A key focus of Women in Food Safety is to highlight female leaders in various food safety career paths. This month we have the privilege to speak with Jennifer McEntire, Ph.D., SVP of Food Safety & Technology at the United Fresh Produce Association, who has a storied career combining hard-core science with policy development that is risk-based, science-based and pragmatic to implement.

As many know, I am a lawyer. With that, I feel compelled to disclose the following disclaimer: I have worked alongside Jennifer as a business and industry colleague, and I consider her one of the most impressive, influential yet humble people I have ever met. Given my first-hand knowledge of her professional and personal contributions and unquestionable character, our conversation quickly dove deep into candid discussions about her career path, focusing on her passion for policy and seeing trade associations as a vehicle and a collective voice to influence and shape policy. Jennifer’s insights on being female in our industry are truly enlightening. See for yourself.

Melanie Neumann: Can you please summarize your career path to your position today, or what I like to consider your “path to produce?”

Jennifer McEntire, Senior Vice President, Food Safety and Technology, United Fresh Produce Association

Jennifer McEntire: I grew up in Long Island, which is not exactly the epi-center of agriculture. I liked science but didn’t want to be a doctor. At the time the University of Delaware looked through all the postcards (yes, I’m dating myself!) of kids interested in science and sent packets of information about the food science program. It was the best thing that could have happened to me! It was a small program; there were only four people in my graduating class; so I really couldn’t fly under the radar. I am the first person in my family to go to a university and I had no idea what graduate school was. Tons of people took me under their wing. I was able to do food safety research as an undergrad, which allowed me to jumpstart my graduate education. I truly had no plan to get a Ph.D. I wanted to work! But during my freshman year of college my biology professor nonchalantly mentioned that graduate students in sciences get paid to go to graduate school. I was like, WHAT?!? It was a no brainer. The more I got involved with the food science clubs at UD and at Rutgers (where I got my Ph.D.) and the more I networked with professionals at regional meetings of the Institute of Food Technologists (IFT), the more I learned about the breadth of career options. I knew I didn’t want to be an academic so I didn’t do a post doc. (That said, I love mentoring, training and professional development, and have been lucky to weave it into every job I’ve had). I liked the product development side but thought I might get bored in one company. Although I am an introvert, I like hearing different perspectives and meeting very different kinds of people. Once I saw the nexus of disciplines and perspectives in Washington D.C., I was hooked. Although I’ve always worked in the general food safety arena, at IFT, The Acheson Group, GMA, and now at United Fresh, each role has been vastly different and I keep realizing how much there is to learn.

Neumann: Much of your career centers around trade associations. Why did you choose this sector over others in the food industry?

McEntire: Trade associations provide me with a vehicle to fulfill my goal of being an “Ambassador for Science.” I was fortunate to have a rare opportunity as USDA National Needs Fellowship at Rutgers, which allowed me to work for both FDA and a trade association, the National Food Processors Association (NFPA), towards the end of my Ph.D. program. I quickly fell in love with the buzz of D.C. and realized this is where the action is—the intersection of science, law, policy and the power of networking. I accepted a permanent position with IFT in their D.C. office after graduation to continue my quest to learn more about the inner workings of D.C. as well as provide IFT with an even greater voice based on science. I’ve now been in D.C. over 20 years. I understand why it turns some people off, but I love it. I’m constantly meeting new people and really love being a conduit between the industry, the regulators, policy makers and others.

Neumann: From the start it seems like you were fortunate that you were able to start your career at the strategic level, or “forest”. What advice would you give someone who perhaps had a more typical start in a technical role, or “trees”, and wants to gain strategic roles in the industry?

McEntire: From the get-go at IFT I was pulling together expert panels, meaning I was constantly around experts, which was exhilarating for someone in her 20s. But I realize that’s atypical. Part of what I love about working in associations is the ability to connect people. Those are opportunities exist at every level. “Seek out, don’t sit back.” This advice applies equally personally and professionally. If you want to understand how your current technical role supports your food safety strategic plan or corporate strategy, seek out who you believe can answer your question and ask. If you have a suggestion to improve your role or an aspect of your food safety program, speak up. If you would really like a mentor but no one has assigned you one, seek them out. What worked for me early in my career and what still does today is that I study people. I may be at a conference listening to a presenter, and I will ask myself “what do I like about their style of communication?” or “What about them is capturing my attention enough to listen to them?” Adopting certain aspects you like, (or dislike and want to be sure you avoid doing!), and adapting your style to incorporate them is a great way to professionally evolve. This said, don’t lose yourself or your own style by impersonating or assimilating too much of others’ ways. What sets you up for success is designing an approach that leverages your personal strengths and is unique to “you”.

