Purpose – In order to improve the safety of seafood in the domestic seafood distribution chains (DSDCs) in Vietnam, a better understanding of current hygiene and practices compliance with government regulations is needed. The paper aims to discuss this issue. Design/methodology/approach – Infrastructure conditions and documents related to hygiene procedures of 50 trading places were evaluated using checklists. The hygiene handling practices of 135 fish distributors were also observed by using notational analysis methods. This notational analysis method focused on actions related to microbiological contamination in terms of hand washing or glove changing and the cleaning and sanitising of tools and equipment. Additionally, microbiological quality of 135 samples of raw finfish at points along distribution chains was compared with national standards. Findings – The results indicated that all trading places could be classified as non-compliant or seriously non-compliant with the regulations. The practices of fish distributors were also assessed to be at high risk for contamination of raw fish. The findings showed that approximately 42 and 39 per cent of samples from fishing ports and fish markets, respectively were classified as unacceptable according to the microbiological standards of Vietnam. Research limitations/implications – The present study is limited to research only from fish landing at fishing ports to the distribution to consumers at retail markets. Originality/value – Recommendations for improving food safety in the DSDCs in Vietnam have been developed from the findings of this study and are provided. However, due to similarities with fish distribution chains in other countries, these recommendations may have broader application.

Domiati cheese is the most popular brand of cheese ripened in brine in the Middle East in terms of consumed quantities. This study was performed to investigate the impact of the microbiological quality of the used raw materials, the applied traditional processing techniques and ripening period on the quality and safety of the produced cheese. Three hundred random composite samples were collected from three factories at Fayoum Governorate, Egypt. Collected samples represent twenty-five each of: raw milk, table salt, calf rennet, microbial rennet, water, environmental air, whey, fresh cheese, ripened cheese & swabs from: worker hands; cheese molds and utensils; tanks. All samples were examined microbiologically for Standard Plate Count (SPC), coliforms count, Staphylococcus aureus (S. aureus) count, total yeast & mould count, presence of E. coli, Salmonellae and Listeria monocytogenes (L. monocytogenes). The mean value of SPC, coliforms, S. aureus and total yeast & mould counts ranged from (79×102 CFU/m3 for air to 13×108 CFU/g for fresh cheese), (7×102 MPN/ cm2 for tank swabs to 80×106 MPN/ml for raw milk), (9×102 CFU/g for salt to 69×106 CFU/g for fresh cheese) and (2×102 CFU/cm2 for hand swabs to 60×104 CFU/g for fresh cheese), respectively. Whereas, E. coli, Salmonella and L. monocytogenes failed to be detected in all examined samples. There were significant differences in all determined microbiological parameters (p ≤0.05) between fresh and ripened cheese which may be attributed to different adverse conditions such as water activity, pH, salt content and temperature carried out to improve the quality of the product.

In Germany the application of procedures such as flocculation and filtration in the preparation of drinking water results in the annual production of an estimated 500,000 t of sediments and sludges. Some of these residues have a potential for being reused, for example in agriculture, forestry, brickworks or waste water treatment. To assess the microbiological quality of residues from waterworks methods for the detection of enterobacteria, Escherichia coli, Salmonella, Pseudomonas aeruginosa, Legionella, poliovirus, Ascaris suis eggs and Cryptosporidium have been evaluated regarding their detection limits and were applied to various residues from German waterworks. Results show that sediments and sludges may contain pathogenic bacteria, viruses and protista. When residues from waterworks are intended to be reused in agriculture or forestry the microbiological quality should therefore be considered.
