Why Food Processing Plants Need Specialist Cleaning
Food processing in Ireland is a €30+ billion industry, and it operates under some of the most rigorous hygiene and food safety regulations in the world. The Food Safety Authority of Ireland (FSAI) has the power to close a food production facility immediately if it poses a risk to public health. A failed BRC audit can cost a processor their supermarket contracts overnight. A product recall due to allergen contamination can destroy a brand. In this environment, cleaning is not a housekeeping function — it is a critical food safety control point.
Food processing plant cleaning is fundamentally different from any other type of commercial cleaning. It requires knowledge of food safety legislation (EC 852/2004, EC 853/2004), HACCP principles, allergen management protocols, microbiological standards, chemical compatibility with food contact surfaces, and the specific hygiene requirements of different food types (dairy, meat, fish, bakery, ready meals, fresh produce). Standard commercial cleaning companies lack this expertise.
Optus Glean provides dedicated food processing cleaning teams trained in FSAI requirements, HACCP compliance, allergen management, and BRC audit standards. We work with food processors across Ireland — from artisan producers to large-scale manufacturing plants — delivering cleaning programmes that protect product safety, maintain regulatory compliance, and support audit readiness.
Production Line Cleaning
Production line cleaning is the daily operational cleaning that happens between production shifts, between product changeovers, and at the end of each production day. This cleaning is critical for maintaining hygiene standards, preventing microbial growth, and eliminating allergen cross-contamination between different product runs.
- Equipment exterior cleaning: conveyors, hoppers, fillers, sealers, labellers — all external surfaces degreased and sanitised
- Floor cleaning: production floor degreased, scrubbed, and sanitised using food-safe chemicals and scrubber-dryer machines
- Wall cleaning: tiled or clad walls cleaned from production height to floor
- Drainage: floor drains, channels, and gulleys cleaned, flushed, and sanitised
- Waste management: production waste removed, bins cleaned, waste area sanitised
- Allergen changeover: validated cleaning between allergen-different production runs with swab verification
- Documentation: all cleaning activities logged with time, operative, chemicals used, and verification results
Shutdown and Deep Cleaning
Shutdown cleaning is the comprehensive deep clean carried out during planned production shutdowns — typically at Christmas, Easter, summer maintenance periods, or between seasonal production runs. This is the most intensive cleaning a food processing plant receives, and it addresses areas that daily cleaning cannot reach.
Our shutdown cleaning programme is planned months in advance and executed by large teams to meet tight deadlines. The scope includes complete ceiling-to-floor cleaning of all production areas, dismantling and deep cleaning of accessible equipment components, high-level cleaning of ceilings, beams, ductwork, and light fittings, drainage system deep cleaning and descaling, cold storage defrosting and decontamination, industrial cleaning of plant rooms and utility areas, staff facility deep cleaning including changing rooms, canteen, and offices, and external loading dock and yard cleaning. Every shutdown clean is documented with before-and-after photographs, ATP swab results, and a completion certificate for your HACCP and BRC records.
Allergen Management and Cross-Contamination Prevention
Under EU Regulation 1169/2011, food processors must manage the 14 declarable allergens (gluten, dairy, nuts, soy, eggs, fish, shellfish, celery, mustard, sesame, lupin, molluscs, sulphites, and peanuts) and prevent cross-contamination between products with different allergen profiles. Cleaning is the primary control point for allergen management in most processing plants.
Optus Glean's allergen cleaning protocol includes colour-coded equipment dedicated to each allergen zone, validated cleaning methods tested through allergen-specific and ATP swab testing, documented changeover cleaning procedures, staff training in allergen identification and management, and segregated chemical and equipment storage. We work with your quality assurance team to design allergen cleaning validation programmes that satisfy both FSAI and BRC requirements.
