Burgundy snail farms suffer catastrophic losses amid record heatwave
Snail farmers in Burgundy are confronting severe mortality as the summer heatwave intensifies. Frédéric Marcouyoux, who runs La Ferme au gré du temps in Villecomte (Côte‑d’Or), normally raises 200,000 snails a year, but this season he expects only about 100,000 to survive. He described the situation as “an hécatombe” and said, “All the income is on the ground.” The extreme dryness and soaring temperatures have made the snails especially vulnerable, with past heatwaves causing 70‑80 % losses in 2019‑2020 and 50‑60 % in 2021. Predators such as birds are also turning to the weakened snails for food.
Another producer, Hervé Ménelot of L’Escargot dijonnais in Fénay, faces similar devastation. He cultivates 500,000 snails and anticipates a 50‑70 % loss, noting that the once‑lush vegetation is now burnt straw. Both farmers stress that snails need moisture and shade, and they are diversifying with sheep, beehives and fruit trees to mitigate the impact. The growers question whether snail farming can continue under increasingly frequent and violent heatwaves, highlighting the broader challenge for agriculture in a warming climate.
