Michelin-starred South Korean chef faces jail over illegal ant garnish in desserts

A Michelin-starred restaurant owner in South Korea faces a possible jail sentence after authorities found the restaurant used thousands of unapproved ants as dessert toppings.

Michelin-starred chef investigated after serving ants in desserts

A Michelin-starred restaurant owner in South Korea could face a prison sentence after prosecutors accused the establishment of illegally using ants as a garnish in desserts.

Prosecutors have requested a one-year jail term for the owner of the two-Michelin-star restaurant, along with a fine of 20 million Korean won, which is approximately $13,510 or £10,100.

The case has attracted international attention because the unusual ingredient was not linked to a food safety issue alone, but also to South Korea’s strict regulations surrounding edible insects.

Authorities said the restaurant used ants as toppings for certain desserts, including sorbets, despite ants not being included among the insect species officially approved for human consumption in the country.

The owner admitted that ants had been served at the restaurant but argued that they were only a small part of the restaurant’s 15-course tasting menu. The restaurant also claimed that customers were informed about the ingredient and were offered alternative toppings if they did not want to eat ants.

Thousands of ants used in restaurant dishes

According to investigators, around 49,000 ants were used in different dishes over a period of four years.

The insects were reportedly imported from countries including the United States and Thailand. Officials from South Korea’s Ministry of Food and Drug Safety discovered evidence of the practice after reviewing online restaurant reviews where customers had uploaded photographs showing dishes decorated with ants.

The investigation raised concerns because authorities found that the ants used by the restaurant contained high levels of heavy metals.

A report cited by local media stated that the insects contained up to 55 times more heavy metals than commonly approved edible insects. Food safety officials said these findings contributed to concerns about whether the ants were suitable for consumption.

South Korean authorities assess several factors before approving insects as food. These include possible health risks, toxicity levels, nutritional value, and whether the insects can be safely raised, processed, and distributed.

Restaurant defends use of ants as an ingredient

The restaurant owner defended the decision by saying that diners were given a choice.

According to the defence, only around 60% of customers chose to try the ant-topped dishes. Other diners received alternative versions featuring ingredients such as fermented vinegar or edible flowers.

The owner also argued that ants are used as culinary ingredients in other parts of the world, including countries such as Australia, Denmark, and the United Kingdom.

In many cultures, insects are considered traditional foods and are valued for their flavour, nutritional content, and cultural significance. Ants and other insects are eaten in parts of Asia, Africa, and Latin America.

For example, weaver ants and ant eggs are used in some Thai and Cambodian dishes. In Colombia, queen ants are considered a delicacy and are sometimes compared in value to luxury foods such as caviar.

The owner’s argument suggests that the use of ants should be viewed through a global culinary perspective rather than only through South Korean food regulations.

South Korea’s strict edible insect rules

Although insect-based foods have gained popularity worldwide as a sustainable source of protein, regulations differ significantly between countries.

South Korea currently allows only certain insect species to be sold as food. Approved insects include grasshoppers, locusts, and two-spotted crickets.

Ants are not included on the approved list, meaning restaurants and food producers cannot legally use them as ingredients without official approval.

Food safety authorities have said that approval decisions require detailed scientific evaluation. Researchers examine potential allergic reactions, contamination risks, nutritional benefits, and production standards before allowing an insect species to enter the food market.

The case highlights the challenges faced by chefs experimenting with unusual ingredients while operating under strict food safety laws.

Michelin recognition adds attention to the case

The restaurant involved has not been publicly named in court documents. South Korea has only a limited number of restaurants holding two Michelin stars, with ten such establishments located in Seoul.

The Michelin Guide awards restaurants up to three stars based on factors including ingredient quality, cooking techniques, flavour, creativity, consistency, and the personality of the chef.

A two-star rating means the restaurant offers “excellent cooking” and is considered worth making a special trip to visit.

Because of its prestigious Michelin status, the case has received additional attention from the food industry and the public.

The situation also raises questions about the balance between culinary creativity and legal responsibility. High-end restaurants often experiment with rare ingredients and unusual combinations, but chefs must still follow national food safety regulations.

Court decision expected in September

A South Korean court is expected to announce its verdict on 2 September.

The final decision will determine whether the restaurant owner receives a prison sentence or another form of punishment.

The case could influence future discussions about the use of unconventional ingredients in South Korea’s growing fine-dining industry. As chefs continue exploring new flavours and sustainable food sources, regulators may face increasing pressure to evaluate new ingredients while maintaining strict safety standards.

For now, the ant garnish controversy remains a unique legal battle involving food innovation, cultural traditions, and national safety rules.