A key message from my perspective is not to sit back and wait for the career you want. Rather, my advice is to proactively seek out opportunities, answers to questions and relationships with others in your company and/or in the food industry that you believe you would benefit from interacting.

Neumann: Have you experienced challenges in being a female in this space?

McEntire: Subtle challenges, sure. In my case I feel it was more my age than my gender that I needed to overcome. But specific to gender, my biggest perceived challenge was the pressure I placed on myself. These self-imposed challenges were expectations I put on myself in part due to societal expectations or roles I thought I needed to play as a mother, partner, community member and as a professional. I expected to perform at 100% at all times in every role, and over time realized that isn’t sustainable, or even sane, to expect of yourself!

As a younger professional I knew that I had hurdles to overcome when I walked into a room (sometimes I still feel that way). What I learned over time is how the power of data helps in situations where, real or perceived, I felt that my audience wasn’t tuning in to me as much as others in the room. That is when I became even closer friends with data and gave thought about how to construct and communicate my key points. I learned that with sound facts based on sound science to support my position, I was the most informed person on that topic in the room, and my ability to successfully negotiate and convince the other stakeholders increased considerably. This was especially true when I tied the data to tell a compelling story. The most effective, influential professionals I have encountered, some I consider my mentors, are master storytellers—relying on facts when presenting their case in a way that tells a story.

Neumann: Do you have any additional insights or advice to share with women in food safety regardless of where they are at in their career journey?

McEntire: If you love what you do, and you do it well, be bold and be brave. So many people, male and female, saw a potential in me I wasn’t even aware of, and they made serious investments in me. I find that in the field of food safety, that’s pretty common. We are a friendly bunch! So reach out and start talking to people. You’ll be amazed how many people will chat with you at a meeting or return your email.

One thing that concerns me, and I don’t yet have enough anecdotal data to tell if younger women are more prone to this than their male counterparts, is this expectation that they have to know their full career path from the time they are 18 years old. They seem to put a lot of pressure on themselves to “have it all figured out”. As someone who is “Type A” and very much a planner, I can confidently say that no part of my career has been planned. I never ever could have predicted that I would wind up where I am today. I maintained an openness to new opportunities, listened a lot, and considered new information that became available. I did my best to not burn bridges, while at the same time sticking up for myself and for others. Food safety is hard. It takes a thick skin and at this point in my life I have to say that having a network of women food safety colleagues as a support system makes some of the more stressful days much easier.

Rare and old whisky can be a significant investment, except for when they are fraudulent. One report found that about one-third of rare whisky (and wine) may be fake, leading to $1.5 billion in losses in Europe alone. A handheld device is now able to detect fraudulent products rapidly. The analysis method involves electrodes that analyze characteristic groups of molecules that can be found in the real product. The device then checks the results against real whisky samples from a database.

The Crossroads of Strategic, Tactical, and Operational Planning in Food Safety Culture

By Jill Stuber, Tia Glave
No Comments
Jill Stuber, Tia Glave

With the release of new food safety and quality regulations or requirements—such as food safety culture—there can be a flurry of action to understand how a food company’s systems and processes should change to meet the new regulations or requirements. The typical response begins with the phrase “we need a plan.” For many, “we need a plan” translates directly into action. It’s the phrase that drives people forward to start “doing” in the hopes of reaching the desired outcome.

A quick-to-action organization that skips the planning represents the classic mistake in understanding strategy, tactics and operations. These organizations will find that they are constantly spending time and money re-doing action steps or correcting errors they have made. This leads to a culture of confusion, frustration, anxiety and resistance, the opposite of what we want in any culture.

As food companies are trying to understand and implement a “food safety culture” into their organizations, it is the perfect opportunity to take a step back and review the differences between strategic, tactical and operational work. All three are essential for food safety and quality programs and building a strong culture of food safety.

