Rumors of plastic rice have been circulating since 2011, with reports of rice being produced with potatoes and industrial sticky resin. Social media posts and viral videos of 'bouncing rice balls' have fueled these rumors, particularly in countries dependent on imported rice such as those in West Africa. While there have been claims of plastic rice being sold in Africa and Asia, food fraud experts suggest that it is unlikely that large amounts of plastic chips are being passed off as rice due to the cost. However, research by the University of Queensland found that humans consume approximately three to four milligrams of plastic for every 100 grams of rice, with higher levels found in instant rice. This highlights the importance of understanding the quantity of microplastics present in our food and the potential health risks associated with their consumption.
| Characteristics | Values |

What You'll Learn
Plastic rice in the US is likely a myth
Rumors of plastic rice being sold in the US are likely a myth. While there have been reports of "plastic rice" in various parts of the world, there is little to no evidence to support these claims.
The "plastic rice" rumor first surfaced in 2011 when it was reported that some companies in China were producing fake rice made from potatoes, sweet potatoes, and industrial sticky resin. These reports claimed that the rice stayed hard even after being cooked and that consuming it was equivalent to eating plastic bags. However, there were never any confirmed cases of large amounts of plastic chips being passed off as rice. In fact, producing "plastic rice" from plastic chips would likely be more expensive than using real rice.
In 2016, the rumor resurfaced on social media and spread to Africa, where it gained particular traction in countries highly dependent on imported rice, such as Ivory Coast and Senegal. Nigerian customs authorities even confiscated 2.5 tons of rice suspected to be plastic, only to later backtrack when the country's health minister found no evidence to support the claims.
While there have been instances of food fraud and contamination in both Asia and Africa, the "plastic rice" rumor is likely exaggerated or misinformed. Food safety expert Elliott notes that poorly stored rice can take on a plastic-like appearance, and spraying rice with paraffin wax to make it shine can affect its ability to cook properly. Additionally, while microplastics have been detected in store-bought rice, including pre-cooked and instant rice, this is likely due to contamination during the production process rather than intentional adulteration.
Overall, while the presence of microplastics in rice is a cause for concern and further research, there is little evidence to support the existence of "plastic rice" in the US or elsewhere. The rumor has likely been fueled by a combination of food fraud, misinformation, and exaggeration.

Plastic rice is a food fraud
The idea of plastic rice first emerged in 2011 when reports claimed that some Chinese companies were creating a "fake rice substitute" by mixing potatoes, sweet potatoes, and plastic resins to resemble actual rice grains. These rumours were fuelled by viral videos of 'bouncing rice balls' and statements from restaurant associations, warning that consuming this fake rice was equivalent to eating plastic bags. The concerns over plastic rice were particularly prominent in regions highly dependent on imported rice, such as the Ivory Coast and Senegal, and other parts of Africa.
In 2016, the plastic rice rumours resurfaced on social media, leading to investigations by authorities in various countries. In Singapore, media reports alleged that Chinese companies were mass-producing fake rice made partly from plastic. Similarly, in Indonesia, tests conducted by Sucofindo, a state-owned certification company, found traces of polyvinyl chloride (PVC) and plasticizers in rice samples taken from a porridge shop. These results raised concerns about potential food adulteration and prompted further investigations by the Indonesian government.
Despite the alarming reports and investigations, there is scepticism about the existence of large-scale plastic rice fraud. Food fraud experts suggest that the rumours may be exaggerated or misinterpreted. In some cases, the "plastic rice" could be actual rice that has been poorly stored or treated with chemicals, resulting in an unnatural appearance and texture. Additionally, it is important to distinguish between intentional food fraud and the unintentional presence of microplastics in rice due to environmental contamination.
While the existence of large-scale plastic rice production remains unsubstantiated, the concern over food fraud and the presence of microplastics in rice are valid. The potential health risks associated with consuming plastic or contaminated rice are significant, especially in regions with limited food safety infrastructure and measures. As a result, there is a growing emphasis on developing analytical tools and technologies to detect and deter food fraud, as well as to quantify and understand the impact of microplastics in our food systems.

