Food Hygiene

Amir Mokhtari, Jane M Van Doren
We used an agent-based modeling (ABM) framework and developed a mathematical model to explain the complex dynamics of microbial persistence and spread within a food facility and to aid risk managers in identifying effective mitigation options. The model explicitly considered personal hygiene practices by food handlers as well as their activities and simulated a spatially explicit dynamic system representing complex interaction patterns among food handlers, facility environment, and foods. To demonstrate the utility of the model in a decision-making context, we created a hypothetical case study and used it to compare different risk mitigation strategies for reducing contamination and spread of Listeria monocytogenes in a food facility...

Child mortality is a major public health problem in Sub-Saharan Africa and is influenced by nutritional status. A conceptual framework were proposed to explain factors related to under nutrition. Previously proposed conceptual frameworks for under nutrition do not consider child mortality and describe factors related to under nutrition from a qualitative viewpoint only. A structural equation modelling approach was applied to the data from World Bank and FAO databases collected from over 37 Sub-Saharan Countries from 2000 to the most recent update...

Clean water is vital for life; it is required not only for drinking but also for the preparation of food and proper hygiene. Unfortunately, more than fifty percent of the world population mainly in China and India face a severe scarcity of water. Around 1.8 billion people inevitably drink water from sources having fecal contamination resulting in the death of about a million children every year. Scientists are developing various economic technologies to decontaminate and purify water. Nanomaterials-based technology offers an economic and effective alternative for water purification and decontamination...

Effective monitoring of microbial pathogens is essential for a successful preventive food safety and hygiene strategy. However, as most monitoring strategies are growth-based, these tests fail to detect pathogenic bacteria that have entered the viable but non-culturable (VBNC) state. The present study reports the induction of the VBNC state in five human pathogens by commercially available household cleaners in combination with inorganic salts. We determined that non-ionic surfactants, a common ingredient in household cleaners, can induce the VBNC state, when combined with salts...

BACKGROUND: Persistently high maternal mortality levels are a concern in developing countries. In India, monetary incentive schemes have increased institutional delivery rates appreciably, but have not been equally successful in reducing maternal mortality. Maternal outcomes are affected by quality of obstetric care and socio-cultural norms. In this light there is need to examine the quality of care provided to women delivering in institutions. OBJECTIVE: This study aimed to examine pregnant women's expectations of high-quality care in public health facilities in Uttar Pradesh, India, and to contrast this with provider's perceptions of the same, as well as the barriers that limit their ability to provide high-quality care...

We aimed to better understand resistome and virulome patterns on animal and process-area surfaces through a pig slaughterhouse to track possible contamination within the food production chain. Culture-dependent methods revealed high levels of microbial contamination, corresponding to mesophilic and pathogenic bacteria on both the animal and process-area surfaces mainly in the anesthesia (AA and AS) zone followed by "scorching and whip" (FA and FS) zone and also in the end products. To evaluate the potential risk of antibiotic resistance and virulence determinants, shotgun metagenomic DNA-sequencing of isolates from selected areas/products uncovered a high diversity and richness of antibiotic resistance genes (ARGs): 55-62 genes in the anesthesia area (AA and AS) and 35-40 in "animal-arrival zone" (MA and MS)...

Efforts to prevent foodborne illnesses in food facilities require sufficient knowledge on hygiene and safety standards from both food processors and customers. However, studies about knowledge, attitude, and practices of customers towards these issues are constrained. This study explored the knowledge, attitude, and practices (KAP) of customers regarding the practices of food facilities as well as potential associated factors. A cross-sectional survey was conducted in Hanoi from September to October 2015. Questions about knowledge, attitude, and practice towards food hygiene and safety were asked, alongside sociodemographic characteristics...

This review appraises over 150 recent original papers reporting data that demonstrate the greatly reduced tyramine content of modern-day 'foods', about which the medical literature has a paucity of information. It discusses the cardiovascular pharmacology of tyramine and the characteristics, extent, risks, and treatment of the blood pressure increases that sometimes result from tyramine ingestion (the pressor response). In past decades, cheese was the only food associated with documented fatalities resulting from hypertension...