Consider this. Only 22% of people believe their organization has a clear direction.1

Join Jill Stuber and Tia Glave as they discuss “What I Wish I had Known Early in my FSQ Career” during the 2021 Food Safety Consortium Virtual Conference Series on Thursday, November 4Many reasons contributing to the 22% are reported; however, most companies generally do not spend enough time in the planning phase to build a strategy and develop the team to implement that strategy. Most people are rewarded for being busy with metrics such as % efficiency, % yield, and sales, not necessarily for successful change management, which can signal trouble ahead. Building clear plans around food safety culture will energize your team to participate in the planning and come along on the adventure.

Building clear plans start with understanding how strategic, tactical and operational plans support organizational direction. Let’s begin with having clarity around each term as they are often used interchangeably and often outside standard definitions. Consider these practical definitions:

Strategic (The HOW and the WHY): Designed with the entire organization in mind, typically at the highest levels of the organization, often with external support. Focused on three, five, 10 years out.

Tactical (The WHAT): Translates strategic ideas into a framework for the operational implementation. Focused on the next 12 months.

Operational (The DO): Specific actions and steps taken by front-line managers and team members to realize the tactical plans. Focused on today and this week.

To demonstrate a misuse of the terms, consider the following: A company is implementing new food safety and quality management software. Before implementation, top senior leaders choose an aggressive launch date and start working with a consulting firm and their leadership team to identify the software that works best for their organization. A software is chosen, and then it’s a race to implement the software before the launch date. Once the company realizes that they are not going to meet the launch date due to the implementation schedule taking longer than expected, the launch date is pushed back a month. The month passes, and even though implementation is underway, the company is not ready to launch. The top senior leaders decide to stick with the modified launch date. Months later, the company is still not using the software the way they had planned.

What went wrong? Critical parts of the strategic and tactical work were not done upfront, which led to poor operational work during the implementation phase. The company did a great job working through options with other leaders and choosing the best program; however, they failed to use that vision to evaluate the resources needed for implementation and then translate that vision into tactical steps to get a realistic timeline for launch. Unfortunately, this lack of planning leads to resources feeling overworked and frustrated.

When thinking about food safety culture (or any culture), having your team members feeling overworked and frustrated will only hurt. We have found that following these macro steps to navigate each phase ensures that organizations successfully develop and implement new strategies that will lead to energized and supportive team members.

1. Create a Vision (Strategy)

How and where does food safety culture align with the organization’s purpose and mission? The food safety culture strategy requires a story around what it is, why it is important, and how it supports the organization. We like to call it the Blue-Sky Vision encouraging people to think big—the sky’s the limit! The vision will evolve into a strategy around food safety culture that stems from activities like honoring what is working well in the organization, listening sessions that gather the voice of your team members, to engaging with external stakeholders to broaden perspectives. The vision should align with purpose and values. After all, “When the WHY is clear, the HOW is easy”— Unknown.

2. Evaluate Skills and Resources (Strategic and Tactical)

What in the organization, such as people, systems, and processes, will serve the Blue-Sky vision in the future? What additional skills and resources are needed? To build an organization to this point, many factors are likely working well and may serve as the foundation for moving forward. Yet, things must be released to get to the next level to make way for the new. For example, will the Food Safety Manager be the champion of food safety culture? If yes, what current tasks must they pass along to others or stop to fulfill the champion role? The practical side of allocating money and time is also critical at this step. The evolution of skills and resources to reach Blue-Sky won’t happen without intentional support.

3. Understand Incentives (Strategic and Tactical)

What’s motivating and encouraging team members in every function at every level to work toward the Blue-Sky vision? What incentives may pull team members off track and conflict with the Blue-Sky vision? Be careful here! There have been many discussions about incentivizing food safety behaviors where it is detrimental. An example is reducing the number of holds. A key metric around reducing holds may simply reduce communication that holds are needed, thus letting defective products out the door. Focus on “the why” and incentives team members that exemplify behaviors that support it.

4. Build Your Action Plan (Tactical)

Unless you like herding cats, you need a clear plan that outlines actions for each function and role. Without a detailed plan, everyone will work with their best intentions instead of the vision’s best intentions to move forward. This could be your individual or team’s 4-Quarter Plan or 30-60-90 Action Plan.

