It’s not that much of a loss for them. If you are growing for someone like morning star, they have tightened the supply chain so well that every step is precisely executed. The reason they are open topped is because they go straight to processing and get washed and graded and processed even before they are weighed. It’s beautiful how the system has been designed. Closing the tops is probably saving less than a few pennies per pound but it’s not worth disrupting or delaying the operations systems. Processing company contract out every step of the growing process from nursery to transplanting services to harvesting. Chris Rufer is a model most of us should strive to be..he has perfected tomato processing to an art form.
