At least 75 persons suffered food poisoning after eating galunggong and green mussels in Barangay Inirangan in Bayambang town, Pangasinan, according to a report on "Saksi."
According to the municipal health office, the items were bought from an ambulant vendor that passed through the barangay.
Officials are conducting an investigation to determine whether the cause of food poisoning is red tide toxin.
