Zebra chip, also known as papa manchada and papa rayada, is a disease in potatoes putatively caused by an alphaproteobacterium "Candidatus Liberibacter solanacearum", which is vectored by the potato psyllid.[2][3] When fried, potato tubers from infected plants develop unsightly black lines resembling the stripes of zebras that render the chips unsellable.[4] Additionally, striped sections of chips frequently burn and caramelize, resulting in a bitter flavor. No health risks have been connected with consumption of infected potato chips.[4]
