Si chiama peste europea e - dopo quella americana - è la malattia più temibile per le api. Colpisce le larve, ne causa la morte immediata ed è altamente contagiosa. Il primo focolaio, in un piccolo apiario di Gorduno, è stato scoperto qualche giorno fa.
Tre colonie a Gorduno sono state distrutte, ma questo non pregiudica - almeno per il momento - la produzione di miele. Sono 420 gli apicoltori in Ticino, 618 gli apiari, per un totale di 7’600 colonie di api.
La peste europea è innocua per l'uomo, ma come detto mortale per le api. Agli apicoltori stessi è lasciato il compito di segnalare, agli ispettori poreposti, eventuali anomalie, per bloccare il prima possibile il propagarsi della malattia. In Svizzera si registrano 500 casi all'anno.
