The quality and safety of grocery became a consumers’ right that affects directly the quality of life. Thus, the issues referring to the safety of grocery is in the center of attention of the institutions created for protecting the customers’ best interests. The bio milk can be defined as milk with zero quality defects. This means that the milk corresponds to all quality criteria, respectively nutritional, sanitary, bacteriologic, technologic, sensorial, and psycho-social. The microbiological analyses that are described in the paper have the purpose of monitoring the microbiological parameters listed COMMISSION REGULATION (EC) No 1441/2007 of 5 December 2007 amending Regulation (EC) No 2073/2005 on microbiological criteria for foodstuffs and REGULATION (EC) No 853/2004 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 29 April 2004 laying down specific hygiene rules for food of animal origin. The research was made during the validity period of the 3 types of milk that were studied (eco milk, UHT milk, conventional) respectively the product in the first day of validity, in the middle of the validity period and in the last day of validity. The methods used represented both rapid and classic standardized techniques, using media of enrichment, isolation and confirmation, characteristic to each method. After the realised determinations referring to some microbiological characteristics of the conventional and ecological milk, through the validity period were observed some alterations related to the microbiological quality of milk.

ABSTRACTPetis is a pasta-like food made of fresh fish/shrimp. Petis is usually produced by IRT innon sanitary way. These conditions allow the pollution/contamination of the petis production, eitherby microorganisms, physical objects, or chemicals. This study aims to determine the quality ofpetis production in Socah, Bangkalan, Madura.This research is a descriptive research. Data were collectetd by observations andlaboratory tests. There were 3 petis industries in Socah, where we took samples.The results showed that the quality of petis in physical aspects were not qualified, thechemical aspects were good, and microbiological aspects of two samples were not eligible. Sanitaryconditions of the production-sites were less than 53.4%, but the domestic industry‟s score were68%.The final conclusion is that petis production in Socah Madura is ineligible, on physical andmicrobiological aspect. Only in chemical aspect they were eligible. It is recomended to the peopleto be careful in buying any petis from Socah, test the smell and texture before used for dressing infood.Keywords : Petis, Physical, Chemical and Microbiological Quality.

The large temporal and spatial variability of rainwater quality, as well as the relatively small number of tests, makes the preliminary assessment of its economic exploitation difficult. Determining the relationship between the conditions and location of rainwater collection and rainwater quality would help indicate the range of options for rainwater use, as well as the parameters that require improvement. The aim of the presented article is to establish the physical, chemical, and microbiological parameters of different rainwater sources and, from the results obtained, determine the possibilities for its safe use in households. The research was carried out for two years. Samples of rainfall were collected from spring to fall from the following roofing materials: Concrete roof tiles, ceramic roof tiles, galvanized steel sheet, and epoxy-coated terrace. The physical, chemical, and microbiological quality were assessed on the basis of the pH, turbidity, electrical conductivity, the concentration of biogenic compounds, the concentration of chosen elements, the number of Escherichia coli, and the number of fecal streptococci. Significant bacterial contamination, decreased pH, and increased turbidity were identified in the water, depending on the parameters of the roofing washed by the rainfall and the intensity and frequency of precipitation.

Background: Global statistics show that over 1.2 billion people do not have access to potable water and 70% of Nigerians lack access to potable water. Non-availability and/or lack of access to potable water predispose people to preventable life-threatening conditions. This study assessed the physical, chemical, and microbiological quality of sachet and bottled water to generate evidence for planning, policy, and intervention.Methods: The study was a cross-sectional analytic study of the quality of packaged (sachet and bottled) drinking water obtained from consumer households. The potability status of the water samples was assessed by means of qualitative assessments and quantitative laboratory tests. The results were compared to guideline values stipulated by the Nigerian Industrial Standard for Potable Water, NIS 306:2008. Data were analyzed using descriptive and inferential statistics. A p-value of <0.05 was considered statistically significant. The study period was from April 2016 to June 2016.Results: Of the 35.0 bottled water samples, 18.0 (51.4%), 21.0 (60.0%) and 17.0 (48.6%) had their production dates, expiry dates and batch numbers. All 65.0 (100.0%) samples appeared colourless to the naked eye and visible particles were present in 3.0 (4.6%) of the total water samples. The lead content of 7.0 (23.3%) sachet and 1.0 (2.9%) bottled sample exceeded the guideline value for lead. The pH of 16.0 (53.3%) sachet samples and 27.0 (77.1%) bottled samples fell below the recommended limits for pH. Escherichia coli was found in 4.0 (13.3%) and 15.0 (42.9%) of sachet and bottled water samples.Conclusions: The study suggested that sachet and bottled water sold in Nnewi have good physical qualities, but poor chemical and microbiological qualities. More of the microbiological contaminant (E. coli) was present in the bottled water than the sachet water.
