The most dangerous thing at a pumpkin patch may not be the pumpkin. And the greatest health risk at an apple orchard may have nothing to do with the apples.
It could be the pony your child rides. The goat they pet. The hamburger cooked on a makeshift grill. Or the shared barrel of water where children take turns bobbing for apples.
These are the experiences that make fall traditions memorable. But they can also introduce risks involving animal-borne pathogens, contaminated surfaces, unsafe food handling, and inadequate sanitation.
For most families, a day at the farm ends with photographs and happy memories. For others, exposure to an invisible pathogen can mean an emergency room, kidney failure, or worse.
Young children, older adults, pregnant women, and people with weakened immune systems can face particularly serious consequences.
The problem is not that pumpkin patches and apple orchards are inherently unsafe. It is that we have spent decades celebrating these family traditions without consistently recognizing the public health responsibilities that come with them.
And as a developing E. coli investigation in California reminds us, those responsibilities are far from theoretical.
A pumpkin patch is rarely just a pumpkin patch
In San Luis Obispo County, CA, public health officials are investigating five cases of Shiga toxin-producing E. coli and a possible connection to Brookshire Farms, a seasonal agricultural attraction. Several children have reportedly experienced severe illness.
The farm voluntarily closed and has cooperated with investigators. The source of the infections has not been established.
That distinction is essential. A suspected association does not establish causation, and investigators must be allowed to follow the evidence.
But the investigation raises questions that extend far beyond one farm.
When families visit agricultural attractions, they are often entering environments where livestock, recreational activities, food preparation, shared equipment, and large crowds intersect.
A working farm may be accustomed to managing the hazards of agricultural production. Hosting hundreds or thousands of visitors, particularly young children, creates an entirely different set of responsibilities.
The public may see a wholesome family destination.
A public health professional sees multiple opportunities for pathogens to move between animals, the environment, food, and people.
Both perspectives can be true.
The pony ride, the petting zoo, and the invisible passenger
Consider a child who rides a pony, pets a goat, or feeds a calf.
Cattle, sheep, and goats can carry Shiga toxin-producing E. coli without appearing sick. Other animals may carry Salmonella, Campylobacter, or Cryptosporidium, a parasite capable of causing severe gastrointestinal illness.
Transmission does not always require direct contact with an infected animal. Pathogens can be present in manure, soil, bedding, fencing, gates and on other surfaces. They can travel on shoes, clothing, stroller wheels and hands.
A child may touch a fence, climb into a stroller, and eat a cookie minutes later. That simple sequence can create an exposure pathway.
Young children are particularly vulnerable because their natural behaviors include touching their faces, putting fingers in their mouths, and playing close to the ground.
These are not failures of parenting. They are predictable behaviors that should be anticipated when designing attractions for children.
The responsibility cannot rest entirely on a parent remembering to bring hand sanitizer.
Operators must provide appropriate separation between animal areas and eating spaces, accessible handwashing facilities with soap and running water, trained staff, and clear instructions for visitors.
Hand sanitizer can be useful in some circumstances, but it is not an adequate substitute for handwashing in every animal-contact setting.
What about that hamburger from the temporary grill?
Now consider another familiar fall attraction: the food stand at the same location.
Perhaps it is a temporary grill serving hamburgers and hot dogs. Maybe it is a concession trailer preparing sandwiches, caramel apples, or freshly pressed cider.
These operations may be temporary, but the microorganisms do not care.
Ground beef still requires cooking to a safe internal temperature of 160 degrees F. Poultry requires 165 degrees F. Cold foods requiring refrigeration must be maintained at 40 degrees F or below, while hot foods should be held at 135 degrees F or above under the FDA Food Code.
Employees still need appropriate handwashing facilities, safe water, clean utensils, and procedures to prevent cross-contamination. And food handlers must be able to manage these responsibilities while serving long lines of hungry families.
A makeshift operation does not necessarily mean an unsafe operation. Many temporary food vendors maintain excellent food safety practices. But temporary facilities can introduce challenges involving refrigeration, temperature control, potable water, sanitation, waste disposal and employee hygiene.
The risks become particularly concerning when food preparation occurs near animal environments or when visitors move directly from petting zoos and livestock areas into eating spaces. A hamburger does not become safer because it is served beside a pumpkin patch.
Even bobbing for apples deserves another look
Some fall traditions introduce risks that have little to do with cooking.
Take bobbing for apples.
The traditional activity involves multiple participants placing their faces and mouths into a shared container of water while attempting to retrieve floating apples.
From an infectious disease perspective, the concern is obvious. Shared water can become contaminated with saliva, nasal secretions, and microorganisms transferred from participants’ faces and hands. The activity creates opportunities for person-to-person transmission, particularly when the water is not replaced between participants.
This does not mean every apple-bobbing event causes illness. It means the traditional format creates avoidable opportunities for exposure.
There are safer alternatives that preserve the fun, including individual containers, individually handled apples, or games that eliminate shared mouth contact with water.
The point is not to eliminate childhood traditions. It is to recognize when a tradition can be redesigned to reduce foreseeable risks.
History has already warned us
These concerns are not hypothetical.
In 2004, an E. coli O157:H7 outbreak associated with a petting zoo at the North Carolina State Fair resulted in more than 100 illnesses, including children who developed hemolytic uremic syndrome (HUS), a serious complication that can result in kidney failure, brain damage or death.
Investigators documented risks associated with contaminated animal environments and the movement of pathogens beyond animal enclosures.
Other outbreaks have been linked to livestock exhibitions, pumpkin patch field trips, and agricultural attractions where visitors became ill without necessarily touching animals.
Apple orchards have also figured prominently in food safety history, particularly through outbreaks associated with unpasteurized cider.
