Edible insects on the menu for an industry with legs

How about topping your toast with witchetty grubs, or adding some crunch to your cooking with crickets? Even your trendsetting smoothie bowl could become more Instagram-worthy with a handful of bogong moths.

According to the CSIRO, the global billion-dollar edible insect industry could have legs here in the Canberra region as Australia takes flight by producing nutritious, sustainable and ethical products to support global food security.

CSIRO’s Canberra-based entomologist Dr Bryan Lessard has co-authored a report called ‘Edible insects: A roadmap for the strategic growth of an emerging Australian industry’, which lays out a comprehensive plan for the emerging industry that has a strong focus on more than 60 native insect species traditionally consumed by First Nations peoples in Australia.

Dr Lessard said the report highlighted the importance of supporting and promoting First Nations-led enterprises.

“The roadmap draws on the expertise of Australian and international scientists, Aboriginal and Torres Strait Islander peoples, insect farmers, and food processing industry leaders and chefs to set out the challenges and opportunities presented by one of the world’s richest sources of protein and other micronutrients,” he said.

“Australia has a high diversity of native insects. Working with First Nations enterprises, many species have the potential to be sustainably harvested or grown in low-impact farms, to be turned into new and delicious Australian foods for us and our pets.”

Dr Lessard also said commercial insect farming has a low environmental footprint, requiring minimal feed, water, energy and land resources, which are factors becoming more important to people making healthy and ethically conscious food choices.

Co-funded by CSIRO and the Department of Foreign Affairs and Trade through the Council on Australia Latin America Relations, the roadmap provides a framework within Australia for First Nations initiatives, startups, insect businesses, researchers, policymakers and community members interested in engaging with the industry.

CSIRO researcher and report co-author Dr Rocio Ponce Reyes said the global edible insect industry is growing fast.

“The worldwide edible insect market is expected to reach $1.4 billion AUD in value by 2023,” she said. “Europe and the US lead the western world market, with more than 400 edible-insect-related businesses in operation.

“Insects have high-value nutritional profiles and are rich in protein, Omega-3 fatty acids, iron, zinc, folic acid and vitamins B12, C and E.

“They are also complementary to our existing diets because they are healthy, environmentally friendly and a rich source of alternative proteins.”

More than 2100 insect species are currently eaten by two billion people from 130 countries, including iconic Australian species such as witchetty (or witjuti) grubs, bogong moths, honey pot ants and green tree ants.

The roadmap also sets out challenges to overcome, including scalability, consumer appetite and research opportunities, and provides options to tackle them, including new products, innovations to farming and collaboration.

The CSIRO research is also looking at alternative protein sources needed to meet the demands of a global population estimated to reach 9.7 billion people by 2050.

Through its developing Future Protein Mission, Professor Michelle Colgrave said the focus is on helping Australia capture high-growth global protein markets.

“Alternative protein industries can play an important role in Australia, contributing to regional and national prosperity,” she said. “At CSIRO, we’re researching plant-based protein, traditional protein sources and emerging protein industries including edible insects.”

The roadmap is available in English and Spanish, allowing connections between Australia and Latin America, such as Mexico, where eating insects is more widespread. It provides guidance for Spanish-speaking countries on how to develop their local industries.
