This blog summarizes an article from Snack Food and Wholesale Bakery, “Advances in cold chain technology for snack and bakery warehousing and transport.” There have been significant technological advances in recent years to enable better temperature and condition monitoring, including key offerings from Emerson. Read the full article here.

In recent years, the Food and Drug Administration (FDA) has pressed for increased monitoring and documentation of refrigerator and freezer temperatures at every point along the cold chain to detect when cold storage temperatures fall out of the transported food’s safe range. Heightened awareness of foodborne illness as a serious health problem has driven advanced monitoring systems that trigger alarms and notify personnel should temperature conditions deteriorate.

However, these advanced systems are largely the domain of processing plants, warehouses and supermarkets, fixed locations where continuous monitoring and wireless data collection and processing are incorporated into an IT infrastructure — but they’re quickly earning industry-wide adoption.

When a food shipment is transferred to a truck, train or ship, accessing and documenting its temperature data becomes problematic and limited. Historically, food transport has been the weakest link in cold chain tracking. That’s why it’s become increasingly important to track temperature data on frozen and refrigerated food in transit to ensure food security and provide operators with end-to-end documentation.

This is where the latest advances in cold chain technology come in: the development of monitoring systems that include data loggers, i.e., electronic devices that communicate with sensors to collect data over time. When fully automated, they can eliminate the errors of manual tracking and recording information during transit, transmitting and storing continuous temperature data in real time.

Emerson Cargo Solutions is one of several companies working to fill data gaps during transit, with a suite of cellular monitors and loggers — GO Real-Time Trackers — which track and log the status of perishable products shipped across the entire cold chain, all in real time. Using cellular technology and the processing capabilities of the IoT, GO Real-Time Trackers can continuously transmit and log temperature and location data and send alerts from the loading dock to the shelf.

GO Real-Time Trackers are affordable, easy to use, and small enough to fit in the palm of one’s hand, making them particularly functional for tracking and logging goods in transit. Yet they also provide global visibility to shipments while transmitting temperature data to end users’ systems via the cloud and the IoT.

To use a GO Real-Time Tracker, a worker simply pulls a tab to start the device, places it in a container or trailer, and inputs its serial number into Emerson’s Oversight Exchange Data Integration app. From there, end users have access to comprehensive and automated monitoring. Logging data is encrypted for security and transmitted cellularly to the cloud and IoT for real-time processing and analysis. With either a smartphone or tablet, a user can check shipment status and generate documentation on the go. And the real-time data and documentation that GO Real-Time Trackers are capable of collecting are extensive:

  • Maps, graphs and charts of shipments with location and temperature details
  • Shipment summary reports using GO Real-Time Tracker serial numbers
  • Current product temperatures, temperature ranges and mean kinetic temperatures
  • Trip name, current trip status, location and duration
  • Total time out of cell range, above range and below range
  • Temperature graphs
  • Alarm events

End-to-end, real-time cold chain temperature monitoring and logging with GO Real-Time Trackers provide a higher level of overall security. Users can identify and fix previously unknown problem points in the cold chain. IoT connectivity and cellular communication make it possible for apps to monitor temperatures at set parameters throughout transport. And GO Real-Time Tracker documentation provides transparency, generating comprehensive reporting to comply with regulatory agency requirements for food safety.

Prevent Food Poisoning Outbreaks with FSMA and Environmental Monitoring

Symptoms of a foodborne illness outbreak

For companies involved in food handling, the potential symptoms of a food poisoning outbreak include: local or national recalls; fines; legal action; potential financial losses; and tarnished brand reputations. With this in mind, compliance with new regulations and laws regarding food safety and the use of facility-wide environmental monitoring are your best protections against these symptoms.

A serious problem

Food poisoning is a major cause of death in the U.S. According to the Centers for Disease Control and Prevention (CDC), foodborne illnesses affect 48 million Americans annually, resulting in 128,000 hospitalizations and 3,000 deaths. And in an age of 24/7 news coverage, any food poisoning outbreak can put a company under a harsh public relations spotlight. In 2015, at least 64 people contracted salmonella from tomatoes at a Mexican quick-serve restaurant. It resulted in two class action lawsuits and eroded consumer trust. A top-selling ice cream brand recalled all of its products in 2017 when 10 reported cases of listeria resulted in three deaths. In late 2018, all of the romaine lettuce in the U.S. was pulled from stores for a month while the CDC searched for the source of its e-coli contamination. The fact is, health officials, the CDC and the U.S. Food and Drug Administration (FDA) will work to track down the source of virtually all food poisoning outbreaks all the way down the supply chain and cold chain.

The risk comes from not seeing the problems

All too often, the processors found at fault had no idea they were putting consumers at risk. Like all processors, they have to balance the cost and burden of ensuring food safety while still maintaining a profitable business. But many have little way of knowing — or the data to warn them — that they were not maintaining safe handling procedures nor providing a safe environment for food safety.

FSMA: addressing the problem

With the signing of the FDA’s Food Safety Modernization Act (FSMA) in 2011, a series of regulations set out seven steps to prevent food poisoning outbreaks through prevention programs and environmental monitoring. The FSMA reflected the need for a modern, global food safety system, “a system in which industry is systematically, every day, putting in place the measures that we know are effective in preventing contamination” (Michael R. Taylor, FDA deputy commissioner for foods and veterinary medicine, 2015).

Regulations like the FSMA are often regarded as an expensive burden. But when you realize that food poisoning outbreaks cost the food processing industry $75 billion per year, investing in preventing problems rather than paying for the consequences makes FSMA compliance an economic imperative.

That’s why Emerson  has been tirelessly working to help ensure our Cooper-Atkins products and solutions are in compliance with FSMA mandates, and providing environmental monitoring systems and end-to-end data services that help control and manage food safety anywhere in the cold chain.

How does the FSMA affect you?

New laws were passed in 2016 to bolster the 2011 FSMA for both large and small FDA-registered companies. To comply, companies must:

At Emerson, we have the expertise, products and systems to help you implement fully compliant HARPC systems and controls, as well as consult on your cGMP education and training programs.  Emerson’s Cooper Atkins business specializes in advanced environmental monitoring systems.

The importance of environmental monitoring

There are many areas along the processing chain where food may be compromised. Storing, receiving and holding food-related items at a temperature that prohibits bacterial growth are required parts of your company’s HARPC plan, making integrated, wireless environmental monitoring systems a must-have.

Processing facilities that invest in integrated, wireless temperature monitoring systems benefit in numerous ways:

  • Eliminating manual labor
  • Streamlining the collection of environmental data
  • Creating custom reporting
  • Complying with new FSMA laws and FDA rulings

As a leading manufacturer of wireless monitoring solutions, Emerson offers a range of environmental monitoring systems through our Cooper-Atkins business. TempTrak Enterprise® is a facility-wide solution that can monitor an unlimited number of points in unlimited locations — all from one software platform. NotifEye® kits are affordable, streamlined and self-installed systems for more localized operations. Both are exception-based systems: they only send out alerts when preset limits are exceeded, saving time and labor while protecting your inventory and, more importantly, brand integrity.

An investment in protection

When you look at the human cost of food poisoning outbreaks, as well as the millions of dollars in recall costs and destroyed reputations, FSMA compliance and facility-wide environmental monitoring and data systems become a highly cost-effective investment. With compliance and a data trail, you can not only prevent foodborne outbreaks, but also verify compliance and protect your brand.