Food Processing Cleaning Pricing
Food processing cleaning pricing depends on the size of the facility, the number of production lines, the type of food processed, and the regulatory standards required. Below are indicative 2026 pricing ranges for Ireland.
| Service | Price Range | Notes |
|---|---|---|
| Small food production unit | €1,500 – €2,500/month | Single line, nightly production clean |
| Mid-sized processing plant | €2,500 – €4,000/month | Multiple lines + cold storage + staff areas |
| Large multi-line facility | €4,000 – €5,000+/month | Full service, multiple shifts |
| Shutdown deep clean | €3,000 – €15,000+ | Full plant, planned shutdown period |
| Allergen changeover clean | €200 – €600 | Per changeover, with swab verification |
| Cold storage deep clean | €500 – €2,000 | Full decontamination, defrost clean |
Note: Prices exclusive of VAT. All pricing includes HACCP-compliant documentation, food-safe chemicals, and trained operatives. Pricing is based on individual site survey and risk assessment.
Staff Facilities and Hygiene Zones
Food processing staff facilities — changing rooms, canteens, hand wash stations, and hygiene airlocks — are critical control points in any food safety system. Poor hygiene in staff areas directly impacts production hygiene. Our staff facility cleaning covers changing room floor, locker, and bench cleaning; washroom and shower cleaning; hand wash station sanitisation and consumable replenishment; canteen cleaning including food preparation areas; hygiene airlock cleaning including boot wash stations and coat storage; and PPE storage areas. These areas are cleaned daily as part of the production cleaning programme.
Serving Food Processors Across Ireland
Optus Glean provides food processing plant cleaning in every county in Ireland. We work with dairy processors, meat plants, fish processors, bakeries, ready meal manufacturers, fresh produce packers, beverage producers, and artisan food producers. Whether you are a small artisan cheese maker in Cork, a meat processing plant in Monaghan, a seafood processor in Galway, or a large-scale dairy facility in Limerick, we have the food safety expertise, the trained teams, and the audit-ready documentation systems to support your production hygiene requirements.
Frequently Asked Questions About Food Processing Cleaning
How much does food processing plant cleaning cost in Ireland?
Food processing cleaning costs between €1,500 and €5,000+ per month in 2026. A small production unit is €1,500–€2,500/month. A mid-sized plant is €2,500–€4,000/month. A large multi-line facility is €4,000–€5,000+/month. Shutdown deep cleans are €3,000–€15,000+ depending on scope.
What is clean-in-place (CIP) and do you provide it?
CIP is an automated method for cleaning process equipment (tanks, pipework, heat exchangers) without dismantling. We support CIP operations by cleaning all areas around and outside the CIP system — equipment exteriors, floors, drainage, walls, and ceilings. CIP equipment operation remains the responsibility of your process engineers.
How do you prevent allergen cross-contamination?
We use colour-coded equipment per allergen zone, validated cleaning methods with ATP and allergen-specific swab testing, documented changeover procedures, staff training in the 14 declarable allergens, and segregated storage. Our protocols meet BRC Global Standard requirements.
Do you provide shutdown cleaning for food factories?
Yes. Shutdown cleans cover complete dismantling and cleaning of accessible equipment, ceiling-to-floor production area cleaning, drainage descaling, cold storage decontamination, high-level cleaning, and staff facilities. Planned months in advance and delivered by large teams to meet tight deadlines.
What food safety standards do you comply with?
We comply with FSAI requirements, HACCP (EC 852/2004), BRC Global Standard, ISO 22000, EU Regulation 1169/2011 (allergens), and Bord Bia Quality Assurance requirements. We provide audit-ready documentation including cleaning schedules, chemical records, swab results, and training records.
Do you clean cold storage and freezer rooms?
Yes. Our operatives are trained for sub-zero work with specialist equipment and PPE. We clean floors, shelving, walls, ceilings, door seals, and drainage. We monitor temperatures throughout cleaning and apply anti-microbial treatments. Defrost cleans during scheduled defrost cycles are also available.