5. Implement Your Plan (Operational):

Hellen Keller says it best with “Ideas without action are useless.” If you’ve done all the work in the phases above, the fruits of that labor will be observed in the day-to-day work of each team member. What changes are related to procedures? How is time allocated to have a real-time discussion around food safety behaviors? How will relationships be fostered each day to build transparency and engagement?

By understanding the phases related to change management, evaluating and improving your organization’s food safety culture will be a joyous adventure. Engaging team members using catch-ball, a lean concept, at every single phase will align and energize the entire organization on your way to the Blue-Sky Vision of food safety culture that honors your organization, team members and clients.2

Fish and seafood mislabeling is rampant in Canada, according to a report published earlier this year by Oceana Canada. To address the rising concerns of Canadian consumers, the Canadian government is finally consulting with the seafood industry on traceability from boat to plate. These suggestions are supposed to tackle mislabeling, illegal fishing, sustainability issues and unregulated fishing. Even restaurant owners and chefs have called Congress for action.

Produce from specific countries of origin, such as olive oil or walnuts from a famous region, can achieve top prices in the marketplace. Fraudulent declarations of origin are causing millions of dollars of economic harm every year. Such fraud can be detected by investigating the oxygen isotope ratio, a costly endeavor until now. A newly developed oxygen isotope ratio simulation model eliminates the costly collection of reference data and allows a timely and cost-efficient region of origin determination of a wide array of plants.

The popularity of “natural” foods with consumers has increased exponentially over the past decade or two. While the term “natural” on a food label is not formally regulated by the FDA, “natural flavors” have been defined in the Code of Federal Regulations Title 21 as flavoring constituents derived from a naturally occurring source, such as spice, fruit, vegetable, herb, leaf and more. “Natural” flavors/aromas have specific spectroscopic fingerprints versus synthetically produced volatile organic compounds. This method combines gas chromatography and isotope ratio mass spectroscopy (GC-C-IRMS) to determine whether a fruit aroma is naturally or synthetically-derived, and can be used to build a database of natural flavors.

The Face of Food Safety: How Do You Look?

By Jill Stuber
No Comments
Jill Stuber, The Food Safety Coach

What does food safety look like? As we enter the New Era of Smarter Food Safety, the elements around food safety behaviors, beliefs and attitudes are a bit elusive, making them challenging for the industry to define. For years, companies have provided messaging around food safety to clarify what food safety should look like for their team members. In reality, most of the statements are around the outcomes organizations want to see.

For example:

  • Food Safety and Quality are our number one priority.
  • We strive to meet and exceed all food safety & quality standards.
  • We are committed to producing high-quality, safe food.
  • Food safety is everyone’s responsibility.

While these messages may provide clarity around the organization’s beliefs and/or intended outcomes around food safety, how do these messages translate into how food safety behaviors, beliefs, and attitudes show up on a day-to-day basis?

A quick internet search will provide a list of companies that have adopted best-in-class food safety culture practices with top leaders championing and modeling what that means through daily conversation, decision making, etc. Not all companies share that success story, and top leaders may find or refine their organization’s path around food safety culture. As top leaders are taking the time to create strategic plans for food safety culture, how can the behaviors, attitudes, and beliefs around food safety be modeled for all to see?

It reminds me of an experience with one of my teams and our journey around championing food safety and quality. Shortly after being promoted into leading our FSQ function for multiple facilities across our organization, I soon found, with no surprise, that each facility had its own FSQ microcosm. As with anything, parts of the microcosms were good, and some, not-so-good. The FSQ Managers had completely different personalities, training and experience blending with and creating resistance in the microcosm to add to the mix.

Join Jill Stuber and other food safety experts for a discussion about industry professional development, training and mentorship on November 4, during the 2021 Food Safety Consortium Virtual SeriesOur team focused on creating consistency in our team’s practices and organizational systems for food safety and quality. After several months together, it was clear the goal would require more than developing one version of the truth with documents; it would also require consistency in how the FSQ Managers “showed up” each day. Thus, we keyed the term the “Face of Food Safety,” which embodied our expectations around how we would each exhibit behaviors, attitudes, and beliefs around our role to support our Food Safety & Quality systems. For us, this insider term solidified our shared passion and belief that food safety culture started with us.

