Microbiological quality of whole and filleted shelf-tilapia

Despite fish being a rich source of animal nutrients and having numerous associated health benefits, it is an extremely perishable food, prone to a wide range of hazards. The bacterial load associated with shelf-whole-fish organs (e.g. digestive tracts and skin) or mishandling of fish may be a vehicle of infection and become a risk to public health. The objective of this paper is to evaluate the microbiological quality of whole ungutted and filleted shelf-tilapia, as well as assess the safety for human consumption. For this purpose, in order to investigate the distribution and occurrence of bacterial populations, the count of total and thermotolerant coliforms, coagulase-positive Staphylococcus and presence of Salmonella spp. was determined. This paper shows that all fish organs were contaminated with thermotolerant coliform. Skin and fillet show higher populations and occurrence of all microorganisms analyzed. Lower bacterial populations were recovered from the gut and muscles of whole tilapia. Two samples of fillet were contaminated with coagulase-positive Staphylococcus. It can be concluded that the skin and filleted tilapia are important carriers of food-borne pathogens. In addition, fish might become an important cross and self-contamination source.

Metodologia Microbiológica Convencional e Reação em Cadeia pela Polimerase (PCR) na detecção de Salmonella spp em carcaças de frango

Salmonella is the etiological agent responsible for one of the most important Food Borne Disease (FBD), Salmonellosis, which generates significant economic consequences in several countries, including Brazil. Poultry meat is one of the most important disseminators of the pathogen. Accordingly, several countries have developed programs trying to reduce the prevalence of Salmonella in poultry meat. Such programs are based on the research of the pathogen in the carcasses, establishing a maximum limit of positive samples at each set of analysis. The Salmonella scans are usually made using the conventional microbiological methods, which tend to be expensive and time consuming. In recent years were developed rapid methods such as polymerase chain reaction (PCR), which can greatly shorten the results time, showing greater sensitivity and specificity than conventional methodology

Helmintoses zoonóticas transmitidas pelo consumo inadequado de peixes

Among the major food-borne parasitic zoonoses, the helminthiasis transmitted by consumption of fish have been highlighted because they involve a large number of individuals in many regions of the world in recent years. In the past, these parasitosis were restricted to underdeveloped nations or with peculiar eating habits; however the process of globalization of food production, the increased international travel and consumption of fish for their nutritional benefits caused the expansion into new areas, which had never before been recorded, making it a serious public health problem in some countries. This review discuss the main helminths transmitted by eating raw or undercooked fish, in order to alert the public, the scientific community and health authorities about their risks to human health, as well as stimulate the realization of new researches that contributes to a greater knowledge of the epidemiological situation in the country of these parasites and the development of strategies for prevention and control of them.
