The d3aths of four members of a family in Mumbai, India have been linked to zinc phosphide, a toxic rat poison.
Forensic experts confirmed on Thursday, May 7, 2026 that traces of zinc phosphide were found in the watermelon consumed by the family shortly before they fell critically ill.
The Forensic Science Laboratory (FSL) report also confirmed the presence of zinc phosphide in the viscera (liver, kidney, spleen), stomach contents, bile, and abdominal fat samples of the family members, said Deputy Commissioner of Police Pravin Mundhe.
“The watermelon sample also tested positive for zinc phosphide, while all other food items were negative. The report will be studied in depth. Further probe in the case is underway” he added.
The poison was detected only after 54 rounds of forensic testing, far more than the usual 10 to 20 rounds required in poisoning cases.
According to forensic officials, the prolonged testing was needed because the victims had vomited out much of the toxin before reaching hospital, leaving behind only trace quantities.
The victims — Abdullah Dokadia (44), his wife Nasreen (35), and daughters Ayesha (16) and Zainab (12) — had eaten watermelon around 1.30 am on April 26, 2026 after hosting relatives for dinner at their home in Mughal Building in Bhendi Bazaar’s Pydhonie area.
Only the four family members consumed the watermelon.
Hours later, all of them began vomiting and suffering from severe discomfort and diarrhoea.
They were rushed to hospitals, but d!ed one after another through the day.
Twelve-year-old Zainab was the first to die around 10 am, while Abdullah succumbed around 10 pm.
Doctors at JJ Hospital reportedly carried out stomach wash procedures and administered intensive treatment, but failed to save the family.
Forensic experts say zinc phosphide releases a lethal gas inside the human body and can k!ll within hour.
Police are still investigating whether the deaths were accidental, suicidal or homicidal.
Officials said no rat poison was found inside the Dokadia residence.
Forensic report ruled out contamination in the chicken pulao and other food items consumed during the family gathering earlier that evening.
Investigators are also examining ayurvedic and unani medicines recovered from the house.
Police dismissed speculation about financial distress in the family and said there was no immediate indication of internal conflict.