What led us to the conclusion that we had to step into the Face of Food Safety role given food safety culture is supposed to start at the top? Several pieces of evidence led us to this conclusion.

  • The term “Food Safety Culture” wasn’t even mainstream for top leaders to start discussing food safety culture. We recognized we needed to continue the food safety campaign across the organization using our team and our voices.
  • Our FSQ Leaders were already the go-to for food safety. Like many companies, when the food safety auditor walked in, they were taken directly to the FSQ Manager. If anyone in the organization were asked about who to talk to regarding food safety, they would direct people to the FSQ Manager. It’s no different than if someone asks about a financial report, they were likely led to the accounting department.
  • Our FSQ Leaders had the most technical training, even if not formal, to understand the practices and behaviors around food safety and should be already collaborating and championing best practices throughout the organization.

As we started on our quest to define the Faces of Food Safety further, we had some factors to consider impacting our approach.

First, our FSQ Managers came in all shapes, sizes, and personalities. Some had high levels of formal training, and others had very practical experience. Some worked in the industry for eons, and others had less experience. Some were more natural leaders, and others were not, and personality tests showed we had a wide range in our team!.

Next, our FSQ Managers had specialized training regarding scientific methods to more effectively identify risks, guide solutions, and ultimately create and implement programs that consistently delivered safe food. However, besides the annual human resources training on conflict resolution or getting along, the FSQ Managers had no formal training in human behavior to fully understand elements of the human psyche that shape what people do.

Finally, we faced a standard human limitation—our ego. With serving others, our egos would have to take a back seat to allow the space to recognize our behaviors, our judgments and actions that didn’t align with the Face of Food Safety.

As I look back at work we did together to step fully into being the Face of Food Safety; there are three main areas we focused effort that minimized any factors around skills, experience or personalities yet allowed us to move forward with our quest.

1. Being available and approachable

  • Instead of sitting in meetings, running reports, and being “busy,” we focused on spending time with team members on the floor with FSQ Team Members and others to see what worked well, what didn’t work well, and in-the-moment coaching. The team evaluated workload capacity and incorporated these routine interactions into standard work to create capacity for this. No longer was spending time on the floor to talk with team members something we just hoped we’d get around to doing or only do during an investigation. While we still had copious amount of other work, we shifted our priority.
  • We spent time developing trust across our team to open doors to conversations that were previously off-limits. For a team that had rarely been physically in the same place at one time, our every-other-month in-person events and daily huddles that, at first felt like micromanaging, became the standard of how our team worked toward alignment and team building. These types of routines provided a foundation for conversations that started with “How do you think you came across in that email?” or “I know you didn’t intend to sound demanding, but some people had ruffled feathers”, or “Your serious face may send the message you don’t want to be bothered.”

2. Helping others help themselves

  • In the olden days, issues could be dropped like hot potatoes into the FSQ office for them to spearhead investigations, paperwork, and the like. People would come to the FSQ Managers for answers when often, the answers were already available to them. It took effort from FSQ Managers to provide guidance, re-direct and coach so others could join in owning parts of food safety and quality related to their work.
  • We were changing our attitudes that we had to be involved in everything. When we began helping others help themselves, it also gave us the freedom to let go and work in our own lane.

3. Being known for championing food safety & quality both from a policy standpoint but also being practical

  • Policies and procedures are fantastic tools to align practices. Even with the best-written documents, there are gaps and unforeseen events that challenge systems. In those moments, our team worked diligently to align on when policies and procedures had to be upheld versus when we would adjust (and update documents) to capture the practical nature of hiccups that happen in manufacturing. We didn’t want a practice to be okay in one facility but not another unless there was a very defined reason, so it wasn’t chalked up to personal preference. It took personal commitment to Our commitment to holding the line for each other.
  • Our team was relentless in talking about food safety and quality at every chance we had and related to other areas.

As leaders, our focused, aligned manner that welcomed collaboration and conversation was a cornerstone for being the Face of Food Safety. Using the three areas discussed in this article, we provided clear messaging and support to champion the food safety culture we wanted to see. While not every day was a utopia, our attitude shift and teamwork offered many more days of fulfillment from meaningful work than we had previously experienced and it made an impact for others.

