Butcher shop manager - the open-up / close-down double checklist: boards and knives, grinder teardown, cooler temps, fifteen minutes at each end of the day

You are the sanitation and cold-chain consultant for a butcher shop. Build
me an "open-up / close-down" double checklist. Scenario: the manager or the
cutter on duty walks it before opening and after closing, fifteen minutes
per pass, taped to the workroom wall. Respect what makes a butcher shop
different: meat debris and fat clean up far worse than general retail, and
the three hiding places are knife-scored boards, the grinder screw, and
the floor drain. The raw-versus-ready separation rule is an accident the
first time it slips.

OPEN-UP checklist (each line: what to check / pass standard / what to do
on the spot if it fails):
1. Cooler temperature: reading / inside the range I fill in (range follows
   equipment spec and local rules - leave the blank for me) / out of
   range: check the meat before calling repair. A normal cooler reading
   does not clear the meat - first check whether the breaker tripped
   overnight; if it did, touch the meat, look at the surface, and demote
   the whole batch if it isn't cold. No gambling
2. Overnight carryover meat: date labels / every piece labeled, date
   readable / unlabeled piece gets opened, smelled, looked at - doubtful
   goes to write-off, never relabeled. Relabel once and the whole date
   system is dead
3. Cutting boards: surface / no blackened grooves, no discoloration;
   raw-ready markings intact / deep-scored board gets flipped or replaced
4. Knives: sanitation and edge / passed through this shop's routine
   (boiling-water duration or sanitizer cabinet - I fill the standard),
   and slices a sheet of paper / unsanitized: run again; dull knife gets
   honed before the first order
5. Meat grinder: last night's parts / all parts dry, reassembled, test
   run quiet, no residue in the plate holes / any residue: full teardown
   and rewash; a part that still smells stays out of service, reported
6. Scale and price tags: tare zeroed / display reads zero, today's price
   sheet synced / unsynced prices get fixed before opening - a wrong
   price is reliably the day's first complaint

CLOSE-DOWN checklist (same format):
1. Grinder teardown: full disassembly (screw, blade, plate) / every plate
   hole flushed, parts hit with hot water, laid out to air-dry / washed
   parts must NOT be reassembled - trapped water sitting overnight in the
   assembly is worse than not washing
2. Boards: scraped and sanitized / both faces sanitized, stored on edge
   to dry / lying flat does not count as done
3. Knives: honed, washed, homed / every knife in its slot; any missing
   reported tonight
4. Cooler: second temperature check / reading in range, door gasket
   seated with nothing caught in it / a door that won't seal gets dealt
   with tonight - a towel as a stopgap still gets a note for morning
   repair
5. Carryover meat into the cooler: through the end-of-day process /
   date-labeled, on its designated shelf / separated from any
   ready-to-eat items - never the same shelf
6. Floor and drain: rinsed / no meat debris, no grease film in the drain
   / debris gets rinsed before anyone leaves - overnight debris is
   tomorrow morning's smell and pests
7. Trash: hauled same day / bin empty, no overnight meat scraps / arrange
   pickup or freeze the scraps; room-temperature storage does not count

Iron rule (on its own line - never folded into another item):
- Boards, knives, and containers for raw and for ready-to-eat stay
  strictly separate and marked - this rule is an accident the first
  time it fails; "close enough" does not exist here

Constraints:
- No invented sanitizer concentrations, water temperatures, or durations -
  fill from local rules and this shop's equipment; the checklist owns the
  structure, not the numbers
- Every pass standard must be judgeable at a glance - no "keep clean" or
  "free of odor," nothing uncheckable
- Both passes together stay under 13 lines; go over and people start
  skipping, and then the checklist is finished

Why it is written this way

The close-down half outweighs the open-up half, because a butcher shop's sanitation incidents are accumulated at night, not committed during the day shift. "Washed but reassembled" is the most counterintuitive line on the page - a grinder screwed back together wet traps rinse water in the screw and plate threads overnight, which breeds more than leaving it dirty. So the standard reads "laid out to air-dry, do not reassemble." Same logic for the drain debris and the overnight trash: both absent from generic retail checklists, both mandatory in a butcher shop.

"A normal cooler reading does not clear the meat" comes from real incidents: a breaker trips overnight, power returns, and by morning the cooler reads perfectly set-point while the meat inside spent hours warm. So the open-up temperature check chains into the overnight power record, and any doubt gets resolved by touching the meat, not the air. The "never relabel" line rides the same principle: relabel one piece and no one believes a date label again - write-off is cheaper than a dead system.

The raw-ready rule stands alone as an iron rule rather than living inside the boards line, because folding has a fixed outcome: it becomes half a sentence inside "board cleanliness," and then it gets skipped. One line, named, with "an accident the first time it fails" attached - only then does someone own it. That is a general law of checklist design: the highest-stakes item must hold a full row and may never be an adjective for another row.

Blank sanitation numbers are deliberate: concentrations, temperatures, and durations vary by product and jurisdiction, and inventing them makes a sheet of paper on a wall answerable for a product manual's job. The structure forces "blanks must be filled" - and whoever fills them uses this shop's real equipment and local rules. A blank is safer than a printed number, and trusted more.
