1. Training sessions on Good Agricultural and Handling Practices
should be done at different supply chain segments.
Introduction
2. Controlling temperature, humidity and sunlight during the
handling process is crucial to reduce postharvest losses.
The Caribbean region is characterized by its tropical climate with year-round
sunshine, separated into dry and wet seasons. The environmental conditions
under which fresh horticultural commodities are produced, transported and
displayed have a significant effect on the keeping quality of the food and the
amount that is lost. A relevant problem in the region is “inefficient postharvest management practices” resulting in a high level of postharvest losses
and major issues of food quality and quantity.
3. The use of simple interventions, such as umbrellas or any bright
colored textiles to protect the produce from direct sunlight and
high temperature can significantly reduce postharvest quality
and quantity loss.
Tomato spoilage
Inadequate on-farm storage
Inappropriate crop display
4. Developing a user-friendly “Post-Harvest Quality Loss
Management Guide” for each segment of the supply chain in
CARICOM countries is necessary to illustrate several quality
management interventions.
This study was undertaken in St. Kitts-Nevis and Guyana to assess postharvest practices and losses during production and marketing of locally
grown fruits and vegetables (Tomato, String Beans, Eggplant, Cucumber and
Okra).
