To help children learn to avoid ingesting poisons, Mr. Yuk was conceived by Richard Moriarty, a pediatrician and clinical professor of pediatrics at the University of Pittsburgh School of Medicine who founded the Pittsburgh Poison Center and the National Poison Center Network. [1] Moriarty felt that the traditional skull and crossbones representing poison was no longer appropriate for children; Congressman Bill Coyne later said that by the 1970s the symbol was "associated with swashbuckling pirates and buccaneers rather than with harmful substances." [2]
The design and color were chosen when Moriarty used focus groups of young children to determine which combination was the most unappealing. Possible expressions were "mad" (crossed eyes and intense expression), "dead" (a sunken mouth and Xs for eyes), and "sick" (a sour expression with the tongue sticking out). [3] Children were asked to rank the faces according to which they liked the best, along with the skull and crossbones, and the "sick" face was least popular. [3] The shade of fluorescent green that was chosen was christened "Yucky!" by a young child and gave the design its name. [2]
In 1971 the Pittsburgh Poison Centre issued the Mr. Yuk sticker. Over the next few years, Mr. Yuk stickers were used nationwide to promote poison centres in the United States of America. [4] The stickers usually contained phone numbers of poison control centers that may give guidance if poisoning has occurred or is suspected. Usually, Mr. Yuk stickers carried the national toll-free number 1-800-222-1222. In some areas, local poison control centers and children's hospitals issue stickers with local numbers, under license.[ citation needed ] A public service announcement was also produced in 1971 featuring a theme song. [2]
At least two peer-reviewed medical studies (Fergusson 1982, Vernberg 1984) have suggested that Mr. Yuk stickers do not effectively keep children away from potential poisons and may even attract children. [5] Specifically, Vernberg and colleagues note concerns for using the stickers to protect young children. Fergusson and colleagues state that "the method may be effective with older children or as an adjunct to an integrated poisoning prevention campaign". [6]
To evaluate the effectiveness of six projected symbols (skull-and-crossbones, red stop sign, and four others), tests were conducted at day care centers. Children in the program rated Mr. Yuk as the most unappealing image. By contrast, children rated the skull-and-crossbones to be the most appealing. [7]
Mr. Yuk and his graphic rendering are registered trademarks and service marks of the UPMC Children's Hospital of Pittsburgh, and the rendering itself is additionally protected by copyright. [8] The Children's Hospital of Pittsburgh of UPMC gives out free sheets of Mr. Yuk stickers if contacted by mail. [9]
Given the evidence regarding the campaign's effectiveness, some poison control centers no longer distribute Mr. Yuk stickers. [10] However, as of May 2024, other poison control centers, such as the Pittsburgh Poison Center continue to offer stickers. [11]
A poison is any chemical substance that is harmful or lethal to living organisms. The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense.
A skull and crossbones is a symbol consisting of a human skull and two long bones crossed together under or behind the skull. The design originated in the Late Middle Ages as a symbol of death and especially as a memento mori on tombstones.
Syrup of ipecac, or simply ipecac, is a drug that was once widely used as an expectorant and a rapid-acting emetic. It is obtained from the dried rhizome and roots of the ipecacuanha plant, from which it derives its name. It is no longer regularly used in medicine.
Hazard symbols or warning symbols are recognisable symbols designed to warn about hazardous or dangerous materials, locations, or objects, including electromagnetic fields, electric currents; harsh, toxic or unstable chemicals ; and radioactivity. The use of hazard symbols is often regulated by law and directed by standards organizations. Hazard symbols may appear with different colors, backgrounds, borders, and supplemental information in order to specify the type of hazard and the level of threat. Warning symbols are used in many places in place of or in addition to written warnings as they are quickly recognized and more universally understood, as the same symbol can be recognized as having the same meaning to speakers of different languages.
Malathion is an organophosphate insecticide which acts as an acetylcholinesterase inhibitor. In the USSR, it was known as carbophos, in New Zealand and Australia as maldison and in South Africa as mercaptothion.
Chemical hazards are hazards present in hazardous chemicals and hazardous materials. Exposure to certain chemicals can cause acute or long-term adverse health effects. Chemical hazards are usually classified separately from biological hazards (biohazards). Chemical hazards are classified into groups that include asphyxiants, corrosives, irritants, sensitizers, carcinogens, mutagens, teratogens, reactants, and flammables. In the workplace, exposure to chemical hazards is a type of occupational hazard. The use of personal protective equipment may substantially reduce the risk of adverse health effects from contact with hazardous materials.
A poison control center is a medical service that is able to provide immediate, free, and expert treatment advice and assistance over the telephone in case of exposure to poisonous or hazardous substances. Poison control centers answer questions about potential poisons in addition to providing treatment management advice about household products, medicines, pesticides, plants, bites and stings, food poisoning, and fumes. In the US, more than 72% of poison exposure cases are managed by phone, greatly reducing the need for costly emergency department and doctor visits.

The 1971 Iraq poison grain disaster was a mass methylmercury poisoning incident that began in late 1971. Grain treated with a methylmercury fungicide and never intended for human consumption was imported into Iraq as seed grain from Mexico and the United States. Due to a number of factors, including foreign-language labelling and late distribution within the growing cycle, this toxic grain was consumed as food by Iraqi residents in rural areas. People suffered from paresthesia, ataxia and vision loss, symptoms similar to those seen when Minamata disease affected Japan. The recorded death toll was 459 people, but figures at least ten times greater have been suggested. The 1971 poisoning was the largest mercury poisoning disaster when it occurred, with cases peaking in January and February 1972 and stopping by the end of March.
Medical toxicology is a subspecialty of medicine focusing on toxicology and providing the diagnosis, management, and prevention of poisoning and other adverse effects due to medications, occupational and environmental toxicants, and biological agents. Medical toxicologists are involved in the assessment and treatment of a wide variety of problems, including acute or chronic poisoning, adverse drug reactions (ADRs), drug overdoses, envenomations, substance abuse, industrial accidents, and other chemical exposures.

Mr. Ouch is a hazard symbol developed by the US’s National Electrical Manufacturers Association (NEMA) to represent electrical hazard within pad-mounted transformers. Unlike other high-voltage warning symbols, Mr. Ouch was specifically designed with young children in mind. It is part of NEMA Standard 260-1996, Safety Labels for Pad-Mounted Switchgear and Transformers Sited in Public Areas, which lays out design guidelines for a complete label design that incorporates the Mr. Ouch symbol.
Poisoning is the harmful effect which occurs when toxic substances are introduced into the body. The term "poisoning" is a derivative of poison, a term describing any chemical substance that may harm or kill a living organism upon ingestion. Poisoning can be brought on by swallowing, inhaling, injecting or absorbing toxins through the skin. Toxicology is the practice and study of symptoms, mechanisms, diagnoses, and treatments correlated to poisoning.
Like most detergent products, Tide Pods, a laundry detergent pod sold by Procter & Gamble (P&G) since 2012, can be deadly if ingested. Media reports have discussed how children and those with dementia could mistake laundry pods for candy and endanger their health or life by consuming them, and they were named an emerging health risk by the Centers for Disease Control and Prevention in 2012. Between 2012 and 2013, poison control centers reported over 7,000 cases of young children eating laundry pods, and ingestion of laundry pods produced by P&G had resulted in six deaths by 2017. In response to the dangers, P&G changed Tide Pod containers to an opaque design, introduced warning labels, and added a bitter-tasting chemical to the pod contents.
