Chestnut pumpkins, known for their green skin and sweet, chestnut-like flesh, have surged in popularity in Vietnam, fetching prices three times higher than local varieties. This demand is partly fueled by social media promotion. Importers have noted a significant rise in both volume and price compared to previous years. Authorities stress the importance of strict quality control and caution against buying smuggled goods, following a recent seizure of illegally imported pumpkins in Hanoi.
