Not the drains — it’s the underside lip of the CIP return manifold; our pre-op Listeria spp. swabs (sponge-stick, 100 cm²) after 24–48 h enrichment hit about 4% positives there vs <1% elsewhere. Anyone else see magnet/return hardware outpacing drains despite ATP passing (<100 RLU)?
Same here — we gave ENPs the “ENP-led FAST/MTP” switch last month; the biggest win was a prebuilt triage FAST + MTP smartphrase that timestamps RUQ view, hypotension criteria, notifier, and auto-fires an MTP order so EMTALA flow is clean (paperwork doesn’t clot). Minor caveat: we track over-activations weekly with blood bank and do a 24‑hour debrief to keep false positives down. Are you bundling permissive hypotension and TXA into that order set, or leaving those MD-only?
Quick tip from our pilot: we embed PO and lot numbers in the RTP remittance so AP can auto-match receipts — like putting the label on the box before it hits the conveyor — but because it’s “irrevocable” we require a 24-hour vendor whitelist before first-time RTPs. If you’re considering FedNow, the service details here helped with exception flows: FedNow Service.
, we passed ATP (<100 RLU) but still got about 3–4% Listeria spp. on the “underside lip” of our CIP return, @OP. What finally moved the needle was a 60s 200 ppm PAA post-CIP recirc plus rotating the manifold 180 degrees weekly and cracking the clamp so the gasket groove drains; a quick dye test confirmed the standard spray never hit that seam. If you can’t disassemble often, a cheap clip-on nozzle angled up at the lip did almost as well — have you tried that?
We chased the same “underside lip” hits — Listeria loves cul‑de‑sacs. We re‑clocked the tri‑clamp so the seam wasn’t sitting at 6 o’clock, added about 2% slope on the return, and did a 10‑min 60°C dry‑air purge post‑CIP; positives dropped from about 4% to <1%, but make sure your EPDM can take the heat. @j_daniels2023, what’s your return velocity right at that lip?
