FROM THE FIELDS: West Coast Heat Spike

September 26, 2016

Many California growing regions, including Salinas, Santa Maria, and Oxnard, are currently experiencing a significant heat spike with daytime highs rising into the upper 80s to low 100s; nearly 20 degrees above normal. The elevated temperatures and dry conditions are the result of strong high pressure and offshore flow, that is expected to reverse back to onshore flow by mid-week and start a cool down period leading into the weekend.

Markon inspectors have just started to observe heat-related quality issues such as dehydration, elevated insect pressure, and a small amount of internal burn and long core/seeder in lettuce items such as green leaf, iceberg, and romaine. Strawberries and tender leaf items like arugula, spinach, and spring mix are especially sensitive to extreme temperature fluctuations and may also begin to develop quality and shelf-life concerns in the coming days.

Cold-chain management throughout distribution is a critical part of maximizing the quality and shelf-life of perishable produce items. Ordering for quick turns is also recommended. Markon inspectors will be monitoring commodity and value-added items very closely and will update further as needed.
