The process of ensuring the safety of the food supply is dynamic. Both the possibility of contamination and the effectiveness of safety precautions are impacted by changes in the kinds of food consumed, the geographical origins of food products, and the methods by which these foods are processed. For instance, compared to earlier generations, consumers’ general understanding of safe food preparation and handling techniques has decreased due to a higher reliance on prepackaged convenience foods. Nowadays, consumers depend increasingly on other people to make sure the food they eat is safe. Growing consumption of minimally processed foods and growing imports of fresh products from other nations have resulted from changes in consumer tastes and food processing technologies. This review aims to critically synthesize existing knowledge on microbial risks in food, focusing on their sources, mechanisms of contamination, risk evaluation methodologies, and implementation of food safety measures. Major foodborne pathogens, including <i>Salmonella</i>, <i>Escherichia coli</i>, <i>Listeria monocytogenes</i>, and <i>Norovirus</i>, are discussed alongside factors influencing their survival and transmission. Today <i>Clostridium botulinum</i>, <i>Staphylococcus aureus</i>, and <i>Salmonella</i> spp. remain among the major foodborne pathogens, but during the last two decades food-borne diseases such as shigellosis, listeriosis, campylobacteriosis, and diseases caused by pathogenic strains of <i>Escherichia coli</i> have become increasingly salient. These new concerns necessitate continued investment in research and technology development to improve the safety of the food supply. The review highlights current approaches to microbiological risk assessment, regulatory frameworks, and control strategies, while also addressing emerging challenges such as antimicrobial resistance, biofilms, and ready-to-eat foods. By integrating risk evaluation with practical implementation strategies, this review provides valuable insights for researchers, regulators, and food industry stakeholders seeking to strengthen food safety systems and reduce the burden of foodborne diseases.

Abstract Background Wildland fires in the United States have increased in frequency and scale over the past 30 years exposing millions of people to hazardous air pollutants. Among others, aging individuals are particularly vulnerable to the effects of wildfire smoke. In this study, we assessed the neurobiological impacts of wood smoke (WS) on aged mice and the potential of anti-aging therapeutics to mitigate these impacts. Methods Female C57BL/6 J mice, aged 18 months, were divided into 10 groups and exposed to either filtered air (FA; 5 groups) or biomass derived WS (5 groups) for 4 h/day, every other day, for 14 days (7 exposures total) with an average particulate matter (PM) concentration of 448 µg/m3 per exposure. One FA control group and one WS exposed group were euthanized 24 h after the last exposure. The remaining 8 groups (4 FA and 4 WS exposed) were treated with either vehicle control, resveratrol and nicotinamide mononucleotide (RNMN), dasatinib and quercetin (DQ), or both RNMN and DQ (RNDQ) for 10 weeks. Results A significant reduction in NAD + within the prefrontal cortex was observed following the 14-day exposure to WS along with a reduction in serotonin. Serotonin reductions were observed up to 10 weeks post-exposure and co-occurred with neuroinflammation and behavioral alterations, including increased immobility in a forced swim test. RNMN conferred the greatest mitigating effect after WS exposure, while RNDQ treatment resulted in an upregulation of markers associated with aging in the brain. While the metabolic shift in the PFC following WS exposure was relatively modest, mice exposed to FA and vehicle control (10 weeks of natural aging) exhibited the greatest metabolic shift, including perturbed nicotinamide metabolism. Conclusion Taken together, these findings highlight that subacute (14-day) exposure to WS results in persistent neurometabolomic and behavioral alterations in an aged mouse model and that intervention with RNMN may be a useful strategy to mitigate the adverse neurological outcomes observed. Further studies are needed to assess the specific impact of either resveratrol or NMN in isolation and to fully elucidate age-specific, as well as sex- and species-determinant, WS exposure response pathways.

Introduction: Occupational health and safety are important for professionals managing an organization’s workplace accident insurance efforts because their work influences productivity. Therefore, this study will compare the associated health and burnout related to work in case managers and administrators. Methods: A longitudinal design was adopted. This study used year-over-year surveys of 158 employee professionals with 79 case managers and 79 administrators over a two-year time frame. They measured occupational health with the questionnaires Work Ability Index (WAI) and Copenhagen Burnout Inventory (CBI). Occupational health was subsequently studied using linear regression and mixed-effects models. Results: Case managers tend to have higher work ability (mean WAI score: 45.08), but they suffer from more personal burnout (mean PB score: 33.0), presumably because they work directly with injured workers. In contrast, administrators are experiencing lower but more stable levels in their work ability (mean WAI score: 37.78) and with higher levels of client-related burnout (mean CRB score: 53.0). Further, work ability deteriorates as age increases, especially among case managers, and is negatively associated with high BMI, low sleep and long sick leave. Employees with a BMI > 30 had 12% lower WAI scores (p<0.01), and those sleeping < 6 hours per night had 15% lower work ability index. Conclusion: This study emphasizes the need for targeted interventions to alleviate occupational burnout and improve work ability, particularly through occupation-specific workplace interventions. The study also suggests that implementing stress management programs, health promotion initiatives, and workflow optimizations may improve occupational health outcomes.

