Since 2010, rumours have circulated, particularly on social media, that rice sold in Africa and elsewhere is made of plastic. These rumours were fuelled by viral videos showing people bouncing rice balls and claiming that they were made of plastic. Despite food safety agencies' inability to find evidence supporting these claims, some consumers remain concerned about the possibility of consuming plastic rice. This has led to the development of various tests to identify potential plastic rice contamination, such as the water test, microwave test, and hot oil test. While these tests may provide some reassurance, it's important to note that plastic rice is not a widespread issue, and there is little evidence supporting its existence.

Plastic rice myths and social media
Rumours of plastic rice being sold in Africa and other parts of the world have been circulating on social media since around 2010, driven by viral videos showing bouncing rice balls. Despite little evidence that it's a widespread problem, the rumours have persisted, fuelled by concerns about food safety and distrust of foreign imports.
The rumours of plastic rice originated in China, with reports of plastic rice being manufactured and mixed with real rice to deceive consumers. In 2016, Nigerian customs authorities seized 2.5 tonnes of rice, initially claiming it was made of plastic. However, these claims were later refuted by the country's health minister, who stated there was no evidence to support the allegations. The rice was found to contain high levels of bacteria, but it was not made of plastic.
The persistence of the plastic rice rumours has led to investigations by food safety authorities and governments in various countries, including Ghana, Nigeria, and Somaliland. These investigations have consistently found no evidence of plastic rice being sold or consumed in their respective markets. Despite this, the rumours continue to spread, with recent reports of plastic rice in Somaliland creating a wave of media coverage.
While there may be no truth to the claims of plastic rice, the rumours have had a significant impact. They have caused public panic, sparked investigations, and even influenced consumer behaviour, with some people choosing to avoid imported rice in favour of locally grown options. The spread of misinformation on social media has been identified as a powerful tool for creating chaos and pursuing political agendas.
To address the concerns, food safety experts have provided methods to identify potential plastic rice. These include conducting water, microwave, stovetop, hot oil, and fungus tests. However, it's important to note that these tests may not be entirely reliable, and the most effective way to debunk the myth is through scientific investigations and official statements from food safety authorities and governments.

Testing methods for plastic rice
Although there is little evidence that plastic rice is a widespread problem, there are several methods to test for its presence. Here are some of the testing methods for plastic rice:
Water Test
This involves adding rice to a bowl of water and observing whether it sinks or floats. Real rice will sink to the bottom due to its density, while plastic rice will float to the surface. Although some dirt or debris may float, all rice grains should sink.
Microwave Test
This test involves combining equal parts rice and water in a microwave-safe bowl and microwaving it on high for 3 to 5 minutes. After microwaving, use a spoon to skim the surface and check for a layer of plastic residue. Plastic rice will form a thick layer of melted plastic, while real rice will fluff up and absorb the water.
Stovetop Boiling Test
Similar to the microwave test, this method involves boiling rice and water on a stovetop for about 10 minutes. After boiling, check for plastic residue on the surface. Real rice may have some starchy residue, but it will be noticeably different from a thick layer of melted plastic.
Hot Oil Test
For this test, coat a pan with a tablespoon of oil and heat it on high. Once the oil is very thin and hot, add a thin layer of rice. Observe the grains for any contraction or melting, as plastic will melt when exposed to high heat.
Fungus Test
This test involves boiling rice for 10 minutes, then transferring it to a plastic bottle or container and letting it sit for 2 to 3 days. If the rice does not develop any mould or fungus, it could indicate the presence of plastic.
Fire Test
This test involves scooping rice with a tablespoon and carefully burning it with a lighter to observe any changes that may indicate the presence of plastic.
Chemical Solvent Tests
Certain chemical solvents can be used to test for plastic rice. For example, putting rice in a test tube of alcohol, such as ethanol or isopropanol, should cause the rice to swell if it is made of polyurethane. Similarly, using acetone as a solvent will partially dissolve and decrease the size of polyurethane rice grains. However, these tests may be challenging to perform and require caution due to the potential dangers of chemical solvents.

Plastic rice in Africa
Rumours of plastic rice being sold in Africa have been circulating on social media since 2016, with viral videos showing people bouncing rice balls. In 2016, Nigerian customs authorities confiscated 2.5 tonnes of rice that they claimed was plastic. However, they later backtracked when the country's health minister said there was no evidence for these claims. Tests showed that the rice contained a high level of bacteria, but no plastic.
In 2017, rumours spread in Senegal, The Gambia, and Ghana, prompting the Ghana Food and Drugs Authority to investigate. They invited consumers and traders to submit samples of any rice brands they suspected of being made of plastic and concluded that there was no plastic rice being sold on the Ghanaian market.
Despite little evidence that it's a widespread problem, rumours of plastic rice continue to circulate, fuelled by videos purporting to show how the rice is made in factories. Some journalists have speculated that the rumours are driven by protectionism and distrust of foreign imports, particularly in countries highly dependent on imported rice, such as Ivory Coast and Senegal.
Food safety authorities in West Africa have been addressing the rumours head-on, with governments compelled to make statements denying the presence of plastic rice. While there is no evidence of large amounts of plastic chips being passed off as rice, the public is advised to exercise caution when consuming rice. Tests to identify potential plastic rice include the water test, the microwave test, the stovetop boil test, the hot oil test, and the fungus test.

