The article reports a significant increase in the price of onions in the Metropolitan Area of Guadalajara, Mexico, with prices reaching up to 56 pesos per kilo in self-service stores and 29 pesos in city markets. The price variation is noted across different retailers. The surge in onion prices is attributed to a drop in production, damage to crops due to lack of rainfall during the spring-summer 2022 cycle, and an overall inflation rate of 87.26% for the product during the first half of September. Onion is a key crop in Mexico, with production primarily concentrated in states like Chihuahua, Zacatecas, Guanajuato, Tamaulipas, Michoacán, Puebla, and San Luis Potosí.
