The bread contains more protein than normal wheat bread, according to Fazer, with each loaf containing about 70 crickets.
Fazer Sirkkaleipä (Fazer Cricket Bread), which lists flour made from ground house crickets (Acheta domesticus) as an ingredient, is now available in Fazer's 11 in-store bakeries located in Finland.
The farm-raised crickets are estimated to make up about three percent of the bread's weight.
Markus Hellstrom, head of the store's bakery said: "Finns are known to be willing to try new things".
Insects are a sustainable food source and are predicted to be eaten by everyone in 2030
Juhani Sibakov, director innovation at Fazer Bakery Finland, said: "We made a crunchy dough to enhance taste and increase mouthfeel". The result was 'delicious and nutritious'.
While insect-based food remains something of a rarity in the western world, around 2 billion people eat insects worldwide.
He added: "Mankind needs new and sustainable sources of nutrition". Using insects in foods is relatively new in countries such as Finland but the country is said to be one of the most interested in this idea. Earlier this month, Finland became the fifth country in Europe to allow selling insects marketed as food items, joining the U.K., Austria, Belgium, Denmark, and the Netherlands. "The first-in-the-world Fazer Cricket Bread is a great example of this". A survey done past year by Turku University and the Natural Resources Institute found that half of the participants would buy foods with insects if they were sold in the country.
The agency says many types of insects produce less greenhouse gases and ammonia than most livestock - such as methane-spewing cattle - and require less land and money to cultivate.