Introduction: The 2022 National Occupational Health and Safety (OHS) Profile in Indonesia shows that the human factor in safety is a factor that influences the risk of workplace accidents. The mining accidents statistical data in Indonesia, in which there was a 100% increase of workplace accidents in 2022, have given this industry an urgency to get a special attention to study risk-taking behavior at the workplace. At the organizational level, PT. XYZ (a mining contractor company in Indonesia) has internally measured its safety maturity level and is currently in calculative level, which indicates that the OHS management system has been implemented but the number of unsafe behaviors and unsafe conditions on site is still high. This paper explores quantitative results from research which aims to obtain an overview of employees’ internal factors leading to rule-breaking acts at the workplace. Methods: This paper uses cross-sectional design research with quantitative approach. Using stratified random sampling, a sample of 283 employees of PT. XYZ Site A participated in this study, ranging from managers, supervisors, and workers. Data were collected through a questionnaire with open-ended questions referring to a study from Safe Work Australia and analyzed quantitatively using statistical Chi-Square statistical test. Results: From the results of the Chi-Square test, the independent variables that have a value of Asymp. Sig. (2-sided) below 0.05 (95% CI) and lead to rule-breaking act at workplace are risk-taking behavior acceptance (0.018), normalizing minor accidents (0.002), and decision to take risk (0.000). Conclusion: Employees’ internal factors of risk-taking behavior acceptance, normalizing minor accidents, and decision to take risk have positive and significant effect on rule-breaking acts at the workplace. It is recommended that organizations implement a proper risk management with ALARP principle, safety empowering leadership, and safe behavior trainings to minimize rule-breaking acts at the workplace

Safety and health at work are fundamental aspects to promote the care and protection of the working population and adequately in welfare and permanence of good physical and mental health in the food sector, as well as in the industrial sector. There are specific risks that require presence (COPASST), attention and preventive measures to ensure optimal safe and healthy conditions. It is essential to have training and education programs for employees, in order to become aware of the risks associated with their work and to teach them the necessary preventive measures to minimize and act in safe conditions.This includes training in the handling of equipment and machinery, as well as proper food handling and storage. It is also important to emphasize and maintain standards of hygiene and cleanliness in all process areas. This implies the implementation of regular cleaning protocols, the use of personal protective equipment (PPE), and the promotion of a culture of use and handling of chemical substances.It is also necessary to evaluate and control the chemical, biological and physical risks present in the work environment. This involves identifying hazardous substances and contaminating agents to strengthen measures to minimize direct exposure, as well as excellent ventilation and the correct use of personal protective equipment.

Automatic feeding systems are not common in Russia. To find the optimal solution for the development of an automatic feed wagon on the basis of FSAC VIM, the authors made a review of the scientific works of foreign scientists describing the industrial experience of operating automatic feeding systems and evaluating their effectiveness. Automatic feeding systems (AFS) have a number of advantages as compared with the traditional feeding system based on mobile TMR feeder-mixers. AFS can double reduce labor costs of the preparation and distribution of feed mixtures on cattle farms; increase the accuracy of feeding by dividing animals into a larger number of technological groups receiving different feeding rations depending on productivity, lactation stage, etc.; ensure the frequency of feeding cattle up to six to eight times a day (which favorably affects their health and milk productivity). Automatic feeding systems improve animal welfare and hygiene. The feed alley on farms equipped with AFS is almost two times narrower than on farms using mobile TMR mixers, which makes it possible to use the cowshed area more efficiently. The main disadvantage of AFS is their high cost - on average 1,230 €/head, with an average cost of using a system based on mobile TMR mixers of 400 €/head. In the existing AFS, storage containers account for most of the investment costs. To reduce the cost, the authors put forward the concept of an automatic feeding system based on an automatic feed wagon with a storage container for intermediate storage of ready-made feed mixtures. It can be loaded with a mobile TMR mixer

