Despite decades of progress in food safety, the numbers still tell a sobering story in 2025: foodborne illness continues to be a major public health challenge in the U.S. According to the latest estimates based on 2019 data and published in early 2025, approximately 9.9 million foodborne illnesses occur annually from just seven major pathogens. The question we now need to ask isn’t just why this is still happening—but what we can do differently.
Same Pathogens, Similar Numbers—Why Haven’t Things Changed?
For years, we have relied on periodic reports to understand the true burden of foodborne illness. The 1999 and 2011 studies included estimates for illnesses caused by unknown agents, while the latest report focuses specifically on seven major pathogens. This difference in scope makes a simple year-over-year comparison of total cases misleading.
The top culprits haven’t shifted much over the years. Norovirus, Campylobacter spp., and nontyphoidal Salmonella remain the dominant causes of illness, hospitalization, and even death. These three pathogens alone account for the majority of the estimated:
- 53,300 hospitalizations
- 931 deaths annually in the U.S.
Here's a breakdown of why we might see similar numbers for some pathogens despite ongoing efforts:
- Norovirus's Persistence: Norovirus is often transmitted at the point of food preparation, frequently through infected individuals who don't practice proper hand hygiene. While the food supply chain has robust controls, preventing human-to-human transmission and contamination in diverse settings remains a significant challenge. It's a pathogen that thrives on close contact and can spread rapidly.
- Improved Detection vs. Reduced Incidence: The increased use of Culture Independent Diagnostic Tests (CIDTs) plays a crucial role here. We are now simply better at identifying and reporting cases that might have gone undiagnosed in the past. So, while the reported numbers might appear similar or even slightly higher for some pathogens, it's possible that the actual incidence hasn't increased, but our ability to see it has. This is a positive development for public health surveillance, but it can create the perception of stagnation in the numbers.
- Underdiagnosis and Underreporting Remain Factors: Even with CIDTs, underdiagnosis and underreporting are still inherent challenges in estimating the true burden of foodborne illness. Many people with mild symptoms may not seek medical care, and even when they do, a diagnosis may not always be made or reported to public health authorities. The study itself uses complex methodologies and multipliers to account for these undercounts, highlighting their continued influence on the final estimates.
- The Dynamic Nature of the Food System:The food system is constantly evolving. Changes in consumer preferences, global supply chains, and even environmental factors can introduce new challenges and create opportunities for pathogens to spread. While we implement controls, these dynamics can create a constant need to adapt and refine our strategies.
- Focus on Different Areas: While overall numbers might seem similar, significant progress might be being made in specific areas or against certain pathogens. For example, targeted interventions against Listeria monocytogenes in certain food categories have shown success. The overall numbers can sometimes mask these localized improvements.
In essence, the similar numbers for some pathogens don't necessarily mean that food safety efforts are failing. Instead, they highlight the ongoing battle against persistent and easily transmissible pathogens, the impact of improved detection methods, and the inherent challenges in accurately capturing all cases of foodborne illness.
More importantly, the real problem is not these numbers, its the systemic gaps. Because looking deeper, the persistence of high foodborne illness rates exposes in how food safety systems are implemented, monitored, and updated. It underscores the need for continued vigilance, targeted interventions, and a recognition that progress is often incremental in the complex world of food safety.
What This Means for Your Food Industry’s Food Safety Management System (FSMS)
The persistence of foodborne illness rates—even in the face of technological advancements, updated regulations, and increased awareness—sends a clear message to food businesses: your Food Safety Management System (FSMS) must not be static. In 2025, the challenge isn’t merely compliance—it’s ensuring that your FSMS evolves in step with the changing realities of foodborne pathogens, surveillance technologies, and systemic vulnerabilities.
Here’s how your FSMS should respond in light of the latest data:.
1. Shift from Reactive to Proactive Risk Management
The data reinforces the need to go beyond reactive controls. A modern FSMS should be rooted in preventive strategies—such as Hazard Analysis and Critical Control Points (HACCP) and risk-based thinking—focusing on identifying and eliminating root causes before contamination or illness occurs. This requires continuous risk assessment based on current surveillance data, not outdated assumptions.
2. Embrace Data-Driven Decision Making
With CIDTs improving detection, food businesses have access to more timely and granular data than ever before. Your FSMS should incorporate tools for real-time data analysis—from supplier performance to in-plant monitoring—allowing faster interventions when deviations occur. Integrating software that supports analytics, traceability, and corrective action tracking can help close the loop between detection and response.
3. Address Human Factors More Effectively
The study highlights norovirus transmission during food handling as a major contributor. This draws attention to one of the most underestimated risks in food safety: human behavior. Your FSMS should place equal weight on employee hygiene training, behavior-based observations, and frequent internal audits of hygiene practices—especially in high-contact zones like kitchens and processing lines.
4. Reevaluate Supplier and Ingredient Controls
With globalized supply chains playing a larger role in the dynamic nature of food systems, your FSMS must reinforce rigorous supplier approval, verification, and traceability processes. This includes keeping an updated list of approved suppliers, routinely auditing them, and ensuring all incoming ingredients meet safety specifications aligned with the latest known risks.
5. Be Prepared for Emerging Threats
Although the top pathogens remain consistent, the environment in which they spread is anything but. Climate change, new food sources, consumer habits like ready-to-eat convenience foods, and shifting distribution models (e.g., ghost kitchens or delivery services) demand that your FSMS remains flexible and continuously updated. Conducting horizon scanning and integrating predictive modeling tools can help your team anticipate and mitigate future risks.
6. Strengthen Internal Audit and CAPA Systems
If the report teaches us anything, it’s that surface-level compliance isn’t enough. An effective FSMS must include strong internal audit programs that don’t just identify gaps—but drive corrective and preventive actions (CAPA) that are timely, well-documented, and data-informed. The feedback loop must be seamless from audit to action.
7. Demonstrate a Culture of Food Safety
Finally, food safety is not only about systems and processes—it’s about people. Embedding a culture of food safety into your organization, where every employee sees themselves as a custodian of public health, is essential. From leadership down to frontline staff, shared accountability and engagement are the true drivers of change.
