The article highlights changes in the perishable commodities trade in North America due to seasonal shifts, with a focus on blueberries and avocados. It notes a decline in Peru's blueberry imports as the season ends, but trade in the US remains steady with low prices. Avocado trade from Mexico to Texas also remains stable, but at slower trading speeds with slightly lower prices for some sizes. In contrast, cucumber movement from Mexico to Otay Mesa, California, is expected to decrease, leading to more active trading and higher prices, while the flow through Texas is expected to remain similar.
