Le autorità sanitarie canadesi hanno ordinato l'abbattimento, nella regione occidentale della Columbia Britannica, di 146'000 volatili in cinque allevamenti colpiti dall'influenza aviaria del tipo H5N2.
Il ceppo è particolarmente contagioso e letale per gli animali, ma, contrariamente al tipo H5N1, difficilmente si trasmette all'uomo.
L'Agenzia canadese d'ispezione alimentare ha inoltre fatto sapere di aver definito un vasto perimetro di sicurezza nel quale sarà proibito trasportare volatili, carne, uova o alimenti che possono essere entrati in contatto con gli animali infetti.