Background & Aims: Despite the relative comfort and welfare today’s modern technology has brought to humankind, it has also been the basis for the emergence of risks and threats. These risks and risk factors should be assessed and controlled using systematic risk assessment and management methods. Numerous techniques and methods have been developed to analyze risks, each of which has its own strengths and weaknesses. One of the system risk analysis techniques, which is among qualitative techniques and identifies and analyzes system risks inductively, is the functional hazard analysis (FuHA) technique. The present study aims to identify and control risks that occur due to technical defects or system dysfunctions and can lead to an unpleasant event, as occurred in an industrial unit in 2016. Methods: In this cross-sectional analytical study, the functional risks of an industrial unit were analyzed using the FuHA technique. By implementing the FuHA technique in the investigated industrial unit, 17 functional defects were identified. Results: In general, according to the level of severity of different consequences caused by the identified defects, 60 functional risks were identified, of which 7 cases (11.67%) were assessed as unacceptable, 17 cases (28.33%) as unfavorable, and 36 cases (60%) as acceptable but needing revision. Conclusion: The results of this study showed that the FuHA technique had a favorable ability to identify and analyze system and subsystem functional risks, especially software subsystems.

OBJECTIVES Reports of workers' casualties include occupational low back pain (LBP), accounting for approximately 60% of compensable occupational disease. While LBP has become an important safety and health problem, the occurrence of occupational LBP has not been analyzed recently. This study aimed to evaluate the occurrence of occupational LBP in reports of workers' casualties between 2018 and 2019. METHODS The study included 10,208 cases of occupational LBP (2018, n = 5,043; 2019, n = 5,165). Data on the location and date of industrial accidents, as well as type and size of business, age, sex, and leave period of the victims were tabulated. RESULTS The number of occupational LBP cases was the highest in the health and hygiene industry (31.3%), followed by the commercial, manufacturing, and transportation industries. In the health and hygiene industry, social welfare facilities were listed in 24.3% of the total cases, and many caregivers suffered from LBP. Occupational LBP cases were less in cold regions and few during the cold period between November and January. Several occupational LBP cases occurred on Mondays following a holiday, and approximately 40% occurred between 9 a.m. and 12 a.m. Occupational LBP was frequently reported in workplaces with a volume of 10-49 workers, such as social welfare facilities in terms of business type. In terms of work-related accident victims per 100,000 workers, women were slightly more prone to LBP than men, and most of them were in their 20s and 30s. Approximately 60% of the leave period taken by victims was 2 weeks maximum. CONCLUSIONS Occupational LBP was experienced by most workers in workplaces with at least 10-49 workers, such as social welfare facilities, between 2018 and 2019. In addition, LBP was more common in women than in men. Most workers with LBP take a leave period of 2 weeks. Suitable measures should be taken to prevent occurrences of occupational LBP.

Introduction: Naphthalene is a chemical exposure found in various industries, including in the manufacture of phthalic anhydride, synthetic resins, lubricants, mothballs, and used as fuel additives. The exposure to naphthalene in humans has several detrimental health effects such as hemolytic anemia, kidney and liver disorders. Therefore, biological monitoring is needed as a health surveillance of naphthalene exposure. Generally, the biomonitoring examination carried out for this is naphthol in the blood. However, 1,2-dihydroxynaphthalene (1,2-DHN) is also known to be another major metabolite. Therefore, this literature review aims to determine whether 1,2-DHN can also be a reliable biomonitoring test on occupational exposure to naphthalene. Methods: PubMed, Proquest, and Google Scholar were used to conduct article searches. The articles were chosen based on predetermined inclusion and exclusion criteria. The selected articles were then critically appraised. Results: Four cross-sectional articles examining 1,2-DHN in the urine of naphthalene-exposed workers were selected and reviewed. There was a similar result from all selected articles that elevated levels of 1,2-DHN in the urine, indicating workplace exposure to naphthalene. Moreover, apart from having a strong correlation with 1- and 2-naphthol, 1,2-DHN also has a high sensitivity compared to these established metabolites. Conclusion: Based on the articles obtained, 1,2-DHN can be a reliable biological monitoring for workers exposed to naphthalene. However, further research is still needed on other industries exposed to naphthalene and is needed to ascertain the correlation between external and internal exposure to naphthalene.

