The microbiology lab will increasingly be understood as the gravitational center of big data in the food industry. Brands that understand how to leverage the data microbiology labs are producing in ever larger quantities will be in the best position to positively impact their bottom line—and even transform the lab from a cost center to a margin contributor.

The global rapid microbiology testing market continues to grow at a steady pace. The market is projected to reach $5.09 billion by 2023, up from $3.45 billion in 2018. Increased demand for food microbiology testing—and pathogen detection in particular—continues to drive the overall growth of this sector. The volume of food microbiology tests totaled 1.14 billion tests in 2016—up 15% from 2013. In 2018 that number is estimated to have risen to 1.3 billion tests, accounting for nearly half the overall volume of industrial microbiology tests performed worldwide.

The food industry is well aware that food safety testing programs are a necessary and worthwhile investment. Given the enormous human and financial costs of food recalls, a robust food safety testing system is the best insurance policy any food brand can buy.

We are going through a unique transition where food safety tests are evolving from binary tests to data engines that are capable of generating orders of magnitude of more information. This creates a unique opportunity where many applications for big data collected from routine pathogen testing can help go beyond stopping an outbreak. Paired with machine learning and other data platforms, these data have the opportunity to become valuable, actionable insights for the industry.

While some of these applications will have an impact on fundamental research, I expect that big data analytics and bioinformatics will have significant opportunity to push the utilities of these tests from being merely a diagnostic test to a vehicle for driving actions and offering recommendations. Two examples of such transformations include product development and environmental testing.

Food-Safety Testing Data and Product Development

Next-generation-sequencing (NGS) technologies demonstrate a great deal of potential for product development, particularly when it comes to better understanding shelf life and generating more accurate shelf-life estimates.

Storage conditions, packaging, pH, temperature, and water activity can influence food quality and shelf life among other factors. Shelf-life estimates, however, have traditionally been based on rudimentary statistical models incapable of accounting for the complexity of factors that impact food freshness, more specifically not being able to take into consideration the composition and quantity of all microbial communities present on any food sample. These limitations have long been recognized by food scientists and have led them to look for cost-effective alternatives.

By using NGS technologies, scientists can gain a more complete picture of the microbial composition of foods and how those microbial communities are influenced by intrinsic and extrinsic factors.

It’s unlikely that analyzing the microbiome of every food product or unit of product will ever be a cost-effective strategy. However, over time, as individual manufacturers and the industry as a whole analyze more and more samples and generate more data, we should be able to develop increasingly accurate predictive models. The data generation cost and logistics could be significantly streamlined if existing food safety tests evolve to broader vehicles that can create insights on both safety and quality indications of food product simultaneously. By comparing the observed (or expected) microbiome profile of a fresh product with the models we develop, we could greatly improve our estimates of a given product’s remaining shelf life.

This will open a number of new opportunities for food producers and consumers. Better shelf-life estimates will create efficiencies up and down the food supply chain. The impact on product development can hardly be underestimated. As we better understand the precise variables that impact food freshness for particular products, we can devise food production and packaging technologies that enhance food safety and food quality.

As our predictive models improve, an entire market for these models will emerge, much as it has in other industries that rely on machine learning models to draw predictive insights from big data.

Data Visualization for Environmental Monitoring

In the past one to two years, NGS technologies have matured to the point that they can now be leveraged for high-volume pathogen and environmental testing.

Just as it has in other industries, big data coupled with data visualization approaches can play a mainstream role in food safety and quality applications.

Data visualization techniques are not new to food safety programs and have proven particularly useful when analyzing the results of environmental testing. The full potential of data visualizations has yet to be realized, however. Visualizations can be used to better understand harborage sites, identifying patterns that need attention, and visualize how specific strains of a pathogen are migrating through a facility.

Some of this is happening in food production facilities already, but it’s important to note that visualizations are only as useful as the underlying data is accurate. That’s where technologies like NGS come in. NGS provides the option for deeper characterization of pathogenic microorganisms when needed (down to the strain). The depth of information from NGS platforms enables more reliable and detailed characterization of pathogenic strains compared to existing methods.

Beyond basic identification, there are other potential use cases for environmental mapping, including tracking pathogens as they move through the supply chain. It’s my prediction that as the food industry more broadly adopts NGS technologies that unify testing and bioinformatics in a single platform, data visualization techniques will rapidly advance, so long as we keep asking ourselves: What can the data teach us?