Plastic rice in China
Rumours of plastic rice being sold in Africa and elsewhere have been circulating on social media since about 2010. These rumours were originally prompted by "fake rice" scandals in China, although they didn't involve food made entirely out of plastic. In 2016, Nigerian customs authorities confiscated 2.5 tonnes of rice, initially claimed to be plastic, but later found to be real rice with a high level of bacteria. Despite little evidence that it's a widespread problem, rumours of plastic rice persist, fuelled by viral videos showing bouncing rice balls and people making rice balls out of supposedly plastic rice. Some videos also purport to show how the rice is made in factories.
The rumours have led to concerns about the safety of imported rice, particularly in countries dependent on imports such as Ivory Coast and Senegal. In response, food safety authorities in West Africa have addressed the rumours head-on, with the Ghana Food and Drugs Authority inviting consumers and traders to submit samples of any rice brands they suspected of being made of plastic. Their investigation concluded that there was no plastic rice being sold on the Ghanaian market.
While there have been no confirmed cases of large amounts of plastic rice being passed off as real rice, "plastic rice" does exist. It is manufactured for use in shipping boxes and is likely more expensive than real rice. However, fake rice made from other materials does exist in Japan, China, and Thailand, where it is used as a display item for restaurants and is not intended for consumption.
To identify plastic rice, you can perform a water test by submerging the rice in water and stirring it for a few seconds. Real rice will sink to the bottom due to its density, while plastic rice will float. You can also try microwaving the rice on high for 3-5 minutes and skimming the surface with a spoon to check for a layer of plastic residue. Alternatively, you can boil the rice or add it to a hot pan of oil to check for grains that contract and melt, as plastic melts when exposed to high heat.

Food safety authorities' response
Since as early as 2010, rumours have been circulating—particularly on social media—that rice, especially brown rice, contains plastic. These rumours have been fuelled by videos showing people bouncing rice balls, as well as videos purporting to show how the rice is made in factories. However, food safety authorities have consistently responded to these rumours by stating that there is no evidence to support the claims that plastic rice is being manufactured and added to real rice.
In 2016, the story gained particular traction in Africa, with Nigerian customs authorities confiscating 2.5 tonnes of rice that they initially claimed was plastic. However, these claims were later refuted by the country's health minister, who stated that there was no evidence of plastic rice. Instead, tests showed that the rice contained high levels of bacteria. Despite this, rumours of plastic rice continued to persist, leading food safety authorities in West Africa, including in Ghana, Senegal, and the Ivory Coast, to address the issue directly. Investigations were carried out, inviting consumers and traders to submit samples of any rice brands they suspected of containing plastic. These investigations consistently found no evidence of plastic rice being sold on the market.
Food safety experts have also pointed out several flaws in the claims that plastic rice is being passed off as real rice. Firstly, plastic is more expensive than rice, so it would not be cost-effective for companies to manufacture and add plastic to their rice products. Secondly, plastic does not expand and cook like real rice; instead, it would shrink or shrivel when exposed to heat. Finally, while some rice may contain a small amount of natural residue or stickiness, there is a noticeable difference between this and the thick layer of melted plastic that would be present if the rice were truly made of plastic.
While there have been no confirmed cases of large amounts of plastic chips being passed off as rice, food safety authorities remain vigilant in addressing these rumours and conducting tests to ensure the safety of the food supply. They have provided methods for consumers to test their rice at home, such as the water test, the microwave test, and the hot oil test, which can help identify any potential issues with the rice. Overall, the consistent response from food safety authorities to the rumours of plastic rice has been one of scepticism and proactive investigation, with a focus on ensuring the safety and integrity of the food supply chain.

Frequently asked questions
There is no evidence that brown rice contains plastic. The rumours of 'plastic rice' being sold in Africa and elsewhere were debunked after investigations.
The rumours started circulating on social media around 2010, with videos showing people bouncing rice balls. The videos claimed that the rice was made of plastic and would bounce when rolled into a ball.
Yes, there are a few simple tests you can do at home to check for plastic in brown rice:
- Water Test: Place the rice in a bowl of water. Real rice will sink due to its density, while plastic rice will float.
- Microwave Test: Microwave equal parts rice and water for 3-5 minutes. If a thick layer of melted plastic forms on the surface, the rice likely contains plastic.
- Hot Oil Test: Heat a pan with a tablespoon of oil. Add a thin layer of rice and observe the grains. If they contract and melt, the rice may contain plastic.
There is no clear answer to this question. Some sources claim that it is a cost-saving measure, while others suggest that it is a way to increase profits by mixing cheaper substances with real rice. However, it is important to note that these are just speculations, and there is little evidence to support these claims.
