Gli svizzeri sono i maggiori acquirenti al mondo di uova biologiche: una su cinque di quelle comperate nel commercio al dettaglio, infatti, proviene da piccoli allevamenti dove le galline razzolano in spazi aperti e vengono alimentate in modo "naturale". È quanto indica un rapporto pubblicato oggi (sabato) dall'Ufficio federale dell'agricoltura.
Lo studio evidenzia come nel periodo fra il 2012 e il 2015 i prezzi delle uova biologiche fossero in media più alti del 35% rispetto a quelli da allevamento all'aperto (a causa degli elevati costi di allevamento degli animali). L'80% delle uova prodotte lo scorso anno in Svizzera proveniva da queste due filiere.
