Abstract
This study examined the nature and level of foodborne pathogens and spoilage bacteria in Carite (Scomberomorus brasiliensis) available to consumers in various market types in Trinidad, West Indies. Chilled and frozen samples (52) were collected between the months of January and June 2014. Popular purchasing venues include from supermarkets (30), wholesale markets, retail outlets, roadside fish vendors and landing sites. Total aerobes were enumerated using standard plate count methods. Samples were also plated on selective media: MacConkey, Eosin Methylene Blue, Aeromonas (Ryan Medium) and Baird Parker. Colonies were selected, purified and biochemically pre-screened before final identification using API20E. Carite purchased from supermarkets, wholesale markets, retail outlets, fish vendors and landing sites had mean aerobic counts of (Log CFU g-1) 5.31 ± 2.11, 4.43 ± 0.49, 4.53 ± 0.54, 3.06 ± 0.05 and 2.96 ± 0.40 respectively. Bacterial types with the highest overall prevalence rates include Staphylococcus aureus (15.4 %),Escherichia coli (7.7 %),Proteus mirabilis (9.6 %),and Rauttella planticola (7.7 %).
