastropods from European waters. As TTXs are not regulated or monitored at EU level, their unexpected occurrence in shellfish raised concerns as a food safety hazard and revealed the necessity of a thorough assessment on the public health risks associated with their presence. For this reason, the European Food Safety Authority (EFSA) was requested by the European Commission to provide a scientific opinion, finally adopted in March 2017, according to which a provisional concentration below 44 μg TTX equivalents/kg shellfish meat, based on a large portion size of 400 g, was considered not to result in adverse effects in humans. The EFSA expert panel, however, recognized a number of shortcomings and uncertainties related to the unavailability of sufficient scientific data and provided relevant recommendations for future research to overcome these data gaps identified in order to further refine the risk assessment on TTXs. The present review aims to summarize the knowledge obtained towards addressing these recommendations in the two years following publication of the EFSA opinion, at the same time highlighting the points requiring further investigation.

Grilled foods are important source of acrylamide which has neurotoxic, genotoxic and carcinogenic properties. In the present study, 105 grilled meat and fish foods were analyzed through Gas Chromatography Tandem mass spectrometry (GC-MS/MS) to detect acrylamide concentrations in Bangladesh. The average acrylamide contents in grilled chicken, tandoori chicken, chicken tikka kabab, chicken fry, beef kabab, beef grill, grilled fish were 80.27µg/Kg, 99.34µg/Kg, 83.13 µg/Kg, 73.98 µg/Kg, 68.19 µg/Kg, 81.52 µg/Kg and 48.39 µg/Kg respectively. The differences in the acrylamide contents in the products of same category were because of differences in thermal treatments during the preparation. In comparison with other studies, the results suggested that, consumption of those foods is safe for the consumers. This study will focus light on the fate of acrylamide during food processing and provide valuable information to access potential health risks through consumption of those foods.

Staphylococcal foodborne intoxication, in which major symptoms are vomiting and diarrhoea, occurs after ingestion of thermostable staphylococcal enterotoxins produced in food by enterotoxigenic strains of coagulase-positive staphylococci. Staphylococcal enterotoxins are normally not or only slightly inactivated during food processing, storage, distribution or during the preparation of the food in the kitchen. Therefore, if enterotoxigenic staphylococci are able to grow in food to more then 105 - 106 cfu/g/ml before they are killed there is still a risk of intoxication with consumption. The legislation of the Republic of Serbia lays down criteria for coagulase- positive staphylococci in food. However, the number of coagulase-positive staphylococci may not always be a good indicator of the presence of staphylococal enterotoxins, and the number of cells may have already decreased although the product still contains enterotoxins. The microbiological criteria for coagulase-positive staphylococci and/or staphylococcal enterotoxins in food are essential and useful to protect public health.

Abstract Constructed wetlands are popular tools for managing threatened flora and fauna in urban settings, but there are concerns that these habitats may increase mosquito populations and mosquito-related public health risks. Understanding the interactions occurring between mosquitoes of public health concern and co-occurring organisms is critical to informing management of these habitats to mitigate potential health risks and balance the multiple values of urban wetlands. This study examined how oviposition behavior of Culex annulirostris Skuse, the most important pest mosquito species associated with freshwater wetland habitats in Australia, is influenced by the presence of Gambusia holbrooki Girard, a widespread invasive fish. Water was collected from urban wetlands that are intensively managed to reduce G. holbrooki populations to assist conservation of locally threatened frogs, and adjacent unmanaged wetlands where G. holbrooki was abundant. Laboratory experiments were conducted to examine the oviposition response by Cx. annulirostris to water samples from these two habitats. Experiments were conducted on two occasions, once in February following draining and refilling of the urban wetlands, and repeated following a substantial rainfall event in March. The results clearly demonstrate that ovipositing mosquitoes were able to detect and avoid water derived from habitats containing fish, even in the absence of the fish themselves. Understanding how invasive species affect the behavior and spatial distribution of pest species such as Cx. annulirostris will enable future wetland design and management to maximize benefits of urban wetlands and minimize potential public health risks.
