Cleaning & SanitizingQuestion 133 of 319
A cook accidentally mixes a chlorine sanitizer at 400 ppm, much higher than the required range. What is the problem?
a.Higher concentration is always safer and works faster
b.Nothing — the sanitizer just kills more bacteria
c.It can leave a toxic chemical residue and corrode equipment; it must be diluted back to 50–100 ppm
d.It will not kill any bacteria because chlorine is too strong
Explanation
More sanitizer is not better. Chlorine above 100 ppm can leave a toxic residue on food-contact surfaces, corrode stainless steel and aluminum, and irritate skin and lungs. The solution must be diluted to the approved range (50–100 ppm) and verified with a test strip before reuse.