The 1996 Odwalla outbreak, which killed a child, demonstrated the consequences of inadequate controls in juice production and helped accelerate changes in federal juice safety requirements.
In 2025, the Centers for Disease Control and Prevention published an analysis of animal-contact outbreaks reported between 2009 and 2021.
During that period, 557 outbreaks resulted in 14,377 illnesses, 2,656 hospitalizations, and 22 deaths.
These figures concern animal-contact outbreaks across multiple settings, not every illness associated with agritourism. They do not include all possible risks associated with temporary food service or shared recreational activities.
But they demonstrate that the underlying public health problem is longstanding and well documented.
We have known for decades that agricultural environments can expose visitors to infectious disease hazards. The question is whether we have done enough with that knowledge.
Not everyone faces the same consequences
A healthy adult exposed to a gastrointestinal pathogen may experience several miserable days of illness and recover.
For someone else, the same exposure can have devastating consequences.
Young children face increased risks from certain infections, including STEC-associated HUS.
Older adults may be more susceptible to serious complications and dehydration.
Pregnant women face particular concerns from pathogens such as Listeria monocytogenes, which can cause pregnancy loss, stillbirth, or severe newborn illness.
People with weakened immune systems may experience more severe infections or prolonged illness.
These differences matter when agricultural attractions promote themselves as family-friendly destinations. A destination designed for families must account for the vulnerabilities of the people it invites. That means prevention cannot be based solely on what a healthy adult might tolerate.
It must consider the child reaching through the fence, the grandmother enjoying a hayride, the pregnant mother purchasing lunch, and the visitor whose immune system cannot respond effectively to an infection.
The standard of protection should reflect the people most likely to be harmed, not merely those most likely to recover.
When entertainment expands, responsibility must expand with it
Agritourism has become an important source of revenue for many agricultural businesses. Pumpkin patches have evolved into seasonal entertainment destinations. Apple orchards may offer restaurants, bakeries, animal encounters, rides, games and festivals.
There is nothing inherently wrong with that evolution. But each additional attraction introduces responsibilities that may extend beyond traditional agricultural practices.
A pony ride requires attention to animal health, hygiene, and visitor contact.
A petting zoo requires controls for animal-associated pathogens and environmental contamination.
A temporary food stand requires appropriate food safety practices and equipment.
An apple-bobbing station requires consideration of shared-water hygiene.
A cider operation requires controls appropriate to the product and processing method.
And the entire property requires attention to how visitors move between these activities.
A family might pet goats, ride a pony, purchase hamburgers, and share a picnic table within the same hour. That movement is precisely why public health protection must be considered across the entire visitor experience.
Individual attractions cannot be treated as isolated activities when the same visitors, employees, equipment,and environments connect them.
Prevention should begin before opening day
Public health guidance for animal exhibits and temporary food service already exists.
The CDC and public health veterinary organizations have long emphasized handwashing, separation of animal and eating areas, visitor education, and environmental controls. Food safety regulations establish expectations for cooking, holding temperatures, sanitation, and employee hygiene.
The problem is not necessarily an absence of scientific knowledge. It is whether those expectations are consistently understood, implemented, and verified across seasonal operations.
I believe agricultural attractions should conduct comprehensive public health risk assessments before welcoming visitors each season.
Those assessments should consider the entire property, including animal exhibits, pony rides, food vendors, cider operations, shared recreational activities, sanitation facilities and visitor traffic patterns.
Seasonal employees should receive practical training appropriate to their responsibilities.
Operators should be prepared to respond quickly when illness is reported, cooperate with public health authorities, and communicate transparently with visitors.
Local regulators should also consider whether oversight systems adequately address businesses that combine agriculture, entertainment, animal contact, and food service.
This is not about burdening farmers with unnecessary requirements.
It is about recognizing that a business inviting families onto its property has responsibilities that extend beyond agricultural production.
The cost of doing nothing
I know what it means for an ordinary day to become the beginning of an unimaginable tragedy. For more than three decades, that experience has shaped my work in food safety, public health, and consumer protection.
I also know that families rarely enter these situations believing something terrible is about to happen. Parents take their children to restaurants, grocery stores, school events, and farms because these are normal parts of life. They trust that the businesses and institutions welcoming them have taken reasonable steps to protect their health.
That trust carries responsibility.
When a child becomes seriously ill following a family outing, the consequences extend far beyond the immediate medical emergency. There may be hospitalization, kidney complications, long-term health consequences, financial hardship, and emotional trauma.
In the worst cases, there is a chair at the family table that will remain empty forever.
We should not need another tragedy to recognize the importance of prevention.
Keep the traditions. Change the expectations.
I want families to visit pumpkin patches and apple orchards.
I want children to meet farm animals, learn about agriculture, explore the outdoors, and experience traditions that connect generations.
But I also want operators, regulators, and public health leaders to recognize that the hazards associated with these experiences extend far beyond the food being grown or sold.
Sometimes the risk is the hamburger cooked on a temporary grill.
Sometimes it is the goat that appears perfectly healthy.
Sometimes it is the contaminated fence a child touches before eating.
Sometimes it is the shared water in an apple-bobbing barrel.
And sometimes investigators must work for weeks to determine exactly how an exposure occurred.
The lesson is not that every farm attraction is dangerous. It is that familiar, wholesome surroundings do not make infectious disease hazards disappear.
We should preserve the traditions while strengthening the protections that make them possible.
Because the moment a farm invites families through its gates, it becomes more than an agricultural operation. It becomes a place with public health responsibilities.
And the success of a fall festival should never be measured solely by the number of pumpkins sold, pony rides completed, or photographs taken.
It should also be measured by whether families return home healthy.
The most important thing a child should bring home from a pumpkin patch is a memory, not an infection.
