Temperature Monitoring and HACCP Compliance for Greek Cafes

HACCP: The Foundation of Food Safety

HACCP (Hazard Analysis and Critical Control Points) is the internationally recognized food safety system, mandatory for Greek food businesses under EFET regulations. It shifts food safety from reactive (fixing problems after customers get sick) to preventive (stopping hazards before they occur). For cafes, HACCP focuses on identifying where food hazards enter your operation (raw ingredients, contaminated equipment) and implementing controls (temperature monitoring, cleaning) to eliminate risks.

The Seven HACCP Principles

Principle 1: Conduct Hazard Analysis Identify all potential hazards in your cafe—biological (bacteria, viruses), chemical (cleaning supplies, pesticides), and physical (glass, metal). For a typical cafe: raw milk could harbor Listeria, espresso equipment could contaminate drinks if improperly cleaned, and prepared items left at room temperature could grow pathogens.

Principle 2: Determine Critical Control Points (CCPs) Identify specific steps where you can control identified hazards. For a cafe: refrigeration temperature (CCP for dairy and prepared foods), espresso equipment sterilization (CCP for milk-based drinks), handwashing (CCP for cross-contamination prevention).

Principle 3: Establish Critical Limits Define the safe operating parameters for each CCP. Examples: "Refrigerator must maintain 2-4°C," "Espresso equipment steam wand must reach 82°C," "Dishwater must reach 82°C for final rinse."

Principle 4: Monitor Critical Controls Implement monitoring procedures checking that CCPs stay within limits. Examples: Check refrigerator temperature daily at 8am, test dishwasher final rinse temperature daily, observe handwashing technique during shift.

Principle 5: Establish Corrective Actions Create procedures for when CCPs fall outside limits. Example: "If refrigerator drops below 2°C, contact technician and move perishables to backup cooler until resolved."

Principle 6: Establish Verification Procedures Confirm that monitoring is occurring and CCPs are controlled. Review daily logs weekly. Conduct monthly equipment calibration checks. Audit handwashing compliance quarterly.

Principle 7: Establish Record Keeping and Documentation Maintain 12+ months of monitoring records, corrective action logs, verification documentation. These prove to EFET that you're actively controlling food safety.

Identifying Critical Control Points for Your Cafe

Most cafes have 4-6 primary CCPs:

CCP 1: Supplier and Delivery Hazard: Contaminated food arriving from suppliers. Control: Inspect deliveries for temperature, expiration dates, damage, and pests. Accept only from approved suppliers with food safety certifications.

Critical Limit: Dairy received at 4-8°C, foods received in undamaged packaging, supplier health certification current.

Monitoring: Check temperature of delivered milk with thermometer. Verify expiration dates. Inspect packaging integrity.

Frequency: Every delivery (daily or weekly depending on supplier schedule).

Corrective Action: If temperature out of range, refuse delivery. Request replacement.

CCP 2: Cold Storage Temperature Hazard: Pathogenic bacteria growth in stored food. Control: Maintain refrigeration at 2-4°C.

Critical Limit: 2-4°C for all refrigeration units.

Monitoring: Check thermometer in each refrigeration unit daily (morning, before opening). Record temperature and time.

Frequency: Daily (7 days/week).

Corrective Action: If temperature exceeds 4°C, investigate (thermostat issue? door left open? equipment failure?). For temporary elevation (4-5°C): monitor every 2 hours until back to normal. For significant elevation (above 5°C): use backup cooler, call technician, document all actions.

CCP 3: Equipment Sterilization (Espresso Machine and Milk System) Hazard: Milk residue and bacterial growth in espresso equipment. Control: Daily disassembly and sterilization of milk-contact surfaces.

Critical Limit: All milk-contact surfaces disassembled and cleaned daily, steam wand soaked in cleaning solution or run through sanitizer.

Monitoring: Visual inspection of equipment at close (steam wand, portafilter, basket). Check cleaning logs.

Frequency: Daily (at end of shift).

Corrective Action: If cleaning not completed, document and have staff immediately complete cleaning before equipment sits overnight. Review cleaning procedures with staff.

CCP 4: Dishwashing and Cup Sanitation Hazard: Contaminated cups, spoons transmitting foodborne illness. Control: Mechanical dishwasher or three-compartment sink with adequate temperature and sanitizer.

Critical Limit: Final rinse temperature 82°C+, sanitizer concentration 100-200ppm chlorine (or equivalent), all visible food debris removed before washing.

Monitoring: Check final rinse temperature with sanitizer test strip daily. Observe washing procedure for proper technique. Check test strips for sanitizer concentration.

Frequency: Daily (before opening, mid-shift, end of shift).

Corrective Action: If temperature below 82°C, increase water heater temperature or repair equipment. If sanitizer concentration low, add sanitizer per product instructions. If equipment malfunctions, use backup three-compartment sink or close until repaired.

CCP 5: Handwashing Facilities and Hygiene Hazard: Cross-contamination from hands touching ready-to-eat foods. Control: Accessible handwashing with hot water, soap, and sanitation.

Critical Limit: Handwashing stations available and stocked, hot water (38-48°C) flowing, staff wash hands before food handling and between tasks.

Monitoring: Visual inspection during shifts: soap/towels stocked? Hot water flowing? Observe staff washing hands at appropriate times. Monitor compliance during busy periods.

