Biocides are added to many consumer goods such as cosmetics and detergents to kill bacteria or inhibit their growth. They include disinfectants, preservatives as well as antiseptics and are widely used in animal husbandry, food production and health care.
There is concern that this widespread use of biocides may lead to the emergence or proliferation of harmful bacteria that are resistant to both biocides and antibiotics.
In the light of current scientific evidence, can biocides lead to antibiotic resistant bacteria?
This document discusses biocides, which are formulations containing active substances that control or destroy harmful organisms. It provides background information on biocides, including types (chemical and natural), major classes, and common active ingredients. The document outlines both arguments for biocides, such as increased food supply and farmer profits, and risks, like negative health and environmental impacts. It also describes common applications of biocides in areas like agriculture, swimming pools, cosmetics/pharmaceuticals, and medical device sterilization. In conclusion, the document states that biocide use should be minimized and carefully regulated due to the risks involved.
The document discusses the current regulations for pesticide use in farming and whether they are sufficient for healthy living. It provides information on what pesticides are, the EPA regulations, types of pesticides and their effects, advantages and disadvantages of pesticide use, potential health effects, benefits of organic foods, and advances in technology that could reduce pesticide use. While pesticides improve food production and quality of life, the EPA approval process is slow and pesticides can damage the environment and health, especially for sensitive groups. More research into alternatives is still needed to establish effective regulations that protect both public health and agriculture.
There are four main problems caused by pesticides: super bugs that have evolved resistance, persistent pesticides that don't break down easily, bioaccumulation of pesticides in tissues up the food chain, and pesticides eliminating both pests and beneficial insects. A better approach is integrated pest management which uses multiple control methods like resistant plant varieties, beneficial insects, microbial pesticides, insect sterilization, biochemical pesticides, cultivation timing, and small amounts of synthetic pesticides to reduce pest populations while minimizing pesticide use. Integrated pest management has seven parts to its program.
This document discusses pesticide residues in food. It begins by defining pesticides and explaining how residues can occur in foods when pesticides are used during agricultural production.

Natural pesticides & herbicides by pooja khanparaPOOJA KHANPARA
The document discusses the mechanisms of action for different types of pesticides. It explains that stomach poisons kill pests by being ingested and absorbed in the blood, while contact insecticides kill on direct or indirect contact by penetrating the body. Fumigants can be applied in enclosed areas to surround and enter the breathing pores of insects. It also compares contact and systemic fungicides, noting that contact fungicides act preventatively at the application site while systemic fungicides can be absorbed and act both preventatively and curatively throughout the plant. Resistance is a greater risk for systemic fungicides which have a single site of action.
Most chemical insecticides act by poisoning the nervous system and while they can kill target insects and pests, they may also harm other non-pest species like wildlife and humans. Insecticides come in many types including systemic insecticides which are absorbed by plant tissues and fumigants which are insecticidal gases. While pesticides are used to control pests that can damage property or spread disease, they also have potential drawbacks like toxicity to humans and environmental effects. Common types of pesticides include insecticides, herbicides, fungicides, and rodenticides, which are employed using various application methods and equipment depending on the target pest.

Biopesticides are naturally occurring substances from certain plants, animals, bacteria, and minerals that control pests through non-toxic mechanisms. They include microbial pesticides from organisms like Bacillus thuringiensis (Bt) and fungal pesticides like Beauveria bassiana. Biochemical pesticides also interfere with insect mating through sex pheromones. While biopesticides are less toxic than chemical pesticides, they also have drawbacks like being less persistent and requiring specialized application knowledge. When used as part of integrated pest management, biopesticides can greatly reduce reliance on conventional pesticides while maintaining crop yields.
Water Disinfectants & disinfectant by-productsGreenFacts
To protect drinking water against germs and fight disease transmitted through water, disinfectants such as chlorine, chloramines, ozone and chlorine dioxide are used. These disinfectants can react with natural material in the water to form certain unwanted by-products, which raise health concerns.
Bio-fertilizers are cost effective and environmentally friendly alternatives to chemical fertilizers. They contain living microorganisms that help plants uptake nutrients through interactions in the soil. Bio-fertilizers make nutrients more available, promote root and plant growth, improve soil health and crop yields, and have residual benefits. They can help reduce reliance on expensive chemical fertilizers. Bio-pesticides are living organisms used to control pests and are generally less toxic than conventional pesticides by mainly affecting only the target pests. Genetically modified foods are derived from organisms modified through genetic engineering techniques to introduce specific DNA changes and can include crops designed for human consumption with altered nutritional properties or the ability to produce vaccines or pharmaceuticals.

This document discusses the role of antibiotics in animal feed and the development of antibiotic resistance. It notes that antibiotic resistance first emerged as an intrinsic property in some bacteria and later developed through selective pressure from antibiotic exposure. The routine use of antibiotics as growth promoters in food animals is identified as a serious public health issue as it can create a reservoir of resistant bacteria that spread to humans. The document argues that antibiotics should not be used as growth promoters and only be used prudently for therapy and prophylaxis to minimize resistance. Adopting principles like restricting antibiotics critical for human medicine and minimizing prophylactic use could substantially reduce unnecessary antibiotic resistance.
The document discusses the production of antibiotics and antitumor agents through industrial microbiology. It defines antibiotics as substances produced by microorganisms that inhibit or kill other microorganisms. Antibiotics are produced through the fermentation of microorganisms like Streptomyces. The production process involves growing the culture in large tanks, isolating the antibiotic, and purifying it into final products through various chemical processes. Quality control ensures antibiotics meet standards before distribution. Some antibiotics like anthracyclines also have antitumor properties and are used to treat cancer.

Bisphenol A (BPA) is used to produce certain plastics and medical devices. While BPA is efficiently metabolized when ingested, its metabolism is less efficient when exposure comes from medical devices. There is debate about the health risks of BPA exposure from food and medical devices, with some studies finding specific effects from low doses but no clear conclusions. Certain medical procedures that result in prolonged exposure, like those for neonates and dialysis patients, may pose a risk since exposure could exceed the tolerable daily intake level. More information is needed on alternatives to BPA in medical devices to properly evaluate risks versus treatment benefits.
Este documento discute los riesgos potenciales para la salud de la exposición al bisfenol A (BPA) a través de dispositivos médicos. Existe un debate sobre si el nivel actual de exposición al BPA representa un riesgo, aunque algunos estudios muestran efectos potenciales a dosis bajas. La exposición al BPA a través de dispositivos médicos como catéteres es menor que a través de alimentos, pero puede superar los niveles considerados seguros en algunos casos como en unidades de cuidados intens

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
