World Food Safety Day is on June 7, 2026.
Even after 30 years of doing this, every few years a number comes up that stops me. This week the numbers are 866 million.
This is how many people the World Health Organization (WHO) estimates get sick every year from unsafe food. and Of these, 1.5 million died.. New WHO estimates released this week Lancet Global Health Just in time for World Food Safety Day on June 7, here’s the most complete explanation yet of the toll we’ve had on foodborne illnesses around the world. The report covers 42 risks, including bacteria, viruses, parasites and, for the first time at this scale, chemical pollutants such as arsenic, lead and methylmercury, across 194 countries from 2000 to 2021.
I have devoted my entire career to representing the people behind statistics like these. An infant with hemolytic uremic syndrome is receiving dialysis after eating a hamburger. An elderly woman who never returned home from the hospital after eating a melon infected with Listeria bacteria. The families I sat with in living rooms across this country had no idea that a meal could rob them of everything. So when the WHO puts the number 866 million on the table, the spreadsheet doesn’t show up. You see 866 million living rooms.
The part that should make us all angry
Here’s what I can’t pass up: Children under five make up only about 9% of the world’s population, but they account for nearly a third of all foodborne illnesses. — and they account for a cruel share of deaths, mostly from diarrheal diseases. The smallest and most vulnerable people on the planet are paying the highest price for problems we know how to prevent.
And it’s very unequal. WHO found that Africa and Southeast Asia together account for about three-quarters of the world’s food poisoning cases and about 60% of deaths. A child’s risk of dying from contaminated food has nothing to do with what the child did and almost everything to do with where that child was born. That is, whether there is clean water, a reliable refrigerator, basic sanitation, and whether a doctor is nearby.
There is one bright spot worth saying out loud. The overall burden has actually decreased since 2000. That’s important. That tells us that this is not hopeless. This refers to investment, surveillance, and basic public health tasks. We’re not defying the laws of physics here. We’re fighting neglect, underfunding, and the silos that continue to build between the people who can solve these problems.
It’s no longer just a bug.
For most of my career, my world was a pathogen. E. coli O157:H7; salmonella, Listeriahepatitis A, Cyclospore. They still cause the overwhelming majority of diseases, and they will always be my battle.
But the new estimates point out something too many of us have ignored. Chemical contaminants cause only a small proportion of foodborne illnesses. diseaseThey were responsible for most of the foodborne dead In 2021, most were traced to inorganic arsenic and lead. Once these metals enter the food chain, they often cannot be taken out again. That’s heart disease, cancer, and irreversible damage to children’s developing brains on the dinner table. This means that food safety can no longer be neatly divided between ‘pathogens’ and ‘environments’. It’s all one problem.
What “Working Together” Really Means
WHO calls the answer a “One Health” approach that links human health, animal health, plant health and the environment and breaks down the walls between the health, agriculture and environment sectors. I will state it more clearly: No one has this problem to themselves, which is why it will never be fully resolved.
Growers blame processors. Processors blame distributors. Regulators are underfunded and stretched thin. Lawsuits (in my world) come last, after the damage has already been done. I’ve spent my career on the last line of accountability, and I’m going to tell you the truth I’ve been telling audiences for years. I would happily go out of business. Every incident I submit is one that could have been prevented by someone, somewhere.
Working together means several specific things.
• Prevent at the source. Better agricultural practices, stricter industrial controls, and actual environmental regulations ensure that biological or chemical contamination does not reach our food in the first place.
• Fund the basics. Access to clean water, sanitation, pasteurization, refrigeration and treatment. This is not some exotic technology. That’s the difference between a sick child who recovers and a child who doesn’t.
• Invest in surveillance. You can’t fix what you can’t see. The reason we have these numbers now is because scientists did the boring work of calculating them. Climate change is increasing the risk of contamination, and antimicrobial resistance is making infections more difficult to treat. This needs more attention.
• Don’t treat food safety as someone else’s department. Industry, government, public health, and yes, trials are all part of it.
This affects every meal.
The WHO Director-General said this week something he wished I had said first. Food safety is not an abstract issue; it affects every meal, every family, every day. The paper’s lead author put it even more bluntly: “Delays cost lives.”
I have spent more than 30 years watching the cost of delays one family at a time. The new estimates are simply a global figure for what I have seen in living rooms, hospital rooms, and, too often, cemeteries.
866 million diseases. 1.5 million people died. It’s a burden comparable to tuberculosis, HIV and malaria. And the most important thing to understand about all of this is that it is preventable. Not someday, not in theory. Just use the knowledge and tools we already have.
So, as World Food Safety Day approaches, my question is simple: Whether you grow food, process it, sell it, regulate it, research it, or feed your family, this is your problem too. Let’s stop pointing across silos at each other and start working as if the lives of 866 million people depend on it.
Because they are.