Background Despite the lack of official COVID-19 statistics, various workplaces and occupations have been at the center of COVID-19 outbreaks. We aimed to compare legal measures and governance established for managing COVID-19 infection risks at workplaces in nine Asia and Pacific countries and to recommend key administrative measures. Methods We collected information on legal measures and governance from both general citizens and workers regarding infection risks such as COVID-19 from industrial hygiene professionals in nine countries (Indonesia, India, Japan, Malaysia, New Zealand, Republic of the Philippines, Republic of Korea, Taiwan, and Thailand) using a structured questionnaire. Results A governmental body overseeing public health and welfare was in charge of containing the spread and occurrence of infectious diseases under an infectious disease control and prevention act or another special act, although the name of the pertinent organizations and legislation vary among countries. Unlike in the case of other traditional hazards, there have been no specific articles or clauses describing the means of mitigating virus risk in the workplace that are legally required of employers, making it difficult to define the responsibilities of the employer. Each country maintains own legal systems regarding access to the duration, administration, and financing of paid sick leave. Many workers may not have access to paid sick leave even if it is legally guaranteed. Conclusion Specific legal measures to manage infectious disease risks, such as providing proper personal protective equipment, education, engineering control measures, and paid sick leave are recommended to be stipulated in Industrial safety and health-related acts.

Introduction: Since the outbreak of the Ebola virus, its design has constantly been evolving to serve the purpose of protection without hampering the efficiency. In a study conducted in 2019, before the advent of COVID 19, it was found that performing precarious laboratory or clinical works while wearing PPE involved various restrictions compared to the same work without PPE.  The objective of this study is to identify the influence of personal protective equipment on physiological parameters and the individual wellbeing of healthy workers. Methods: This Pilot Quasi-experimental study was performed on 12 volunteers fitting the inclusion criteria. Candidates were seated comfortably and their baseline resting pulse rate, respiratory rate, oxygen saturation via pulse oximeter, blood pressure, and End-tidal CO2 were recorded via a portable monitor. All candidates were asked to wear a KN95 mask along with a 3 ply mask over it and wear anti-fog goggles. All the above-mentioned parameters were recorded again after five minutes of comfortable sitting and ten minutes of brisk walk. Result:   Significant difference is found between resting EtCO2 and after wearing of PPE (P = 0 .044). After a brief exercise, the further rise in EtCO2 is also significant (P = 0.002).  There is no significant rise in pulse after wearing PPE (P = 0.092) but on exertion after wearing PPE, the rise in pulse is statistically significant (P = 0.002). The rest of the variables, such as the rise in respiratory rate, blood pressure, and fall in oxygen saturation rise has no statistical significance. Conclusion: Personal protective equipment has proven to rise in end-tidal carbon dioxide and tachycardia, which can lead to headache, dizziness, and respiratory discomfort. All of the factors can hamper the health care workers' performance and can adversely affect their efficiency. Keywords: covid-19, end tidal CO2, personal protective equipment, physiological

Introduction: Work-related fatigue on workers are usually caused by some factors such as individual characteristics (age, work period, nutritional status) and rest break. This research aims to analyze the correlation between individual characteristics and rest break with work-related fatigue on telecommunication network service workers. Method: This research used an observational analytic and a cross-sectional approach. The population and sample in this research were all 32 workers at I-OAN unit in a telecommunication network service company. The independent variables in this study were age, work period, nutritional status, and rest break, while the dependent variable was work-related fatigue. Data were obtained throughquestionnaires about individual characteristics (age, work period, nutritional status) and rest break filled by workers. The data were also obtained through the Industrial Fatique Research Committee (IFRC) questionnaires filled by workers. All of the data in this study were analyzed with the Spearman correlation test (α = 0.05). Results: The majority of I-OAN unit workers are in the age range of 25-29 years (46.9%), have 3-4 years of work period (56.2%), and have normal nutritional status (40.6%). For the rest break variable, there are16 workers (50%) who have <30 minutes rest break and also 16 workers (50%) who have ≥ 30 minutes rest break. Conclusion: There is a correlation between individual characteristics and rest break with work-related fatigue on telecommunication network service workers. Keywords: individual characteristics, rest break, work-related fatigue

Introduction: The pandemic of COVID-19 has major effects, particularly on hospitals and health workers. At the beginning of March, more than 3,300 health workers have beencontracted with COVID-19 as reported by China's National Health Commission. Twenty percent of healthcare workers in Italy have also also infected and some died. To minimize the risk of transmission to health workers, knowledge of the risk factors that influence the transmission is needed. Thus, this study aims to determine risk factors related to occupational safety and health for healthcare workers during the COVID-19 pandemic. Methods: The literature was searched on Pubmed, Google Scholar, WHO, and the Ministry of Health instruments were implemented. 8 relevant studies were reviewed. Results: According to the analysis results of several studies, the use of PPE that is less consistent and not suitable with the risk of exposure will increase the risk of infection. The risk of infection is also increased by poor hand hygiene. According to the Kaplan-Meier curve, the working duration of ≥ 15 hours will increase the risk of infection. The risk of infection also exists for health workers who carry out risky procedures that generate airborne particles such as resuscitation, as well as environmental factors such as negative pressure rooms and traffic control bundling. Conclusion: Risk factors related to occupational health and safety during this COVID-19 pandemic for healthcare staff are: compliance with the use of PPE, hand hygiene, working hours duration, risky procedures, and environmental factors. Keywords: healthcare workers, occupational safety, COVID-19, personal protective equipment

