Abstract

Introduction: Beaches are one of the important coastal resources in Malaysia and become the attractions to the local and foreign tourist. Presence of infectious microorganisms in recreational water can cause human health problems such as gastrointestinal illness, health symptoms of nose, eyes, and skin. Staphylococcus aureus and Salmonella were chosen as the most suitable indicators for recreational marine waters. Objectives: This study was designed to determine concentrations of Staphylococcrrs urrrerrs and Salmonella at Morib beach and general perceived human health symptoms from beach water exposure. It was also designed to determine the relationship between physicochemical characteristics and Sraphylococcus uurercs and Salmonella concentrations. Methodology: A cross sectional study has been conducted at Morib beach, Selangor. A set of adapted questionnaire was distributed to the visitors who exposed to beach water in Morib beach. The beach water sample was collected at eight locations in Morib beach. The water samples were filtered using membrane filtration technique. The membrane containing bacterial cells were placed on a selective medium: Staphylococcus 110 medium far Staphylococczrs nr1rezr.a and xylose lysine desoxycholate agar (XLD agar) for Salmonelia. The colonies appeared were count and analysed. Physicochemical parameters such as temperature, pH, dissolved oxygen (DO), electrical conductivity (EC), salinity, oxidation reduction potential (ORP), and turbidity were measured on site by using YSI Profesional Plus hand-held multi probe. Results and Discussion: Both concentrations of Salmonella (87.00±40.95cfu100ml) and Staphylococcus atrrerrs (100.67±82.40 cfu/100ml) highest recorded at sampling point K16 and K17 which the possible area near to the sources of pig waste effluent runoff The highest percentage of perceived health symptoms were none detected (56.4%). This study suggested that perceived human health symptoms among beach bathers may associated with other factors. There were significant relationship between concentrations of Salmonella and temperature (I=0.96, p< 0.01), DO (r = 0.94, p<0.01) and salinity (r = -0.74, p< 0.05). For the concentrations of Staphylococcus aureus, there wcre significant relationship between concentrations of Staphylococctrs arrreus with temperature (r = 0.99, p< 0.01), DO (r = 0.96, p< 0.01), salinity (r = -0.80, p< 0.05) and EC (r = -0.78, p< 0.05). Conclusion: From the finding, this study has determined the highest concentrations of Salmonella and S~aphylococcusaureus were found near the pig waste effluent runoffs which were at sampling point K16 and K17. However, none of perceived health sqmptums from bcach water exposure was observed. Keywords: Staphylococcus aurreus . Salmonella . Gastrointestinal illness . Beach water exposure
