Kraft Heinz is planning to increase the production of its single-serve ketchup packets by 25%, leading to a 25% increase in demand for processing tomatoes. This demand is putting pressure on the processing tomato crop in the Central Valley of California, especially in Fresno County, which grows about a third of the state's processing tomatoes. The price of processing tomatoes has risen about 8% over the past year, and farmers are waiting to hear more about possible new groundwater regulations that could limit the amount of water available for tomato farming, potentially driving the cost of tomatoes up even further.
