A new food poisoning wave has struck Antananarivo. Sixty-seven residents of Andranoro in Antehiroka commune, Ambohidratrimo district, were admitted to hospital emergency departments yesterday. The Joseph Ravoahangy Andrianavalona (JRA) University Hospital received 34 patients while Anosiala University Hospital admitted 33 others, according to sources from the Ministry of Public Health. Two victims are in critical condition, and two pregnant women are among the sick.

Initial investigations suggest contaminated bulk palm oil may be responsible. Several victims had consumed "composé" (a local dish) from a street vendor who typically supplies them. Unable to find her usual cooking oil, the vendor switched to another product. Suspicions center on this new oil, though the outbreak also affected people who didn't consume food from this vendor. The vendor herself and one of her children are among the hospitalized patients.

Antehiroka rural commune states the cause remains uncertain and both cooking oil and eggs are being investigated. Residents experiencing headaches, dizziness, stomach pain, or unusual symptoms—especially after consuming or using oil—are urged to seek immediate medical attention.

Patients arrived gradually at hospitals. By late afternoon yesterday, 61 had been admitted; by evening, the number reached 67. Some were initially taken to Joseph Raseta Befelatànana University Hospital before being transferred to JRA. Several patients' conditions are already improving.

The Ministry of Commerce and Consumption ordered temporary closure of the shop that sold the suspect oil. Samples were taken from the oil and food remnants including ground meat and snout salad seized from the vendor's stall, as well as from a fritter seller mentioned by victims. Preparation areas were inspected. Initial findings show the oil had not exceeded its expiration date. Administrative and medical investigations continue. Laboratory results will determine the exact cause of the outbreak.

The state is covering all medical treatment and associated costs for victims.
