Avocado prices surge to a 24-year high

Avocado prices jumped to the highest in more than two decades amid tightening supplies in Mexico, the world's biggest exporter of the fruit, signaling pricier guacamole.

An index tracking avocado from the Mexican state of Michoacan, by far the biggest source in the country, climbed 81% this year to 760 pesos ($38) per 9-kilogram box, the highest in data going back to 1998, government figures showed.
