![]() ![]() Pesticides are potentially toxic to humans and can have both acute and chronic health effects, depending on the quantity and ways in which a person is exposed.Pesticides are used to protect crops against insects, weeds, fungi and other pests.To protect food consumers from the adverse effects of pesticides WHO reviews evidence and develops internationally-accepted maximum residue limits.This is particularly important in countries that face food shortages. They protect or increase yields and may increase the number of times each year a crop can be grown on the same land. ![]() Pesticides play a significant role in food production.Many of these chemicals have been banned from agricultural use in developed countries, but they are still used in many developing countries. Some of the older, less costly pesticides can remain for years in soil and water.EPA has the authority to issue emergency exemptions for pesticides for use in anthrax spore decontamination efforts. Anthraxīiological agents such as Bacillus anthracis spores can cause a threat to public health and national security. In 2004, EPA determined that prions are considered to be a pest under FIFRA (PDF), and that products used to control prions are subject to EPA regulation. PrionsĬertain proteins found in cells of the central nervous system of humans and animals may exist in abnormal, infectious forms called "prions." Prions share many characteristics of viruses, and may cause fatal diseases. ![]() These products are typically used by the poultry industry to disinfect their facilities. EPA works to register and make available antimicrobial pesticide products (sanitizers or disinfectants) that may be used to kill avian influenza virus on inanimate surfaces and to help prevent the spread of avian flu viruses. Infections with these viruses can occur in humans, but the risk is generally low for most people. Avian FluĪvian flu, sometimes called bird flu, is an infection that occurs naturally and chiefly in birds. EPA registers antimicrobial products intended to control these microorganisms and help prevent the spread of numerous diseases. Various microorganisms, including bacteria, viruses, and protozoans, can cause microbial contamination in hospitals, public health clinics, and food processing facilities. In addition to registering products to control these pests, EPA also provides information to the public about safely using these products in homes and schools. Indoor household pests such as cockroaches can contribute to asthma and allergies. View information about transmission of the Zika virus in the United States and other locations. ![]() EPA registers several pesticide products, including repellents, that may be used to control the vectors that spread these diseases. Infectious diseases such as West Nile virus, Lyme disease, and rabies can be carried and spread by vector (disease-carrying) species such as mosquitoes, ticks, and rodents. Significant Public Health Problems that are Caused by Pests Vector-Borne Diseases Wood Preservatives to make wood resistant to insects, fungus and other pests.Rodenticides to kills rodents like mice, rats, and gophers.Insect Growth Regulators to disrupt the growth and reproduction of insects.Herbicides to kill or inhibit the growth of unwanted plants, also known as weeds.Fungicides to control fungal problems like molds, mildew, and rust.Disinfectants to control germs and microbes such as bacteria and viruses.Antimicrobials to control germs and microbes such as bacteria and viruses.Algaecides to kill and/or slowing the growth of algae.There are many different types of pesticides each is meant to be effective against specific pests. Pesticides are used in agriculture to control weeds, insect infestation and diseases. Pesticides are used to control various pests and disease carriers, such as mosquitoes, ticks, rats and mice. ![]()
