Listeria in the floor
causes product recall
and downstream liability.

Listeria monocytogenes and Salmonella spp. live in the biofilm of floor drains in meat, dairy, and fish processing plants. Environmental swab plans find them before they end up in the product — but something must be done about it systematically. Green Drain™ eliminates the P-trap as a reservoir.

Problem & solution

The plant has more P-traps but the operator.

Dairy or meat production has dozens to hundreds of floor drains. The CIP/SIP regime doesn't reach them all. The sanitation inspector demands a documented plan—and the BRC/IFS auditor, during the annual audit, pays special attention to environmental monitoring.

Without Green Drain™

  • Listeria monocytogenes and Pseudomonas colonize P-trap biofilm—chlorine-resistant and biofilm-forming strains
  • Aerosolization during floor washing and sanitation — pathogens reach production surfaces.
  • Positive environmental swab triggers an investigation, retest, and potential recall.
  • EU sanitary inspectors are demanding proven preventive measures.
  • BRC Global Standard for Food Safety and IFS Food require documentation of drain control.

With Green Drain™

  • No standing water in which Listeria, Pseudomonas, and Salmonella thrive.
  • Resistant to CIP/SIP regimes, NaOH up to 5%, HNO₃, peracetic acid, quaternary amines
  • Resistant to temperatures from −40 °C (freezers) to +100 °C (hot CIP)
  • Material compatible with EU 1935/2004 and EU 10/2011 (indirect food contact)
  • HACCP International RG-04 endorsement as a control measure for drainage
EU regulatory framework

Food safety is Legal obligation.

The basic EU framework is Regulation (EC) 178/2002, which sets requirements for food safety and HACCP. Food contact materials are governed by EU Regulation 1935/2004 (framework) and EU Regulation 10/2011 (plastics). BRC and IFS audits are industry standards required by major buyers and exporters in the EU.

Implementation

The entire plant in phases of production.

Large facilities install them on each line during scheduled annual maintenance. One week of coordinated work with the technical service.

01

Mapping

The technician maps all drains by line: intake, processing, packaging, and dispatch.

02

Specification

Written specification with sizes, certificates, and SDS for the QA department.

03

Validation test

Environmental swab pre- and post-test on 10 drains — one month of monitoring.

04

Roll-out

By line in weekly cleaning cycles — without production downtime.

Model Recommendation

Recommendation per on the production line

The Irish meat, dairy, confectionery and bakery sectors operate to BRCGS, IFS, FSAI and Bord Bia Origin Green standards for domestic supply and EU/UK export. A typical Irish processing site runs 4–5 P-trap sizes depending on the line. Central gully channels go up to DN150. Freezers at -25 to -40°C require silicone with thermal-shock resistance — Green Drain™ holds spec across both ends of the range.

Questions

Most common doubts

Will this pass a BRC/IFS audit?

Auditors are requesting documentation of active drain control as part of the environmental monitoring program. The HACCP Int. RG-04 endorsement plus our SOP template meet the requirement.

Resistance to CIP/SIP cycles?

Silicone is resistant to NaOH up to 5%, HNO₃ up to 3%, peracetic acid up to 2%, and quaternary ammonium compounds. It can withstand continuous thermal exposure up to 100 °C and short-term exposure up to 120 °C.

Can we get a food-contact certificate?

The material is compliant with EU 1935/2004 and EU 10/2011 for indirect food contact via the drainage system. We will provide the SDS and the Declaration of Conformity upon request.

Complete solution

Three products.
One protection portfolio.

Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (biofilm bio-cleaning).
