Two sinks, no test strips, one cutting board
The dish machine has been waiting three weeks for a sanitizer pump, and the test strips ran out last Friday; the new box arrives Thursday. The kitchen has a two-compartment sink and a bucket of chlorine sanitizer mixed at 8:00 a.m. that nobody measured - it smells strongly of chlorine. At 11:00 a.m. the cook cuts raw chicken on the white cutting board, rinses the board under the tap for about ten seconds, wipes it with a cloth from the bucket, and uses it to prep the salad. A server uses that same cloth on the front counter and tables between orders. The bucket is still on the counter at 3:00 p.m., and the cook tops it up with water and a splash of bleach.
1. What is wrong with how the cutting board was handled, and what is the correct procedure with only two sinks and no test strips?
Read the worked answer
A ten-second rinse is neither cleaning nor sanitizing. Raw chicken leaves a protein film that shelters bacteria, and rinsing spreads the contamination around the board and into the sink.
Correct sequence:
- Scrape and wipe off food debris.
- Wash in hot soapy water in sink one.
- Rinse in clean water in sink two - this step cannot be skipped, because leftover soap and food residue neutralize chlorine.
- Sanitize in a clean container of 100 ppm chlorine for 2 minutes' contact time (or the concentration and time on the label), then air-dry on a rack. Do not towel dry.
With two sinks, the sanitizing step happens in a separate clean container, not in the wash water and not by default.
The missing strips are the real blocker. Without them you cannot confirm 100 ppm: too weak does nothing, too strong is a chemical hazard on a food contact surface. A strong smell is not a measurement. Until strips arrive, the defensible options are heat - scrub, rinse, then flood with or immerse in boiling water - or a clean spare board reserved for ready-to-eat work. Do not prep salad on a board you cannot prove was sanitized. And wash hands after raw chicken, before touching the salad: the board is only half the cross-contamination route.
2. What is wrong with the sanitizer bucket and the wiping cloths, and how should they be managed?

The bucket is doing the opposite of its job. Chlorine loses strength in the presence of food soil, warmth, and light. A solution mixed at 8:00 a.m., used on a raw-chicken board and then on tables, and 'topped up' at 3:00 p.m. with water and an unmeasured splash has an unknown concentration and is now a cloudy soup of food residue. Re-dipping returns bacteria from the cloth to the surface you just wiped.
Fixes:
- Mix fresh sanitizer by measured dilution exactly as the label states, using a measuring spoon, and verify with a test strip.
- Change the solution every 2–4 hours, or sooner if it looks cloudy, greasy, or has visible debris. Never top up - discard and remix.
- Keep separate cloths for raw-food areas and for ready-to-eat and customer-contact surfaces. The raw-side cloth must never go to the front counter.
- Store cloths submerged in the sanitizer, not draped over the edge of the bucket, and use a fresh cloth rather than reusing one that has wiped a raw prep surface.
3. Rank today's problems by risk and say what you would do before the next order leaves the kitchen.

Risk ranking, highest first:
- The salad board. Ready-to-eat food with no kill step, prepared on a board that was rinsed and wiped rather than cleaned and sanitized. Correct it first: stop salad prep, obtain a clean and properly sanitized board (heat method if strips are unavailable), and rewash hands. If the salad was already made on that board, discard it.
- Every food contact surface cleaned since Friday with unverified sanitizer. Without strips, no one can say surfaces were sanitized. Move to the boiling-water method for small items and get strips in today - borrow from another business, buy from a nearby supplier, or close the affected prep until the box arrives.
- The bucket and cloths - contaminated, hours old, used across raw and ready-to-eat zones. Remix, separate, and retrain.
- The dish machine. Three weeks down means hand-sink dishwashing is the routine, which needs a documented three-step procedure, not improvisation.
Then fix the system: keep a backup box of strips, a written cleaning and sanitizing schedule with initials, and a rule that no sanitizing step happens without a verified concentration. 'It looked clean' is not a standard anyone can be held to.