An especially perfidious type of edible oil fraud is the dissolution of inedible plastic material, such as polypropylene or polyethylene packaging material, in hot cooking oil during the frying process. This is supposed to prolong the shelf life and the crispness of deep-fried snack food, not surprisingly with serious health implications. Attenuated total reflectance fourier-transform infrared spectroscopy (ATR-FTIR) in combination with principal component analysis (PCA) provides a straightforward method to analyze samples directly with minimal preparation, to detect polymers in palm cooking oil, as done in this study.

Will a New Method of Freezing Foods Improve Food Quality and Food Processing?

By Emily Newton

Emily Newton, Revolutionized Magazine

As the world veers on the edge of serious climate trouble, it makes sense for companies to collectively start looking into greener and more efficient alternatives. While research is ongoing, every so often, there’s a win that can make a huge difference if and when it is implemented. That’s precisely what’s happening with cutting-edge frozen food and processing technologies, thanks to scientists from the University of California-Berkeley who conducted a study on the concept with the USDA’s Agricultural Research Service.

It came at just the right time, too, as both freezing foods and standard food processing technologies have a rather large energy footprint, with extensive carbon emissions. Globally, those levels have to come down or the results will be disastrous. This new method, proposed by researchers, could reduce the global energy consumption of the frozen foods industry by up to 6.5 billion kilowatt-hours per year. Just to put that into perspective, it is the equivalent of removing one million cars from the road, and keeping them out of regular operation.

Called isochoric freezing, the method essentially involves placing foods in a sealed and rigid container. The storage container, made of hard plastic or metal, is then filled with liquid—like water—and frozen. The catch is that not all of the liquid in the container is frozen, so the food does not turn to solid ice. Only about 10% of the volume freezes during the process, and as long as the food remains within the hardened ice, crystallization will not happen. In addition, pressure that builds up inside the container naturally prevents the ice from expanding.

Isochoric freezing also has implications for fresh foods that are significantly affected by standard freezing techniques, such as small fruits, vegetables (i.e., tomatoes and potatoes), and even some meats.

The best part is that this method can be deployed “without requiring any significant changes in current frozen food manufacturing equipment and infrastructure,” according to USDA food technologist Cristina Bilbao-Sainz.

Why Is Icochoric Freezing Better?

Freezing foods may be a quick and relatively accessible way to preserve them, but many chemical changes happen during the freezing process as well as when those items thaw. Some foods deteriorate when frozen, just at slower rates. What’s more, depending on when and how you freeze or store those items, the composition may change during the entire process.

Some frozen products may develop a rancid smell or taste, after being oxidized or exposed to air. Others may see texture or size changes, and moisture loss at any time (or poor packaging) can result in freezer burn.

A lot of these same problems do not occur with isochoric freezing because the items are not frozen solid. Even more promising is that the new method also improves the quality of frozen foods, boosts safety, and reduces energy use. And during processing it actually kills microbial contaminants.

“The entire food production chain could use isochoric freezing—everyone from growers to food processors, product producers to wholesalers, to retailers. The process will even work in a person’s freezer at home after they purchase a product—all without requiring any major investments in new equipment,” said said Tara McHugh, co-lead on the study and director of the Western Regional Research Center in a USDA press release. “With all of the many potential benefits, if this innovative concept catches on, it could be the next revolution in freezing foods.”

Making the Discovery

Boris Rubinsky, a UC-Berkeley biomedical engineer and co-leader of the project, developed the freezing method while trying to cryopreserve tissues and organs that were designated for use during transplants. The goal was to better preserve these items, under more optimized conditions, with a minimal quality loss after thawing.

While this certainly does have major implications for the frozen foods, cold storage, and food processing industries, it can also be used elsewhere. For example, areas like medicine, science, or space travel can all benefit.

It may be some time before the technology is ready, but the research team is now working on developing commercially viable options, to match modern industry needs.

Will It Lower Carbon Emissions?

If the technology, and method, are adopted on a wide scale, it could vastly lower carbon emissions across many fields, and it may even lower emissions of consumer applications, too. Imagine applying isochoric freezing on a smaller scale, at home, to better preserve leftovers, frozen meals, and much more.

Of course, it will be interesting to see major organizations adopt this method, if and when the resources are available. The food processing industry could see revolutionary reductions in carbon emissions and energy consumption in the years ahead.

