1982 – THE NEXT BIG STEP

The Pia family, through its marketing division of South Mill Mushroom Sales, purchased their Kennett Square, Pennsylvania mushroom-growing operation from the Clorox Corporation. Clorox operated the facility under the “Grocery Store Products” label, selling predominantly to the cannery markets. South Mill converted the production of this facility to the fresh market, which was just beginning to develop in the United States.

1984 – Vacuum Cooling

Vacuum cooling, a technology only recently available at the time, is implemented via the purchase of a 15,000 pounds capacity vacuum cooler, providing the ability to properly cool mushrooms in just 20 minutes versus the 24 hours it previously took in typical cold storage coolers.

1986 – Direct Harvesting

1986 – Direct Harvesting

South Mill converts from the prior standard harvesting practice of dumping mushrooms into the final sales container at the packing area to a practice of harvesting directly into the final sales container at the farm level, thereby reducing bruising and improving quality and shelf-life.

The company has multiple trucks per day connecting through the city of Atlanta.

South Mill was one of the first mushroom farms in the country to install modern logistics technology in its over-the-road refrigerated transportation fleet. This allows “in-transit” data to be communicated in real-time. Important delivery data including, change of schedule, change of delivery locations and estimated times of arrival (ETA) can be communicated to the customer. With one of the largest geographic distribution footprints of any mushroom farm in North America, the goal of efficiently communicating on a 24/7 basis, with trucks travelling thru most every major city east of the Rockies, and in Canada, underscores the company’s commitment to customer service.
