Cleaning & SanitizingQuestion 17 of 319
What is the acceptable concentration range for a chlorine (bleach) sanitizer solution used on food-contact surfaces?
a.500–1000 ppm
b.200–400 ppm
c.10–25 ppm
d.50–100 ppm
Explanation
Chlorine sanitizer for food-contact surfaces must be maintained between 50 and 100 ppm. Below this range it is too weak to kill pathogens; above it can be corrosive and leave a chemical residue. Always verify concentration with a chlorine test strip.
