Tomato and sweet potato prices have significantly increased in Paraná, Brazil, with the saladete variety of tomatoes seeing an 83% rise in September, and sweet potato prices nearly increasing by 26%. This is due to reduced production areas in Goiás and São Paulo due to low prices and adverse weather conditions, respectively. In contrast, rice prices have decreased by 3.72%, but this is not yet reflected in retail prices as consumer demand has driven a 5.17% increase.
