Internet of Things (IoT) Tools are Indispensable Elements of an Effective Food Safety Plan
Interested on the bad side of the U.S. Food and Drug Administration?
Didn’t think so….
But if that’s your aspiration, we’ve discovered a simple way to position you at the front of the line.
Failure to adhere to Hazard Analysis Critical Control Point (HACCP) regulations can land you in hot water, as seen in warning letters amplified in publications such as Food Safety News.
A Cleveland-based seafood company that allegedly committed “numerous violations of federal regulations.”
A Massachusetts food firm that “did not follow the monitoring procedure of continuous monitoring of the product temperature to ensure minimum internal temperature” and a Vietnamese food firm for “significant ‘HACCP’ violations.”
The Internet of Things (IoT) has revolutionized various industries, including food safety, by providing innovative tools that enhance monitoring, data collection, and management.
Given the convenience and ease of use these tools provide, industry experts say there’s really no excuse to not adopt them as a key component of your internal processes.
“All food businesses should be embracing IoT innovations to optimize their operations, improve efficiency, maximize safety and drive key performance indicators (KPIs), including consumer satisfaction, loyalty and sales,” wrote Francine L. Shaw, a food safety specialist and co-host of the Don’t Eat Poop! Podcast, in a recent compliance piece for Food Safety Tech.
IoT devices play a crucial role in an effective and up-to-date HACCP program by providing real-time monitoring, automation, and data-driven insights.
Such devices enable continuous tracking of critical control points such as temperature, humidity, and other environmental conditions, which are essential for preventing food safety hazards.
By offering real-time alerts and notifications, IoT devices allow immediate corrective actions when deviations from critical limits occur, minimizing the risk of contamination and spoilage.
The integration of IoT technology also enhances data collection and management. These devices automatically log data, reducing the potential for human error and ensuring accurate record-keeping.
They can also free up your staff to focus on higher-value activities and not worry if they log the temperature of every refrigerated space every single day.
This automated data collection supports compliance with regulatory standards and facilitates easier audits and inspections.
Furthermore, the data gathered by IoT devices can be analyzed to identify trends and patterns, enabling food businesses to make informed decisions and continuously improve their HACCP plans.
These trends can also be applied to better understand the performance of a refrigeration system, allowing for preemptive service or even replacement. Many Sonicu customers share their monitoring data feed with their refrigeration contractor, who is able to both respond to alerts and more intelligently interpret the trends to spot anomalies that can prompt service before a significant failure occurs.
IoT devices also contribute to operational efficiency by reducing the need for manual checks and interventions.
This automation allows staff to focus on other important tasks while ensuring that critical control points are consistently monitored.
Additionally, the connectivity and integration capabilities of IoT devices enable remote monitoring and control, providing food safety managers with the flexibility to oversee processes from any location.
“The use of digital technologies, such as the Internet of Things (IoT), can provide real-time monitoring and analysis of food production processes, and can help to identify and mitigate potential quality issues,” wrote a group of university researchers from Romania and Norway in a 2023 study.
IoT tools play a pivotal role in implementing an effective Hazard Analysis Critical Control Point (HACCP) plan in the food industry by enabling real-time monitoring, automation, and data-driven decision-making.
