In the two-stage cooling method, after reaching 70°F the food must be cooled to 41°F within how many additional hours?
a.2 additional hours
b.6 additional hours
c.4 additional hours
d.8 additional hours
解析
After the first stage brings food to 70°F within 2 hours, the second stage must bring it from 70°F down to 41°F within 4 more hours, for a maximum total of 6 hours. Allowing more time would keep the food in the danger zone too long and permit pathogen growth.
