Reducing Spoilage Risks in Perishable Goods Storage

Minimize Losses. As a general rule, the lower the average storage temperature and the larger the storage space, the more slowly spoilage is likely to develop. Smaller spaces, like display cases or walk-in coolers, can experience spoilage loss in a matter of hours.
