A fresh apple straight from the market or a mango picked off the tree often feels harmless, even wholesome. But during outbreak season, that same fruit can quietly become a carrier of viruses, bacteria,
and chemicals invisible to the eye. What looks clean isn’t always safe. Health experts say skipping a proper wash could expose you to infections far more serious than a simple stomach upset.
“Originating in fruit bats, the Nipah virus can spread to animals and humans through contaminated food and close contact. Once infected, patients can develop severe and often fatal illness, making prevention and early awareness absolutely critical,” says Dr. Vikram Vora, Medical Director, International SOS (Indian Subcontinent).
How Fruit Becomes A Silent Carrier
Fruit bats, the natural reservoir for Nipah, often feed on orchard produce at night. In the process, they leave behind saliva, urine, or partially eaten fruit. The contamination may not be visible, yet it can remain infectious.
Dr. Tanu Singhal, Consultant, Pediatrics and Infectious Disease, Kokilaben Dhirubhai Ambani Hospital, explains, “These bats can shed the virus through saliva, urine, or droppings while feeding on fruits. The virus can survive for three to seven days on the fruit surface.”
What makes this particularly dangerous is how normal the fruit looks. “Contamination is not always obvious. Consuming such fruits without thorough washing or peeling can provide a direct route for the virus to enter the body,” she adds.
Understanding The Nipah Risk
Nipah virus isn’t just another seasonal illness. It has a high fatality rate and progresses rapidly. According to Dr. Vora, transmission can occur through contaminated food, infected animals, or even close contact with infected individuals.
Symptoms may begin mildly with fever, headache, vomiting, and muscle pain, but can escalate quickly to brain inflammation, confusion, seizures, and coma. “There is no specific antiviral or vaccine. Medical care focuses on managing symptoms, which makes prevention absolutely essential,” he notes.
In regions reporting outbreaks, travellers and residents alike must be vigilant about food hygiene and environmental exposure.
It’s Not Just One Virus
While Nipah headlines the risk, it’s only part of the problem. “Consuming unwashed fruits and vegetables can expose you to bacteria like Salmonella, E. coli, Listeria, and Campylobacter,” says Dr. Manisha Arora, Director – Internal Medicine at CK Birla Hospital, Delhi. Viral infections like norovirus and other food poisoning pathogens are also common.
Symptoms can range from diarrhoea and vomiting to persistent fever and severe dehydration. Vulnerable groups – children, pregnant women, and the elderly – face higher risks.
There’s also a chemical angle. “Pesticides can accumulate over time and are linked to long-term health problems such as hormonal disruption, neurological issues, and even cancer,” she cautions.
Simple Steps That Protect Your Family
Fortunately, prevention is straightforward. All three doctors agree on practical measures: wash fruits thoroughly under running water, peel where possible, discard fallen or partially eaten produce, and avoid raw date palm juice unless boiled. Dr. Arora recommends soaking fruits in a mild salt or vinegar solution and using a brush for thick skins. Hand hygiene and proper storage further reduce contamination.
“These basic food safety measures are a critical part of personal protection,” says Dr. Singhal.
In outbreak season, safety isn’t about fear, but it’s about habit. A few extra seconds spent washing and peeling fruit can significantly reduce exposure to life-threatening infections. When treatment options are limited, hygiene becomes the most powerful medicine.
