The distribution channel of meat by-products from the pig farm to the final consumer can include a meat processor, wholesale market, wholesaler, retailer, and butcher shop. Bacterial contamination at any of these steps remains to be a serious public health concern. The aim of this study was to evaluate the distribution channel and microbial characteristics of pig by-products in Korea. Upon eval...

Microbiological and physicochemical characteristics of swimming pools in South Eastern states of Nigeria (Akwa Ibom and Cross River) were investigated. The bacterial isolates included Enterococcus faecalis, Clostridium perfringens, Bacillus cereus and Escherichia coli. Others were Pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris and Staphylococcus epidermidis, while fungal isolat...

The present study was conducted to evaluate the efficacy of nisin on the microbial quality of chicken cutlets. Three levels of nisin viz. 400 I.U/g, 600 I.U/g and 800 I.U/g were incorporated in the formulation to study the effect of nisin on storage quality of chicken cutlets based on various microbiological counts. The chicken cutlets were aerobically packaged in low density polyethylene pouch...

Bacterial whole-cell biosensors were used to measure the concentration of chlortetracycline (CTC) in the feces of pigs. In this study, the Escherichia coli biosensor used has a detection limit of 0.03 mg/kg CTC in pig feces. The tetracycline concentration was correlated with the appearance and maintenance of fecal coliform bacteria resistant to tetracycline. Initially, large quantities of water...

The Limulus endotoxin assay was compared to the standard plate count and total coliform count for assessment of the bacteriological quality of reclaimed wastewater. A total of 48 water samples from an advanced waste treatment plant in Dallas, Tex. were examined by the three techniques. Limulus assays were technically simpler to perform and provided results much sooner than conventional culture ...

BACKGROUND This study investigated the interaction between heterotrophic bacteria and coliform, fecal coliforms, fecal streptococci bacteria in water supply networks. METHODS This study was conducted during 2013 on water supply distribution network in Aq Qala City, Golestan Province, Northern Iran and standard methods were applied for microbiological analysis. The surface method was applied t...

in order to optimize sludge depth in sand drying beds under the climatic conditions of saudi arabia, the effect of initial sludge depth on the fate of pathogens was investigated.the investigation was carried out for one year in al-khobar wastewater treatment plant, where initial sludge depths of 10, 15, 20, 25, 30 and 35 cm were implemented. sludge samples were collected on 0, 1, 2, 4, 7, 14, a...

abstract aims: turbidity in higher than standard levels, indicates failure in the water treatment plant. an electrochemical disinfection process takes place through electricity transition between two or more electrodes. this research aimed to determine the reaction rate of electrochemical process for purification of polluted water. materials & methods: this is a bench scale, experimental study ...
