A amêijoa-macha (Venerupis pullastra) é um dos bivalves mais consumidos em Portugal. No presente estudo foi avaliada a qualidade microbiológica desta amêijoa capturada na Trafaria através do controle do pH e da contagem de microorganismos indicadores de poluição fecal, tais como Enterobacteriaceae e indicadores de degradação como as bactérias ácido-lácticas, microrganismos viáveis totais e bactérias produtoras de H2S. A amêijoa foi armazenada a diferentes temperaturas (4ºC, 9ºC), e avaliou-se a sua qualidade microbiológica e química (através das técnicas acima referidas) ao longo do tempo nestas temperaturas. Determinou-se que seria benéfico a utilização da temperatura 4 ºC para períodos de armazenamento superiores a 2 dias.
Clams (Venerupis pullastra) are one of the most consumed bivalves in Portugal. In the present investigation the chemical and microbiological quality, of the clam captured in Trafaria, was evaluated by control of pH and of the count of fecal pollution indicators, such as Enterobacteriaceae and spoilage indicators like acid lactic bacteria, total count of viable microorganisms and H2S producing bacteria . Clams were stored at different temperatures (4ºC and 9ºC), and its chemical and microbiological quality was evaluated (through the techniques above) over time given the varying temperatures. It was determined that it would be beneficial to use the temperature of 4°C for storage periods longer than 2 days.
