Mati Bay in Davao Oriental is among coastal areas in seven provinces that are positive for red tide, the Bureau of Fisheries and Aquatic Resources (BFAR) said on Friday.
The other affected areas are the coastal waters of Dauis and Tagbilaran City in Bohol; Tambobo Bay, Siaton in Negros Oriental; Daram Island, and Zumarraga, Cambututay, Irong-irong, San Pedro, Maqueda and Villareal Bays in Western Samar; Calubian, Carigara and Ormoc Bays, and Cancabato Bay, Tacloban City, Leyte; Balite Bay, Murcielagos Bay in Zamboanga del Norte; and Lianga and Bislig Bays in Surigao del Sur.
BFAR said latest results inthecoastal areas indicated paralytic shellfish poison (PSP), or the toxin that causes red tide, is beyond the regulatory limit.
BFAR warned that all types of shellfish and “alamang” (tiny shrimp) gathered from said areas are unsafe for human consumption.
Fish, squids, regular shrimps, and crabs are safe to eat provided that they are fresh and washed thoroughly.
Internal organs such as gills and intestines must also be removed before cooking.
Eating shellfish products with red tide can cause death. Early symptoms of paralytic shellfish poisoning include tingling of the lips and tongue, which may begin within minutes of eating poisonous shellfish or may take an hour or two to develop. (PNA)
