Timeline of the 2008 Chinese milk scandal

Last updated

This timeline of the 2008 Chinese milk scandal documents how events related to the Chinese dairy products contamination by melamine unfolded. Complaints about kidney problems traced back to a brand of infant formula, subsequent discoveries of melamine contamination of liquid milk, and exported powdered milk of processed food products (using contaminated milk). The scandal decimated Chinese dairy exports, and re-exposed long-standing concerns about food security, corruption, lack of political checks and balances. Though the scandal came to attention in 2008, its roots can be traced back to events prior to 2008.

Melamine Chemical compound

Melamine is an organic compound with the formula C3H6N6. This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred. Melamine can be combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards. Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.

Fonterra New Zealand dairy co-operative

Fonterra Co-operative Group Limited is a New Zealand multinational publicly traded dairy co-operative owned by around 10,500 New Zealand farmers.

Powdered milk Dehydrated milk product

Powdered milk, also called milk powder, dried milk, or dry milk, is a manufactured dairy product made by evaporating milk to dryness. One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content. Another purpose is to reduce its bulk for the economy of transportation. Powdered milk and dairy products include such items as dry whole milk, nonfat (skimmed) dry milk, dry buttermilk, dry whey products and dry dairy blends. Many exported dairy products conform to standards laid out in Codex Alimentarius.

Beginning in March 2007, there was a widespread recall of many brands of cat and dog foods due to contamination with melamine and cyanuric acid. The recalls in North America, Europe, and South Africa came in response to reports of kidney failure in pets. Initially, the recalls were associated with the consumption of mostly wet pet foods made with wheat gluten from a single Chinese company. After more than three weeks of complaints from consumers, the recall began voluntarily with the Canadian company Menu Foods on 16 March 2007, when a company test showed sickness and death in some of the test animals. Soon after, there were numerous media reports of animal deaths as a result of kidney failure. In the following weeks, several other companies who received the contaminated wheat gluten also voluntarily recalled dozens of pet food brands. One month after the initial recall, contaminated rice protein from a different source in China was also identified as being associated with kidney failure in pets in the United States, while contaminated corn gluten was associated with kidney failure with pets in South Africa. As a result of investigating the 2007 pet food recalls, a broader Chinese protein export contamination investigation unfolded, raising concerns about the safety of the human food supply.

This timeline of the 2007 pet food recalls documents how events related to the 2007 pet food recalls unfolded. Several contaminated Chinese vegetable proteins were used by pet food makers in North America, Europe and South Africa, leading to kidney failure in animals fed the contaminated food. Both the centralization of the pet food industry and the speed and manner of the industry and government response became the subjects of critical discussion.

In China, the adulteration and contamination of several food and feed ingredients with inexpensive melamine and other compounds, such as cyanuric acid, ammeline and ammelide, are common practice. These adulterants can be used to inflate the apparent protein content of products, so that inexpensive ingredients can pass for more expensive, concentrated proteins. Melamine by itself has not been thought to be very toxic to animals or humans except possibly in very high concentrations, but the combination of melamine and cyanuric acid has been implicated in kidney failure. Reports that cyanuric acid may be an independently and potentially widely used adulterant in China have heightened concerns for both animal and human health.

In 2007 a series of product recalls and import bans were imposed by the product safety institutions of the United States, Canada, the European Union, Australia and New Zealand against products manufactured in and exported from the mainland of the People's Republic of China (PRC) because of numerous alleged consumer safety issues. The many product recalls within the year led Consumer Reports and other observers to dub 2007 "The Year of the Recall.”

2008 Chinese milk scandal Food safety crisis

The 2008 Chinese milk scandal was a significant food safety incident in China. The scandal involved milk and infant formula along with other food materials and components being adulterated with melamine. The chemical was used to increase the nitrogen content of diluted milk, giving it the appearance of higher protein content in order to pass quality control testing. Of an estimated 294,000 victims, 6 babies died from kidney stones and other kidney damage and an estimated 54,000 were hospitalized.

Food safety incidents in China

Food safety incidents in China have received increased international media scrutiny following the reform and opening of the country, and its joining the World Trade Organization. Urban areas have become more aware of food safety as their incomes rise. Food safety agencies in China have overlapping duties. The 2008 Chinese milk scandal and COVID-19 pandemic received the most attention among food safety incidents.

In 2013 a wide-scale recall of products sold by dairy producer Fonterra was announced after suspected botulism-causing bacteria were found during safety tests. The contaminated whey products had been sold to third parties who use it to produce infant formula and sports drinks. Approximately 1,000 tonnes of consumer product was affected by the recall across seven countries, but no cases of sickened consumers were reported. China, which imports most of its powdered milk from New Zealand, instituted a temporary ban on the import of the ingredient from New Zealand.
