Singapore's SFA requires HACCP-based food safety management for licensed food businesses. Comark's temperature data loggers make compliance practical — here's what records you need, which models work for Singapore's food sector, and how to avoid the most common audit failures.
If you run a food business in Singapore — whether you're operating a hawker stall, catering company, central kitchen, food manufacturer, or supermarket cold chain — the Singapore Food Agency (SFA) expects temperature monitoring as a core part of your food safety management system. For licensed businesses required to implement HACCP (Hazard Analysis and Critical Control Points), temperature is usually the most important critical control point (CCP). Comark food temperature loggers are designed specifically for this application — and they're the tool of choice for food businesses that take HACCP seriously rather than treating it as a paperwork exercise. Browse our Comark range and temperature measurement instruments to see the full lineup.
Let's get the compliance picture clear first, then look at how the right tool makes it practical.
SFA's HACCP requirements apply to food manufacturers, caterers, and food service establishments based on their licence type and the risk level of the food they handle. The temperature critical control points that SFA focuses on are:
Key Stat
According to SFA's food safety statistics, temperature abuse during storage and preparation is consistently among the top three contributing factors in Singapore food poisoning incidents. Documented temperature control that prevents abuse also protects businesses from liability in the event of a food safety incident.
A spot-check thermometer — even a calibrated, accurate one — only tells you the temperature at the moment you checked. It tells you nothing about the three hours between the last check and now. In a commercial refrigerator that runs a defrost cycle every 8 hours, the interior temperature spikes briefly to 8–12°C during defrost before the refrigeration system restores the setpoint. If your spot-check thermometer records 2°C at 9am and 3°C at 5pm, your HACCP record looks fine — but the defrost spike at 2pm that pushed chilled food above 4°C for 45 minutes is invisible.
A data logger records every 5, 10, or 15 minutes continuously. The defrost spike shows up clearly. More importantly, you have a complete record that demonstrates your cold room maintained specification — or that it didn't and you took corrective action. For an SFA audit, continuous logger data is vastly more convincing than a clipboard of spot-check readings taken twice daily.
Comark has been manufacturing food industry temperature measurement equipment for over 60 years, with a specific focus on HACCP-compatible solutions. Their Singapore-relevant range covers several application types:
The most practical solution for Singapore's small to medium food businesses — hawker central kitchens, caterers, food courts, and restaurants. These compact devices sit inside the cold room or display case, record temperature at programmable intervals, and download directly to a PC via USB for spreadsheet or dedicated software analysis.
Key features for Singapore use:
For food businesses with multiple cold rooms, a central kitchen with cold stores and processing areas, or any application where you want continuous real-time monitoring without physically entering each space, Comark's wireless RF systems provide automatic centralised monitoring.
The RF300 system uses 2.4 GHz wireless sensors in each monitored location, transmitting to a central gateway. The gateway connects to a PC running Comark's monitoring software, which logs all data, generates alerts when any location exceeds its temperature threshold, and produces compliance reports automatically.
For a cold chain operation with 6–10 cold rooms and a blast freezer, a wireless system pays for itself quickly in eliminated labour for manual checks and automatic documentation. For HACCP record completeness, it's transformative.
For cook temperature verification at the CCP (checking that poultry has reached 74°C core temperature), a fast-response, waterproof probe thermometer is required. Comark's N7000 series is IP67 rated, dishwasher-safe, and provides 0.1°C resolution with response times under 5 seconds in most food applications.
These must be calibrated — a thermometer that reads 73°C when the actual temperature is 68°C creates a food safety hazard while generating records that show compliance. Our SAC-SINGLAS calibration service calibrates food thermometers with traceable certificates.
Pro Tip
Singapore's humid ambient environment causes condensation on loggers moved from cold rooms to ambient. Never download data immediately after removing a logger from a freezer — allow it to warm to room temperature for 15 minutes first to prevent moisture damage to the USB port. Comark's higher-spec loggers are IP65 rated and more resistant to this, but good practice helps all equipment last longer.
SFA's HACCP records for temperature CCPs must be sufficient to demonstrate that control was maintained. At minimum, each record should include:
Comark's data logger software automatically generates reports in a format compatible with most of these requirements. The automated alarm and corrective action log (requiring a typed acknowledgement when an alarm occurs) covers the corrective action documentation automatically.
Watch Out
A common SFA audit finding: temperature records exist, but the thermometer or logger used has no calibration certificate. A measurement without verified accuracy cannot demonstrate that the CCP was actually controlled — it only shows that someone measured something. Ensure all HACCP measurement devices are calibrated and the certificates are filed with the HACCP records.
SFA's HACCP guidelines state that temperature measurement equipment must be accurate, maintained, and calibrated. For food businesses, calibration certificates from our SAC-SINGLAS accredited lab provide the gold-standard documentation.

Comark food temperature loggers make the HACCP compliance burden genuinely lighter — automatic records, alarm documentation, and PDF reports that satisfy SFA auditors without manual spreadsheet maintenance. For Singapore's food businesses operating in one of the world's most food-safe regulatory environments, the combination of Comark's purpose-built hardware and traceable calibration from our SAC-SINGLAS lab is the practical HACCP solution that holds up under audit. Temperature control is not optional in food safety — the question is whether your records are good enough to prove it.
What temperature monitoring is required under SFA's HACCP requirements in Singapore?
Under the Singapore Food Agency's licensing requirements, food businesses handling high-risk foods must implement a HACCP-based food management system. Temperature monitoring is a critical control point (CCP) for cold storage (≤4°C for chilled, ≤-18°C for frozen), cooking (minimum internal temperatures of 70°C or higher depending on the food type), and hot holding (≥60°C). Records of temperature monitoring at these CCPs must be maintained and available for SFA inspection.
What is the difference between a temperature data logger and a temperature thermometer?
A thermometer gives you an instantaneous reading at the moment of measurement. A data logger records temperature continuously at a programmed interval (e.g., every 5, 15, or 30 minutes) and stores the data for download and review. For HACCP compliance, continuous data logging is far more robust than spot-check measurements — it provides an unbroken record of temperature throughout storage, transport, or processing, not just the moment a quality check was performed.
Do I need a calibrated thermometer for HACCP compliance in Singapore?
Yes. SFA's HACCP guidelines require that temperature monitoring equipment be accurate and calibrated. Thermometers and data loggers used at critical control points should be calibrated at regular intervals and records of calibration maintained. For SFA audit purposes, calibration certificates from a recognized calibration service provide the documentary evidence of accuracy.
How long must HACCP temperature records be kept in Singapore?
SFA requires food safety management records, including temperature monitoring records at critical control points, to be retained for a minimum of 1 year. However, for businesses also complying with ISO 22000 or exporting to markets with longer retention requirements (e.g., EU, USA), retain records for 2–5 years depending on the product category and the regulatory requirement of the export market.
Can a Comark RF temperature logger work in Singapore's food cold rooms?
Yes. Comark's RF300 and RF500 wireless systems use 2.4 GHz radio frequency transmission to relay temperature data from sensors in cold rooms to a central gateway and data management software. These systems are designed to operate in temperatures as low as -40°C, making them suitable for blast freezers and frozen storage facilities. The wireless transmission eliminates the need to physically enter a cold room to download data, improving both hygiene and efficiency.
