The impact of pesticide residues on the gut microbiome and human health


Book Description

With a food safety focus, a scientific literature review was conducted to characterize the current understanding about the effects of pesticide residues on the human gut microbiome and potential implications on human health and non-communicable diseases (NCDs). The main aspects analysed are (1) effects of individual or combined pesticides on the composition, diversity and function of gut microbiome using in vivo or in vitro models; (2) health implications resulting from the pesticide-microbiome interactions and underlying mechanisms; (3) establishment of causality; and (4) influence of the gut microbiome on the metabolism and bioavailability of pesticides. The research was also scoped to identify current gaps, limitations and needs for the eventual consideration of microbiome-related data in chemical risk assessment. With this work, ESF contributes to the FAO global programme on the impact of food systems on NCDs and obesity, by understanding the potential health implications of gut microbiome-pesticide interactions. The outcomes will provide information which can be used to improve nutritional strategies and food safety policies.




The impact of veterinary drug residues on the gut microbiome and human health


Book Description

With a food safety focus, a scientific literature review was conducted to characterize the current understanding about the effects of veterinary drug residues on the human gut microbiome and potential implications on human health and non-communicable diseases (NCDs). The main aspects analysed are (1) effects of individual or combined drugs on the composition, diversity and function of gut microbiome using in vivo or in vitro models; (2) health implications resulting from the veterinary drug-microbiome interactions and underlying mechanisms; (3) establishment of causality; and (4) influence of the gut microbiome on the metabolism and bioavailability of veterinary drugs. The research was also scoped to identify current gaps, limitations and needs for the eventual consideration of microbiome-related data in chemical risk assessment. With this work, ESF contributes to the FAO global programme on the impact of food systems on NCDs and obesity, by understanding the potential health implications of gut microbiome-veterinary drug interactions. The outcomes will provide information which can be used to improve nutritional strategies and food safety policies.




Health Effects and Pesticide Perception as Determinants of Pesticide Use


Book Description

"In a recent survey of 820 Boro (winter rice), potato, bean, eggplant, cabbage, sugarcane, and mango farmers in Bangladesh, over 47 percent of farmers were found to be overusing pesticides. With only 4 percent of farmers formally trained in pesticide use or handling, and over 87 percent openly admitting to using little or no protective measures while applying pesticides, overuse is potentially a threatening problem to farmer health as well as the environment. To model pesticide overuse, the authors used a 3-equation, trivariate probit framework, with health effects and misperception of pesticide risk as endogenous dummy variables. Health effects (the first equation) were found to be strictly a function of the amount of pesticides used in production, while misperception of pesticide risk (the second equation) was determined by health impairments from pesticides and the toxicity of chemicals used. Pesticide overuse (the third equation) was significantly determined by variation in income, farm ownership, the toxicity of chemicals used, crop composition, and geographical location. The results highlight the necessity for policymakers to design effective and targeted outreach programs that deal specifically with pesticide risk, safe handling, and averting behavior. Ideally, the approach would be participatory in nature to address key informational gaps, as well as increasing a farmers' awareness retention. The results also point to specific crops and locations experiencing a higher prevalence of overuse-bean and eggplant in general-and overall production in the districts of Chapainawabganj, Chittagong, Comilla, Jessore, Narshingdi, Rajshahi, and Rangpur. Focusing efforts in these crop and geographical areas may have the most measurable effects on pesticide overuse. "--World Bank web site.




Plant Microbe Symbiosis: Fundamentals and Advances


Book Description

Plant microbe interaction is a complex relationship that can have various beneficial impacts on both the communities. An urgent need of today’s world is to get high crop yields in an ecofriendly manner. Utilization of beneficial and multifaceted plant growth promoting (PGP) microorganisms can solve the problem of getting enhanced yields without disturbing the ecosystem thus leading to sustainability. For this to achieve understanding of the intricate details of how the beneficial microbes form associations with the host plant and sustain that for millions of years must be known. A holistic approach is required wherein the diversity of microbes associated with plant and the network of mechanisms by which they benefit the host must be studied and utilized. ‘Plant Microbe Symbiosis – Fundamentals and Advances’ provides a comprehensive understanding of positive interactions that occur between plant and microorganisms and their utilization in the fields. The book reviews the enormous diversity of plant associated microbes, the dialog between plant-microbes-microbes and mechanisms of action of PGP microbes. Utilization of PGPRs as nutrient providers, in combating phytopathogens and ameliorating the stressed and polluted soils is also explained. Importantly, the book also throws light on the unanswered questions and future direction of research in the field. It illustrates how the basic knowledge can be amalgamated with advanced technology to design the future bioformulations.

Applied Soil Chemistry


Book Description

This book explores the state-of-the-art information regarding applied soil sciences. It covers the fundamentals, model concepts, principles, chemical reactions, functions, chemical recycling, chemical weathering, acid-base chemistry, carbon sequestration, and nutrient availability of soils. Also, it includes soil chemistry of heavy-metals, environment, clay, ion-exchange processes, analytical tools and applications. This book helps to understand the about soil characteristics targeting soil chemical reactions and interactions and its applications.




Pesticide Toxicity to Non-target Organisms


Book Description

The pesticide should cause effect on the target pests and be selective enough to spare the non-target beneficial. The book deals with the pesticide toxicity to predators, parasitoids and microbes which are used for pest management in the agroecosystem. The other beneficials exposed to pesticides are pollinators, earthworms, silkworm and fishes. The book contains information on the modes of pesticide exposure and toxicity to the organisms, sub-lethal effects of insecticides and method of toxicity assessment, risk assessment of pesticidal application in the field. The purpose of the work is to compile and present the different procedures to assess pesticide poising in organisms related to the agroecosystem along with discussions on risk assessment procedures with clear comparison of toxicity of pesticides to target pests and non target beneficial organisms.

Risk assessment of food allergens


Book Description

The Codex Committee on Food Labelling (CCFL) requested scientific advice as to whether certain foods and ingredients, such as highly refined foods and ingredients, that are derived from the list of foods known to cause hypersensitivity can be exempted from mandatory declaration. The objective of this fourth meeting was to expand on the recommendations from the first meeting concerning derivatives of food allergens and establish a framework for evaluating exemptions for food allergens. A pro forma process has been developed and tested against allergen derivatives previously granted exemptions in various countries or regions and found to be effective for consideration in future exemption decisions. The Expert Committee recommends that the process outlined in the pro forma process be used to guide any future development and evaluation of derivative exemptions. Establishment of safety based upon this weight of evidence approach is dependent upon consideration of data quality, outcome of the exposure assessment for all intended ingredient uses (specified for exemption) and review by competent authorities (as needed). When safety is established, exemption can be justified.
