Biogenic amine production from processed animal and plant protein-based foods contaminated with and .

Unlabelled: The aim of the study was to investigate biogenic amine production in different types of cooked protein foods. The food samples were incubated at varying temperatures (4, 37 and 55 °C) on different microbiological media for 48, 72 and 180 h. Resulting bacteria were isolated and characterized using cultural, biochemical and molecular methods, further screened for production of biogenic amines in decarboxylase broth media supplemented with 0.

Bacteriological safety assessment, hygienic habits and cross-contamination risks in a Nigerian urban sample of household kitchen environment.

Urban household kitchen environment was assessed for safety by determining their levels of indicator bacteria, hygienic habits and risk of cross-contamination. Household kitchens (60) were selected in Warri Town, Nigeria, by the multi-stage sampling technique. Contact surfaces, water and indoor kitchen air were analysed for aerobic plate counts, total and faecal coliforms using Nutrient and McConkey media by swab/rinse method, membrane filtration and sedimentation methods, respectively.

Assessment of the physicochemical and microbiological status of western Niger Delta soil for crude oil pollution bioremediation potential.

The physical, chemical and microbiological characteristics of the soil across the western Niger Delta area of Nigeria were determined to assess its potential for natural remediation of crude oil pollution. The pH (oil-producing area, 6.1 ± 1.

Sociological dimension in the handling habit and sanitary quality of hand-dug well water from oil-producing area of Nigeria.

A previous report showed that the physical and sanitary quality of hand-dug wells from an oil-producing area of Nigeria was poor in spite of the presence of well protective features. The hypothesis that handling habits is associated with the well water quality was therefore, tested. A structured questionnaire with scales for measuring handling habits was administered to 60 female (>18 years) hand-dug well users/owners randomly selected from three towns in the oil-producing area.
