List of food contamination incidents
In contrast to microbiologically caused foodborne illness, the link between exposure and effect of chemical hazards in foods is usually complicated by cumulative low doses and the delay between exposure and the onset of symptoms. Chemical hazards include environmental contaminants, food ingredients (such as iodine), heavy metals, mycotoxins, natural toxins, improper storage, processing contaminants, and veterinary medicines.
Incidents have occurred because of poor harvesting or storage of grain, use of banned veterinary products, industrial discharges, human error and deliberate adulteration and fraud.
Definition of an incident
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain, and traced back to a particular event.
Information on the impacts of these incidents is fragmentary and unsystematic, ranging from thousands of dollars to meet the cost of monitoring analysis, to many millions of dollars due to court prosecutions, bankruptcy, product disposal, compensation for revenue loss, damage to brand or reputation, or loss of life.
List of notable incidents
- Roman Empire – There is speculation that the Romans, in particular the elite, suffered chronic to severe lead poisoning due to the ubiquity of this metal in e.g. lined pots in which acidic foodstuffs were boiled, over and above any mere exposure to lead in water pipes. They also used sugar of lead to sweeten their wines.
- Europe - numerous incidents of human poisoning due to the consumption of rye bread made from grain infected with ergot fungi
- 1850s - Swill milk scandal in New York
- 1857 – adulteration of bread with alum in London, causing rickets
- 1857 - poisoning of bread with arsenic in Hong Kong targeting the colonial community.
- 1858 – sweets poisoned with arsenic in Bradford, England.
1900 to 1949
- 1900 – Beer contaminated with arsenic. Traced to sugar manufactured with sulphuric acid that was naturally contaminated with arsenic from Spanish pyrites. An epidemic of 6070 cases in London, including 70 deaths
- 1910–45 – Cadmium from mining waste contaminated rice irrigation water in Japan. Illness known as Itai-itai disease affected more than 20% of women aged over 50 years
- 1920 – In South Africa, 80 people suffered poisoning from eating bread contaminated with naturally occurring pyrrolizidine alkaloids.
- 1900–47 – Severe and widespread neurological disorders due to bleaching of bread flour with the agene process for bleaching of flour with nitrogen chloride, a process no longer in use. The denatured protein in the treated flour is toxic and causes a condition of hysteria in dogs eating biscuits made from the flour.
- 1930s – A striking example of OPIDN Organophosphate poisoning occurred during the 1930s Prohibition Era when thousands of men in the American South and Midwest developed arm and leg weakness and pain after drinking a "medicinal" alcohol substitute. The drink, called "Ginger Jake," contained an adulterated Jamaican ginger extract containing tri-ortho-cresyl phosphate (TOCP) which resulted in partially reversible neurologic damage. The damage resulted in the limping "Jake Leg" or "Jake Walk" which were terms frequently used in the blues music of the period. Europe and Morocco both experienced outbreaks of TOCP poisoning from contaminated abortifacients and cooking oil, respectively.
1950 to 2000
- 1951 - 1951 Pont-Saint-Esprit mass poisoning in France, probably caused by Ergot.
- 1950s – Mercury poisoning in fish in Japan, contaminated by industrial discharge: Minamata disease. By 2010 more than 14,000 victims had received financial compensation.
- 1955 – Arsenic in milk powder in Japan. Disodium phosphate additive was inadvertently contaminated with sodium arsenate. The incident was known as the "Moringa dried milk poisoning". By 2002 there were an estimated 13,400 cases and over 100 deaths attributed to consumption of the milk powder.
- 1957 – Chicken feed and thence chickens were contaminated with dioxins from polychlorinated treated cow hides in the United States. 300,000 chickens were killed or destroyed to avoid consumption
- 1959 – Moroccan oil poisoning disaster: several thousand people in the city of Meknes suffer flaccid paralysis caused by deliberate contamination of cooking oil with jet engine lubricating oil containing tricresyl phosphate obtained as surplus from a US airbase at Nouaceur.
- 1965 - mass poisoning resulting from contamination of flour with 4,4'-Methylenedianiline in Epping, Essex, United Kingdom
- 1968 - Yushō disease; mass poisoning resulting from contamination of rice bran oil with PCBs in Kyūshū, Japan
- 1972 – mercury poisoning in Iraq kills 100 to 400 as seeds treated with mercury as a fungicide that are meant for planting are used as food "Informed travelers from Baghdad say Iraq is in the grip of a severe mercury-poisoning outbreak. The travelers, who arrived last night, reported that 100 to 400 people had died since the outbreak began early in February."

- 1976 – Seveso dioxin contamination in Italy.
- 1981 – Spanish Toxic Oil Syndrome. Thousands permanently damaged due to eating industrial colza oil denatured with aniline sold as olive oil.

- 1986 – Adulteration of Italian wines with ethylene glycol killed more than 18 people
- 1987 – Beech-Nut Nutrition Corporation paid $2.2 million, then the largest fine issued, for violating the Federal Food, Drug, and Cosmetic Act by selling artificially flavored sugar water as apple juice. John F. Lavery, the company's vice president for operations was convicted in criminal court and sentenced to a year and a day in jail; Niels L. Hoyvald, the president of the company, also convicted, served six months of community service. Each of them also paid a $100,000 fine
- 1989 – Milk contamination with dioxin in Belgium
- 1994 – Ground paprika in Hungary was found to be adulterated with lead oxide, causing deaths of several people, while dozens of others became sick.
- 1998 – In New Delhi, India adulteration of edible mustard oil with Argemone mexicana seed oil caused epidemic dropsy in thousands of people. Epidemic dropsy is a clinical state resulting from consumption of edible oils adulterated with Argemone mexicana seed oil that contains the toxic alkaloids sanguinarine and dihydrosanguinarine. The epidemic in 1998 at New Delhi is the largest so far, in which over 60 persons lost their lives and more than 3000 victims were hospitalized.Even after that the epidemics occurred at alarming frequency at Gwalior (2000), Kannauj (2002) and Lucknow (2005) cities of India.

An industry source in Rome said he doubts that any of the polluted wine has reached the United States. The Italian Wine and Food Institute, which represents Italian wine exporters in New York, was quoted here as saying that all Italian wine shipped to the United States is subjected to strict quality control in order to win the Italian government's seal of approval. Italy ships more wine to the United States than any other wine-producing nation, but most of its wine exports go to France and Germany, in that order, much of it in bulk for use in cutting domestic wines with higher-alcohol Italian varieties. It is far worse in scale than the scandal that virtually eliminated Austrian wines from the market last year. Some Austrian wine makers were found to have added ethylene glycol, a toxic, sweetening element, to their wines, and the discovery wiped out export sales. Ethylene glycol is also used in antifreeze. There were no known fatalities from the tainted Austrian wine.

It is well within the reach of most white-collar criminals to assume an air of irreproachable virtue, especially when they're about to be sentenced. But there was something unusually compelling about the bearing of Niels L. Hoyvald and John F. Lavery as they stood before Judge Thomas C. Platt of the United States District Court in Brooklyn last month – especially in light of what they were being sentenced for. As president and vice president of the Beech-Nut Nutrition Corporation, Hoyvald and Lavery had sold millions of bottles of apple juice that they knew to contain little or no apple juice at all – only sugars, water, flavoring and coloring. The consumers of this bogus product were babies.
