Investigators in Mumbai continue grappling with a baffling case after zinc phosphide—a toxic rodenticide—claimed the lives of four family members who ate fruit together in the early morning hours of April 26, 2026, yet the source of contamination remains unknown more than three months later.
Laboratory technicians discovered the deadly compound in tissue samples from 44-year-old Abdullah Dokadia, his 35-year-old wife Nasreen, and their daughters Ayesha, 16, and Zainab, 13. The same poison turned up in watermelon fragments collected from the Pydhonie apartment where the family lived. Testing finished in early June showed no presence of the toxin in knives, plates, rice, chicken pulao, or herbal rodent repellent seized from the residence, leaving authorities without answers about how the poison entered the food.
Police continue examining four scenarios: deliberate murder, murder-suicide, mass suicide, and unintentional contamination. Detectives await final autopsy reports for Zainab and results from digital forensic examination of cell phones owned by the victims. They are also looking into whether money troubles played any role. The incident—instantly labeled the “watermelon deaths” across Indian media—triggered widespread alarm in produce markets, with melon prices crashing by Rs 5 to Rs 7 per kilo in Navi Mumbai as sellers faced devastating economic damage from the publicity.
Timeline of the Tragedy
The Dokadias welcomed relatives for a biryani dinner on the evening of April 25. Guests departed near 10:30 p.m., after which the four family members ate watermelon between 1 and 1:30 a.m.—their final meal.
Severe symptoms appeared rapidly, with everyone suffering from vomiting and diarrhea. Dr. Zaid Qureshi, a neighbor living on the fourth floor, came in response to the crisis and found the youngest child struggling to breathe.
“I noticed that the youngest of the four individuals was experiencing difficulty breathing. I administered CPR. However, as her condition did not improve, she was taken to a nearby hospital. She passed away,” Qureshi told BBC Marathi.
Paramedics rushed the remaining three to JJ Hospital in Mumbai for emergency care. The youngest daughter died at 10:15 a.m. on April 26. Nasreen and Ayesha died shortly thereafter, while Abdullah died at 10:30 p.m. that same day. Stomach pumping and intensive treatment could not save anyone.
Deadly Chemical Discovered in Organs and Fruit
The cause of death went unexplained for 11 days. Mumbai’s Forensic Science Laboratory (FSL) conducted 54 tests on items removed from the residence, including leftover watermelon pieces, kitchen utensils, plates, and additional food items. The State Food and Drug Administration examined samples for contamination. On May 7, the FSL released findings to Mumbai Police revealing that zinc phosphide was present in livers, kidneys, spleens, stomach contents, bile, and fat tissue from all four deceased individuals—and crucially, in the watermelon too. All other food tested showed no traces.
Deputy Commissioner of Police Pravin Mundhe stated that an accidental death case had been registered, with the JJ Marg police station gathering testimony from relatives and neighbors. Autopsies concluded that zinc phosphide poisoning caused the family’s deaths.
Rapid Onset of Fatal Symptoms
This inorganic substance combines phosphorus with zinc and is sold throughout India to kill rodents, making it widely available for purchase. When swallowed, stomach acid converts it into phosphine gas—a lethal vapor that enters the blood, penetrates cell membranes, and halts cellular energy production. Warning signs emerge 30 to 60 minutes following ingestion, featuring nausea, dizziness, breathing trouble, and convulsions. Advanced poisoning triggers liver damage, kidney damage, cognitive impairment, and loss of consciousness. Forensic experts quoted in media reports indicate successful treatment requires action within approximately 60 minutes of exposure, beyond which even intensive medical care seldom works. Internal medicine physician Dr. Hemalata Arora observed that gastric lavage is effective only during that brief timeframe. Former FSL director Dr. Rukmani Krishnamurthy remarked that the substance typically comes as powder, suggesting it may have been scattered onto sliced fruit. Forensic specialists Dr. Bhushan Rokade and Dr. Sanjay Surase have provided expert analysis, with toxicology professionals theorizing that Zainab perished first due to her lower body weight resulting in diminished resistance to the chemical.
Investigation Expands as Questions Mount
Authorities report the residential building suffered from ongoing rodent infestations, yet no evidence surfaced showing rat poison was stored in the Dokadia household. This finding has prompted police to consider all angles—whether the contamination happened accidentally or someone deliberately poisoned the family. Officers detained two fruit vendors discovered using rodenticide on their products, though no official connection to the Dokadia case has been made.
On May 19, Mumbai Police submitted additional salt samples from the home to the FSL for more analysis. Detectives now believe the toxin could have been blended with table salt and dusted onto the sliced fruit prior to eating, which would mean the family may have detected only a strange salty flavor before becoming sick. Over 100 people have provided statements to police regarding the fatalities, which remain categorized as accidental.
More than three months past the April 26 tragedy, officials still confront one of contemporary India’s most perplexing fatal poisoning cases—a catastrophe that started with fruit eaten after midnight and concluded with four deaths, fear spreading through Mumbai’s fruit markets, and mysteries for forensic scientists. The investigation persists, with no further test results made public following the June analysis period.