When We Work Harder Together, the Sky’s the Limit

John Carter, area Europe quality director at Ferrero, has been devoted to diversity for more than 20 years. This time, it’s our pleasure to speak with him to hear his perspective on female professionals in the industry and how his male peers can help encourage a diverse environment and break unconscious bias.

His background in engineering, along with an MBA, has given him a scientific mindset when making decisions. After his first job with Campden BRI in the UK, John had positions at Kraft/Mondelez, Metro, Danone, and is now at Ferrero; in that time, he has gained tremendous food safety and quality experience. As is the case with many food safety professionals, John is proud to be part of an industry where he can use his technical knowledge to protect public health. “Food safety is not competitive; it’s a global collaboration, and a rewarding field,” he said.

John advises young professionals to avoid limiting themselves to one function. Explore different functions within a business; if you have been working within food safety for more than 20 years, you might not focus on the full scope of the food industry or food operations. To move forward into an advanced position, especially toward a senior management position, John explained that one should have a helicopter view of the business and vision. For example, moving from food safety to the quality management system, to operations is one option, allowing you to see the big picture. “Don’t hesitate to explore other functions. At Kraft, we used to say that to be a senior executive, you need to do 2, 2, and 2, meaning you need to do two countries, two categories, and two functions. Afterward, you can say you know the company,” he said.

In the future, John hopes to see at least a 50-50 ratio of male-to-female professionals, or an even higher ratio of females.

Melody Ge: What is your most important piece of advice to aspiring—as well as current—food safety professionals?

John Carter: Walk the line and find the balance. To illustrate my point, I’ll tell a story about my experience at one company involving a recall of raw milk cheese due to positive E. coli 0157. It was quite a significant issue, but no one got sick, and we had the products withdrawn from the market. One of the questions we had at that time was why we were selling raw milk cheese. Why don’t we just use pasteurized milk and cheeses? However, the reality is that, in Europe, raw milk cheese is in the DNA of some countries. It would be hard to even think about their diet without raw milk cheese. So there must be another way to manage food safety apart from just pasteurizing the milk. How do you do it? What else can you do? Where are the risks? We, as food safety professionals, must answer these questions. So walking the line between the commercial impact and the risk is crucial. Hence, the skill of the job is to know how to make the decision properly. It’s very easy to say ‘no’ to everything, but it might not be business friendly.

What’s more important is to say ‘yes’ after a thorough risk assessment—for example, ‘yes but…’ or ‘yes with a condition of …’ Every day, we are confronting this issue. The skill in food safety and quality is to give these conditional yesses. It’s based on a logical, scientific and rational assessment of risks. The partnership with the business is that they see us as an enabling function rather than a blocking function.

Ge: Let’s focus on female professionals—any particular pieces of advice for them?

Carter: Be confident! Between men and women, there is this confidence vs. competency conundrum. Typically, men behave more confidently. ‘Can you do this? Yeah, sure!’; in contrast, for women, ‘Can you do this? Oh, well let me check, I am not sure.’ They may have the same level of competence, and maybe even the women are more competent (it’s the reality). I read a book recently called Why Men Win at Work by Gill Whitty-Collins. Gill also mentioned this in her book: We shouldn’t expect men to be less confident; we should encourage women to be more confident. (On the other hand, if I look at the women in my team, typically their competency is very high!)
The other thing is to be who you are, and keep up the competency. I will use emotional behavior as an example. A female quality manager who reported to me once was criticized by a senior colleague (a male) for being too emotional. I am more critical of the colleague, not the quality manager, because I think we as male managers need to understand emotional behavior instead of removing that behavior. She is emotional for a reason. A man’s way of dealing with that emotion might be to get angry, while a woman’s way might be to shed some tears. But the root cause is the same issue and has the same action plan. Thus, it’s important to get over the differences and manage her talent—and not label it, showing this kind of emotion as a weakness. For example, I would like to believe that crying is not the point; it’s a different way of dealing with stressful situations. You need to look for the root cause of the stress and address the stress, not judge the symptoms.

Ge: Do you believe in a glass ceiling for female professionals?