Frequency: Multiple times daily (observe at least 4 different times during shift).

Corrective Action: If soap/towels depleted, restock immediately. If hot water unavailable, fix heating system or use alternative (hand sanitizer + soap for temporary measure, though not replacement). If staff not washing hands appropriately, provide coaching and monitor next 5 times they should wash.

CCP 6: Ready-to-Eat Food Holding Temperature Hazard: Pre-prepared foods left at room temperature, pathogenic growth. Control: Maintain prepared foods (sandwiches, pastries) at safe temperatures or consume within safe timeframes.

Critical Limit: Ready-to-eat foods held at 4°C or below, or consumed within 4 hours of preparation at room temperature.

Monitoring: Check prepared food storage temperature. Track preparation times on labels. Verify discarding of expired items.

Frequency: Every shift.

Corrective Action: If prepared foods held above 4°C longer than 4 hours, discard. If shorter duration, return to refrigeration. Reinforce labeling procedures with staff.

Implementing Daily Temperature Monitoring

Temperature Log System Create a simple daily log form listing: date, time, location (Cooler 1, Cooler 2, Freezer), temperature reading, staff initials. Include space for corrective actions.

Example log:

Date: June 15, 2026 | Location: Main Cooler | Time: 8:15am | Temperature: 3.2°C | Staff: Maria | Notes: Normal | Action: None

Date: June 15, 2026 | Location: Freezer | Time: 8:20am | Temperature: -17.5°C | Staff: Maria | Notes: Normal | Action: None

Provide calibrated thermometers for each unit. Calibrate against a standard thermometer quarterly (€5-€10 per calibration).

Frequency: Once Daily Conduct temperature checks at the same time daily (recommend 8-9am before opening, when equipment has stabilized). Record temperature of each refrigeration unit, freezer, and ice machine. Takes 5 minutes total.

Out-of-Range Temperature Response If temperature exceeds 4°C or drops below 2°C: 1. Check again immediately (may be sensor issue) 2. Investigate cause (door left open? Thermostat stuck? Compressor failure?) 3. Document finding: "Cooler at 5.1°C on June 15 at 8:30am. Door was propped open for cleaning. Closed door. Rechecked 9:15am: 3.8°C. Normal operation restored." 4. If issue persists, contact technician 5. For temperatures significantly out of range (above 5°C), move high-risk foods (milk, prepared items) to backup cooler immediately 6. Store and attach log to cooler or in management folder

Supporting Documentation

Equipment Calibration Records Keep proof that thermometers are calibrated. Most cafes use one reference thermometer and compare others against it quarterly. Document: date, reference thermometer reading, compared equipment reading, variance, action taken (adjust or replace). Store 3 years minimum.

Maintenance Records Document all equipment maintenance: dates, technician name, work performed, result. Example: "Cooler compressor serviced June 1, 2026 by Kostas Refrigeration. Replaced seals. Temperature stabilized to 3.5°C. Service cost €80."

Staff Training Records Document that all staff understand HACCP and their responsibilities: "All staff trained on HACCP procedures June 2026. Training covered: temperature monitoring, handwashing, equipment cleaning. Staff: Maria (signed), Nikos (signed), Sofia (signed)."

Creating Your Written HACCP Plan

Summarize your HACCP system in a 2-3 page document for EFET:

"Greek Cafe Manager HACCP Food Safety Plan Identified Hazards: Biological (pathogenic bacteria), Chemical (cleaning supply contamination), Physical (glass/metal) Critical Control Points and Controls: 1.

Monthly and Quarterly Reviews

Monthly Review Pull together all temperature logs. Look for patterns: Is one cooler consistently running higher? Are temperature extremes occurring during busy periods? Are corrective actions being documented? Are there gaps in daily monitoring (missed days)? Address issues: if one cooler runs high, schedule maintenance. If monitoring gaps exist, retrain staff.

Quarterly Review Conduct internal audit against HACCP plan. Are all documented procedures being followed? Are staff demonstrating proper handwashing? Is equipment being cleaned per protocol? Are training records current? Document audit findings and any corrective actions needed. Update HACCP plan if procedures change.

Frequently Asked Questions

What's the difference between HACCP and EFET compliance?

HACCP is the food safety system (how you prevent hazards). EFET is the Greek agency enforcing food safety regulations including HACCP compliance. You implement HACCP; EFET audits that you're doing it correctly.

How detailed should my HACCP plan be?

2-3 pages is typical for a small cafe. Must cover: identified hazards, CCPs, critical limits, monitoring procedures, corrective actions, verification methods, and record-keeping. EFET wants clear, specific procedures—not vague intentions.

What if temperature drops significantly overnight?

Document the finding and investigate. Most likely causes: thermostat malfunction, door left open, or sensor error. If confirmed malfunction, contact technician. If foods were above safe temperature, potentially discard high-risk items depending on duration and foods affected.

Can I use digital temperature monitoring?

Yes. Digital thermometers with data logging are acceptable and increasingly common. Still require calibration and documentation. Some smart systems send alerts if temperature goes out of range.

What corrective action is needed if daily monitoring is missed?

Catch-up: take reading as soon as noticed and note "Delayed monitoring—equipment operating normally." Document why monitoring was missed (illness, emergency). Review procedures with staff to prevent future gaps. Repeated missed monitoring is an EFET violation.
