ASSESSMENT OF MICROBIAL LOAD IN BRANDED DRIED TEA MARKETED IN SMALL POUCHES | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

Tea is the most frequently consumed drink in the world after wine, being an aromatic beverage typically prepared by pouring hot or boiling water over cured Camellia sinensis leaves. Microbial contamination of tea powder can occur frequently due to mismanagement and unhygienic conditions during tea storage and processing. Serious health risks can result from this microbial contamination. The goal of the study is to perform a microbial analysis of 10 samples of commercially available tea pouches to investigate the presence of different microorganisms, including fungi, in tea powder samples. According to the report, 80 percent of the samples (8 out of 10) of branded tea sold in small pouches and the number of bacterial colonies ranged from 2-68 CFUs were found to have a bacterial load; sample no 7 showed the highest bacterial count of 68 CFUs. Bacillus was the bacteria that was widely observed and 60% of the sample (6 out of 10) pouches also had fungal load. This research serves as an eye opener to tea addicts and makes them aware of the risk during the shelf time of rising microbial load.

Determination Of Chemical And Gross Organic Pollutant Levels In Leachates From Approved Waste Dumpsites, Port Harcourt Metropolis, Rivers State, Nigeria

This study was aimed at the determination of chemical and gross organic pollutants levels in leachates from some selected and government approved dumpsites in Port Harcourt metropolis. Leachates from the 3-selected dumpsites were analyzed and compared with the seasons, controls and established standards using descriptive statistical designs. Integrated samples were collected during both wet and dry seasons and analyzed for DO, BOD, ORP, Salinity and pH. The use of 2-way ANOVA, t-test, graphs and mean variation were applied to explain trend and variations. The results show that there was no significant difference in temporal dimension (seasonally) but high level spatial variation (stations) in most parameters occurred. Most chemical/ gross organic pollutants showed higher level concentrations during the dry season. Though some of the parameters were relatively low compared to standard limits; the study revealed that these dumpsites remain major polluting sources to the surrounding surface and ground water regimes. In order to recover these dumpsites from acute contamination, state government should ensure the use active remediation processes and treatment to reduce the effects of pollution to the ecosystem.