The Food Data Revolution and Market Consolidation

Unlike most PCR and immunoassay-based testing techniques, which in most cases can only generate binary answers, NGS platforms generate millions of data points for each sample for up to tens to hundreds of samples. As NGS technologies are adopted and the data we collect increases exponentially, the food safety system will become the data engine upon which new products and technologies are built.

Just as we have seen in any number of industries, companies with access to data and the means to make sense of it will be in the best position to capitalize on new revenue opportunities and economies of scale.

Companies that have adopted NGS technologies for food safety testing will have an obvious advantage in this emerging market. And they won’t have had to radically alter their business model to get there. They’ll be running the same robust programs they have long had in place, but collecting a much larger volume of data in doing so. Companies with a vision of how to best leverage this data will have the greatest edge.

Examining the Role of Food Safety During R&D

Research and development (R&D) is an essential starting point toward the creation or modification of new and exciting food products, processes and packaging. To ensure that a product is safe for consumption, food safety should be considered during the initial stages of a product’s lifecycle. Incorporating food safety into R&D can be tricky, as safety considerations may change the initial idea or concept of a new food product. For example, the idea of a freshly squeezed orange juice in every supermarket shelf is appealing; however, without pasteurization, that juice will not be safe for consumption, nor will it have the desired shelf life. Adding raw chopped garlic to a hummus product makes it taste great, but will it be safe for consumption after being on the shelf for a month?

To better understand how safety of new products is assured from concept to launch, I spoke with two R&D scientists about food safety considerations during new product development. The interviewees, Maria and Laura, work for the same large food manufacturer, which is located in the Midwest, in the snack foods and breakfast cereals categories, respectively. They both confirm that the R&D team follows a specific procedure during the product concept phase—one that places food safety at the forefront. The team starts by determining how the new product compares to food safety regimens already in place with other products that the company manufactures. If the product is a line extension with only a few changes to an existing formulation, the food safety concerns are likely to be low, and the food safety program already in place is adapted to meet the safety needs of the new product. However, if the product being developed is highly differentiated from other products manufactured by the company, food safety moves into a more central role throughout the development cycle.

According to Maria and Laura, the first step in ensuring food safety for a new product is for the development scientists to have in-depth discussions about the product’s formulation, ingredients and supply sources. These three aspects, along with the planned manufacturing process, are then evaluated through a hazard assessment. The hazard assessment is comprised of microbiological, quality, regulatory, stability and physical hazard assessments. Ingredients that pose food safety concerns without prior controls and process conditions are identified. The quality team determines controls for these ingredients and subsequently involves process engineers to verify that process conditions are attainable and will provide proper control for the hazards identified. A complete HAACP plan is put in place for the new product production, taking into consideration equipment cleanability and location, traffic control for ingredients and operators, and air handling systems. The hazard assessment is documented in detail and must be approved by the quality manager before production runs can begin and development can resume. Although the entire process is led by R&D, multiple other functions are involved and consulted throughout the process.

Manufacturing processes, formulation and market availability of ingredients drive the food safety of a new product, with manufacturing processes and formulation usually being the key drivers. “However, in cases like the recent shortage of eggs due to the avian flu crisis, finding substitutions for ingredients in shortage becomes an important driver for food safety,” says Maria. Laura says that at times, product formulations can change due the integrity of the ingredient or its source. In such cases, a similar ingredient from a credible source is chosen and the safety of the product is re-assessed. There are critical quality and food safety elements that must be considered in the product design phase to prevent issues later in development. When R&D professionals keep these elements top-of-mind when considering formulation and ingredient sourcing, everyone benefits—from the company to consumers.

Although consumer confidence in the safety of the U.S. food supply is slipping (11% said they were “very confident” in the safety of the food supply, down from 15% in 2013; 50% said they were “somewhat confident”, down from 55% in 2013, according to the International Food Information Council’s 2015 Food and Health Survey), the interview with Maria and Laura shows that manufacturers are putting significant effort into developing safe food products. It is equally as important for suppliers and vendors to have robust food safety programs to build strong relationships with manufacturers. Food companies have a lot to lose if a product they develop is, or becomes, unsafe for consumption. Not only can the average cost of a recall add up to $10 million in direct costs to a food company, lost sales and the impact to the company’s market value, brand reputation, and business relationships is major. Some companies never recover from the punch. Through taking the time to audit suppliers, screen new ingredients, and make robust prototypes, food companies can be more confident in the safety of their innovative new products as they go through the development process.
