  Milk has high nutritional values and an important source of protein, minerals, vitamins and fat in human diet. It provides excellent medium for growth of both pathogenic and spoilage microorganism. This study was carried out with the aim of assessing the microbial quality of bulk milk before and after pasteurization, in two different dairy farms in Zaria. Bulk milk samples were collected on daily basis for a period of 30 days during which 30 samples each, of pasteurized and raw milk were collected from each of the farms making a total of 120 milk samples. The both samples of raw milk before pasteurization and post-pasteurization of farm A and B were analyze for total aerobic, coliform plates counts and E. coli isolation rates. Mean results of aerobic plate counts of raw milk for farm A and B before pasteurization were; 5.70 and 6.04 log10 CFU mL-1, respectively. These counts decrease to 3.76 and 4.20 log10 CFU mL-1 after pasteurization of the milk. Similarly, the E. coli isolation rate for farm A and B were; 20 and 53.3%, respectively. These also decrease to 6.7 and 13.3% after pasteurization. In addition, coliform counts also follow similarly trend. The coliform count in farm A and B were; 5.32 and 6.49 log10 CFU mL-1, respectively. The counts decrease to 3.16 and 3.74 log10 CFU mL-1 after pasteurization of the milk. Total coliform and aerobic plates counts before bulk pasteurization in both farms were significantly different (p<0.05), with post-pasteurization values when subjected to paired t-test. The coliform and aerobic plates demonstrated poor hygiene practices and inefficient pasteurization methods in both farms. High isolation rate of E. coli in post pasteurization is an indicative of fecal contamination of the bulk milk indicative of serious public health concern. In conclusion, the present study has demonstrated poor method of pasteurization couple with lack of good hygienic practices such as: proper solid waste management, potable water, cleanliness of milking area and absent of milking installation. These are all factors that contributed to production of poor quality milk in both farms with high coliform, aerobic plates and high isolation rate of Escherichia coli post pasteurization.

  Antibiotics are still deemed necessary for the treatment and prevention of infectious diseases in farm animals intended for food production and to protect public health from food-borne diseases. One possible approach to the resistance problem is the appropriate use of antibiotics for prevention and treatment of infections. A survey was conducted to determine the antibiotic usage in poultry farms and the brand of antibiotics sold over the counter in drug outlets. Reputable poultry farms and drug outlets were identified and questionnaires were administered to 20 poultry farmers. A yes or no type of response was developed to assess level of reported purchase and use of antibiotics without prescriptions. Majority of the respondents (80%) agreed to have purchased an antibiotic without a prescription and the most commonly named antibiotics used by poultry farmers was Tetracycline (Oxytetracycline) 36.5%. It was available in all the drug stores (100%) visited. This was followed by amino glycosides (Neomycin) with 15.2% in poultry farms and 27.2% in drug stores. The widespread access to antibiotics without prescription with resultant inappropriate use, may lead to increased development of resistant strains.

  This study was conducted to assess the soil fertility status and the extent of soil sodicity and salinity in the Kano River Irrigation Project (KRIP), located between latitudes 11°32’N to 11°51’N and longitudes 8°20’E to 8°40’E in the Sudan Savanna of Nigeria. Soil samples were collected from the entire project area using stratified random sampling technique. Questionnaires were used to obtain information on farmers’ soil and water management practices. Soil sodicity was the most serious problem in the area. The exchangeable sodium percentage in the top soil ranged from 3.1 to 34.4 with an average of 14.8, while in the subsoil the range was from 3.1 to 40.6 with an average of 17.5. Soil pH values ranged from 5.6 to 9.5 and 4.8 to 9.6 in the top and subsoil, respectively. About 53% of the farmers interviewed cultivated on their field drains, a practice that has led to the blockage of most of the field drains in KRIP and resulted in waterlogging.