Individuals living in general indoor environments are exposed to a greater variety of chemical pollutants, albeit at lower concentrations, compared with industrial workers in occupational environments. These pollutants can result in a variety of adverse health effects, including those affecting the respiratory, neurological, reproductive, dermatologic, and cardiovascular systems. In Japan, indoor air quality guidelines have been established for 13 chemicals since 1997, and these developments have continued on the basis of scientific discussions in the Committee on Indoor Air Pollution (CIAP) that was set up by the Ministry of Health, Labour and Welfare. However, the types and concentrations of these pollutants have been observed to be inconsistent over time due to lifestyle changes and the development of novel household products and building materials. Therefore, continuing the monitoring of indoor chemicals and the development of indoor air quality guidelines for substances that pose potential high health risks are essential for the protection of public health. In indoor environments, there are multiple media by which humans come in contact with indoor chemicals and multiple exposure pathways that can affect human health, particularly for semi-volatile organic compounds (SVOCs). This is defined as aggregate exposure. Furthermore, combined exposure to multiple low-level pollutants occurs in indoor environments. In this article, a comprehensive overview of the indoor air quality guidelines in Japan and assessment approaches for developing indoor air quality guidelines is provided. In addition, future issues facing approaches for indoor chemicals, including aggregate exposure to SVOCs and combined exposure to multiple pollutants with common toxicological effects in indoor environments, are discussed.

Introduction. The mining and metallurgical industries form the basis of the economy of the Murmansk Region. Working conditions at industrial enterprises, combined with extreme climatic conditions of the Arctic, pose an increased risk of occupational diseases. The purpose of the study was to investigate working conditions and occupational disease rates among industrial workers of the Murmansk Region in 2007–2017. Materials and methods. We studies socio-hygienic monitoring data on working conditions and occupational diseases in the population of the Murmansk Region in 2007-2017 provided by the Federal Center for Hygiene and Epidemiology of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare, Moscow. Results. In 2008-2017, the most common occupational risk factors in the Murmansk Region included noise (25.8%), job strain (17.8%), and chemical factor (12.6%) while 39.2% of workers were exposed to a combination of occupational hazards. Over 10 years, the absolute number of workers exposed to dangerous and hazardous industrial factors decreased by 1.8 times. In the Murmansk Region, 84.3% of occupational disease cases were registered among workers of mining and metallurgical enterprises. In 2007-2017, the region experienced a significant decrease in occupational disease incidence mainly related to job cuts. The role of other factors (improvement of working conditions, health promotion) needs to be clarified; yet, it is possible to predict their positive influence on occupational morbidity in the next few years. Conclusion. To achieve a substantial decrease in occupational disease incidence rates, it is essential to keep improving comprehensive measures aimed at preserving workers’ health in the Murmansk Region.

Abstract Background Caloric restriction (CR) is known to improve health and extend lifespan in human beings. The effects of CR on adverse health outcomes in response to particulate matter (PM) exposure and the underlying mechanisms have yet to be defined. Results Male C57BL/6 J mice were fed with a CR diet or ad libitum (AL) and exposed to PM for 4 weeks in a real-ambient PM exposure system located at Shijiazhuang, China, with a daily mean concentration (95.77 μg/m3) of PM2.5. Compared to AL-fed mice, CR-fed mice showed attenuated PM-induced pulmonary injury and extra-pulmonary toxicity characterized by reduction in oxidative stress, DNA damage and inflammation. RNA sequence analysis revealed that several pulmonary pathways that were involved in production of reactive oxygen species (ROS), cytokine production, and inflammatory cell activation were inactivated, while those mediating antioxidant generation and DNA repair were activated in CR-fed mice upon PM exposure. In addition, transcriptome analysis of murine livers revealed that CR led to induction of xenobiotic metabolism and detoxification pathways, corroborated by increased levels of urinary metabolites of polycyclic aromatic hydrocarbons (PAHs) and decreased cytotoxicity measured in an ex vivo assay. Conclusion These novel results demonstrate, for the first time, that CR in mice confers resistance against pulmonary injuries and extra-pulmonary toxicity induced by PM exposure. CR led to activation of xenobiotic metabolism and enhanced detoxification of PM-bound chemicals. These findings provide evidence that dietary intervention may afford therapeutic means to reduce the health risk associated with PM exposure.
