What is the maximum cold holding temperature allowed for shredded lettuce?

The maximum safe cold holding temperature for shredded lettuce is 41°F (5°C) or lower. This is a crucial temperature to prevent the rapid growth of harmful bacteria like E. coli and Salmonella, which can cause foodborne illness. Maintaining this temperature consistently is vital, especially considering the high surface area of shredded lettuce which increases the risk of contamination. Any temperature above 41°F significantly increases the risk.