Plastic rice is made from potatoes, sweet potatoes and plastic
Rumours of plastic rice being manufactured and mixed in with real rice supplies have been circulating on social media since about 2010. These rumours were originally prompted by "fake rice" scandals, although they didn't involve food made entirely out of plastic. In one case, companies were passing off ordinary but edible rice as premium "Wuchang" grains. Then in 2011, reports emerged that rice was being produced with potatoes, sweet potatoes and industrial sticky resin. The "rice" is made by mixing the potato material together, shaping it into grains, and then adding an “industrial resin” as a binding agent. The rice reportedly stays hard even after being cooked.
These rumours were further compounded when a Chinese restaurant association official warned that eating three bowls of "plastic rice" was the equivalent of eating one plastic bag. However, at no point were there confirmed cases of large amounts of plastic chips being passed off as rice. "Plastic rice" is manufactured for use in shipping boxes, but it's likely that in most cases, the cost of the chips would be more expensive than real rice. In addition, it is unlikely that consumers would not notice if their rice tasted like plastic.
The rumour is more popular in countries that are dependent on imported rice, such as Ivory Coast or Senegal. The rumour is so huge that governments are compelled to make statements denying the existence of plastic rice. Food safety authorities in West Africa are addressing the rumours directly, reassuring people that it is fake news.
While there is no evidence of plastic rice in the US, there have been reports of rice being treated with chemicals. In one case, rice was bleached and then sprayed with paraffin wax to give it a shiny appearance. This caused the rice to not cook properly, leading to it being called "plastic rice". However, this is not the same as the plastic rice rumours, which refer to rice made from potatoes, sweet potatoes, and plastic.

Plastic rice is sold in parts of the world with poor food safety infrastructure
While there have been rumours and reports of plastic rice being sold in certain parts of the world, there is little to no evidence to support these claims. The rumours of plastic rice gained traction on social media between 2011 and 2016, with reports claiming that certain Chinese factories were producing fake rice made from potatoes, sweet potatoes, and synthetic resin or plastic. These ingredients were formed into grains resembling actual rice, but remained hard even after cooking. Similar reports have also surfaced in Singapore and Vietnam.
In 2016, Nigerian customs authorities confiscated 2.5 tonnes of rice suspected to be plastic, but these claims were later refuted by the country's health minister due to a lack of evidence. In another incident in Indonesia, tests conducted on rice samples revealed traces of polyvinyl chloride (PVC) and synthetic plasticizers, indicating possible contamination or adulteration.
Food fraud experts suggest that the term "plastic rice" may refer to actual rice that has been poorly stored for a long period, possibly referring to old rice that has been treated with paraffin wax to enhance its appearance. This wax coating may cause the rice to cook improperly, leading to its description as "plastic rice".
It is important to note that the sale of plastic rice is more likely to occur in regions with poor food safety infrastructure and a high dependence on imported rice, such as Sub-Saharan Africa, Southeast Asia, and countries like Ivory Coast and Senegal. These regions often lack the measures to check and test for food safety standards, making them vulnerable to fraudulent food products. However, developed regions like the UK, Europe, and North America have robust government agencies and food industries that actively work to ensure food safety and detect any instances of food fraud.
While the existence of plastic rice as a widespread issue remains questionable, there is ongoing research to develop analytical tests and predictive analytics to detect food fraud and contamination. These efforts aim to address community concerns and increase awareness about potential exposure to plastic and other contaminants in our daily lives.

Washing rice reduces plastic contamination
Rumors of plastic rice have been circulating since 2011, with reports of rice being produced with potatoes and industrial sticky resin. While there have been no confirmed cases of large amounts of plastic chips being passed off as rice, the rumor has persisted, particularly in countries dependent on imported rice such as Ivory Coast and Senegal.
In 2016, the claim resurfaced on social media, with reports that certain rice factories in China were producing a "fake rice substitute" made from potatoes, sweet potatoes, and synthetic resin (plastic). These ingredients were formed into grains that resembled actual rice grains. Tests conducted by Sucofindo, a state-owned certification company in Indonesia, found traces of polyvinyl chloride (PVC) and plasticizers in the rice samples.
While the extent of plastic rice contamination may be exaggerated, there is some truth to the concern. Recent studies have found that washing rice before cooking can reduce plastic contamination by 20-40%. The research, published in the Journal of Hazardous Materials, found that instant or pre-cooked rice had four times higher levels of plastic than uncooked rice, likely due to additional stages of industrial processing.
The study analyzed mass concentrations of selected plastics in store-bought rice and found that polyethylene was the most frequently detected plastic, followed by polypropylene and polyethylene terephthalate. Australians may consume around 3-4 mg of plastic through a single serve of unwashed rice, with this number jumping to 13 mg for instant rice. The researchers hope that their findings will encourage further research into the sources of plastic contamination and ways to reduce it.
Therefore, it is recommended to wash rice before cooking to reduce potential plastic contamination. This simple step can significantly reduce the amount of plastic consumed, especially for those who regularly consume rice as a staple food.