Carter: I was fortunate that I had an excellent female boss at Kraft. She believed that we needed 50/50 gender equality—that 50% of plant managers should be female, 50% of country managers should be female, etc. I had a good experience at Kraft in developing and seeing many female professionals thrive. In that specific environment, I wouldn’t agree that there was a glass ceiling for females; however, I see it elsewhere for sure. In other companies, I have been thinking about how we can get more females in director levels. It is not easy to just promote at the management level because it has to be a structural change. The system change must happen. Part of what I am trying to do right now throughout my career is address the structural problem. And senior men need to be part of the solution.

On the other hand, there are many aspects to a promotion. One needs to be good, really resilient and lucky. Luck is essential, and the right time and place are important. If you are good enough and you have been overlooked, then maybe you should go somewhere else (It is that simple). I think, in today’s world, the opportunities are there, and the recognition is there. It is the right timing now to break the ceiling. Every company I have ever worked in has started to change, so now is a good time to be in that situation.

Ge: Can you share a story that has impacted you and still inspires you today?

Carter: I remember meeting someone at Kraft, and she was doing something related to IT at that time. She was managing something related to complaints and was in a position where she got to know the quality function in the company. When we had an open role internally for a quality auditor, she applied for it. I was quite surprised when she came to me, because she was not qualified from a technical perspective. But when she told me she was interested, it inspired me. I assigned her to the factory in South Africa for training, and suddenly, she moved from a desk in Munich to a factory floor to deal with the operations and team in South Africa. Of course, the factory environment is challenging, and there is no easy factory. However, she was very talented and really loved it. (It could have gone the other way, but she nailed it). Then, she returned from this assignment and became a QA manager, eventually overseeing the whole SAP QA system. Of course, this is because of her background in the IT department before the QA training. Suddenly, she had this kind of unique knowledge of something, and no one understood the computer system or QA better than her. If she hadn’t come to me in need of a change, and if I hadn’t been inspired to provide a chance to an enthusiastic person, her path may have been different. So, go for it! Once the tough times pass, you will enjoy it, and then the sky is the limit.

Ge: What’s your opinion on unconscious bias?

Carter: I am pretty excited about this topic—I think it addresses the root cause of many issues. I have been working on diversity for the last 20 years; but only over the past couple of years have I started thinking about unconscious bias. The unconscious bias part is relatively new, but I think it may help us address the root cause of many of the behavior issues that we see in today’s world. Gill also mentioned this in her book. She was a senior vice president at P&G, and until she noticed unconscious bias, she was quite happy. So, this happens to females as well as to men. You suddenly see it, and then you see it everywhere.

I can give you another example of my own. Not so long ago, in one of the companies where I have worked, there was an internal announcement about senior leadership changes. When it was announced, I saw a list of 20 names on the screen and didn’t notice that they were all men until our diversity council had a meeting to discuss this issue. The council leader pointed out that we have zero female representatives among the twenty. Wow, I was shocked! I am a man and I genuinely care about diversity, yet my unconscious bias is that I didn’t even notice that there wasn’t a female name on the list. I had to reflect. With this unconscious bias, which we can all have, we need to work harder together.

I think there is a food safety parallel: perhaps the situation is a lot like when we first addressed food fraud at the Global Food Safety Initiative (GFSI). Food fraud is a crime, and it’s possibly the oldest crime in the food industry—centuries old. Although legislation has been in place for years, it seemed that little concrete had been done about it; but after the melamine crisis in China, and various similar issues, we finally got a political imperative to address it in a systematic way. We now have GFSI guidance documents and CPOs, and we have the technology with DNA testing to guarantee authenticity. Finally, we have the tools and political will to ‘do something’ and really address the issue.

So, coming back to this topic of diversity and unconscious bias – in my opinion, this is the “food fraud” of society; it has been ongoing for a long time, and now is the time for us to make a change. We have to ‘do something’. Every company and culture has its own issues and characteristics and all cultures are different (diverse, right?) but when you have the willingness and tools to change an environment, you can take a series of steps to make that change. The time is right, but having awareness comes first.

Ge: Any last bits of advice for our WIFS group members?

Carter: I read a little book about 40 years ago, and the book’s thesis was that there are two things you need to do and have in life. One is that you need to have fun and enjoy life; the other is to learn as much as possible. In the course of mentoring many talented folks over the years, I have added two other things to this list; have patience and courage.

Patience, courage, learning, and fun! Try to live your life with those things in mind.
