Listeria monocytogenes and Salmonella spp. persist in the biofilm of floor drains in meat, dairy and fish processing plants. Environmental swabbing finds them before they reach the product — but the reservoir itself has to be dealt with systematically. Green Drain™ takes the standing water out of the trap.
Dairy and meat sites run dozens to hundreds of floor drains, and the CIP/SIP regime does not reach them all. Approved meat and dairy plants are supervised by the Department of Agriculture, Food and the Marine; other food businesses are inspected by the HSE Environmental Health Service on behalf of the FSAI. Both expect a documented cleaning and monitoring plan — and where a customer requires BRCGS or IFS certification, the auditor pays close attention to environmental monitoring.
The HACCP duty comes from Regulation (EC) 852/2004 on the hygiene of foodstuffs, given effect in Ireland by the European Union (Food and Feed Hygiene) Regulations; Regulation (EC) 178/2002 sets the wider general food law framework. Food contact materials are governed by Regulation (EC) 1935/2004 (framework) and Regulation (EU) 10/2011 (plastics). BRCGS and IFS are private GFSI-benchmarked schemes — not law, but commonly demanded by buyers and exporters.

Larger sites fit them line by line during scheduled annual maintenance — typically a week of coordinated work with the engineering team.
The technician maps all drains by line: intake, processing, packaging, and dispatch.
Written specification with sizes, listings and the safety data sheet for the QA department.
Environmental swab pre- and post-test on 10 drains — one month of monitoring.
Line by line during weekly cleaning cycles — no production downtime.
Irish meat, dairy, confectionery and bakery sites work to EU food hygiene law — enforced by DAFM in approved plants and by the HSE Environmental Health Service elsewhere — and most also hold a private certification such as BRCGS or IFS, or take part in Bord Bia's voluntary Origin Green programme. A typical processing site runs four or five drain sizes depending on the line, with central gully channels up to DN150. Freezers at −25 to −40 °C need silicone that tolerates thermal shock; Green Drain™ is rated from −40 °C to +100 °C.
BRCGS and IFS are private schemes, so it depends on your auditor and on your own environmental monitoring programme. We can supply the HACCP International RG-04 listing, the NSF/ANSI 2 listing (C0571796) and an SOP template as supporting evidence. Whether a drain measure belongs in your HACCP plan — and whether it is a critical control point — is decided by your own hazard analysis, not by us.
The silicone resists NaOH up to 5 %, HNO₃ up to 3 %, peracetic acid up to 2 % and quaternary ammonium compounds. Its rated operating range is −40 °C to +100 °C, so hot CIP is fine, but do not use it where live steam or wash-down above 100 °C reaches the drain.
The material is compliant with EU 1935/2004 and EU 10/2011 for indirect food contact via the drainage system. We provide the safety data sheet and the Declaration of Conformity on request.
Green Drain™ works best alongside GD Uri-Tabs™ for staff urinals and GreenSwirl™ for clearing build-up in the run.
Patented silicone valve for floor drains in processing plants, cold stores and packing houses. Material compliant with EU 1935/2004; a drain control measure your own hazard analysis can take into account.
Bio-enzymatic urinal tablets for staff washrooms — a 30–45 day lifetime per tablet, and nothing that goes near production areas.
Mineral and bacterial granules for fat and organic residue in production drains — dosed with a little warm water, left 15–30 minutes, then flushed through with plenty of hot water. No harsh alkalis.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
