Doctors believe the rapid symptoms point to food poisoning from bacteria or toxins, not because watermelon itself is dangerous.
As Dr. RR Dutta explained, "Consumption followed by the onset of symptoms within 3-5 hours does not point toward watermelon as a 'toxic' food, but rather toward an acute toxin-mediated gastroenteritis or exposure to a highly contaminated source," he explained.
Experts recommend always refrigerating cut fruit and keeping kitchen hygiene tight to stay safe.
Investigations are ongoing, but no foul play is suspected.
