The case

In a Hutterite Colony in New York, Southern Alberta, black mould contamination was happening in a walk-in cooler.

The Problem

Aspergillus Niger (black mould) spores were reproducing at a high rate, which required a complete washdown and sterilization of
the cooler every week, to prevent individual health issues. Mould would form on the shelves and the necks of the preservative jars.

      Hutterite Colony Walk-In Cooler Coil                                                       Sanuvox Installation at Hutterite Colony

Sanuvox Customized Solution

The cooling unit was cleaned by a refrigeration technician and a Sanuvox IL40-G was installed to destroy the spores early July 2017.

Conclusion

There has not been any reoccurrence of mould in the cooler. Two months after install, the Colony bought two crates of pears, same harvest and variety. They stored the crates in two different walk-in coolers. The pears in the cooler without Sanuvox UV treatment started turning brown and rot within 5 days.

The pears in the cooler with Sanuvox UV showed no signs of degrade. The increase of shelf life of produce impressed the Colony and since then, they equipped the 2nd cooler, along with a root vegetable cold storage room. The Colony is very pleased with the Sanuvox equipment and appreciate having clean cooler with food that is not contaminated with black mould.
