HAZARD ANALYSIS CRITICAL CONTROL POINTS OF FARMYARD PRODUCTION OF WARA «¤?? A POPULAR NIGERIAN CATTLE MILK FOOD

Hazard Analysis Critical Control Points of the production methods of farmyard-processed Nigerian wara were determined using survey studies and oral interviews. Low to moderate sources of microbial hazards included boiling of fresh cowmilk containing Calotropis procera extracts, transfering of moulded wara into boiled cowmilk whey, included addition of crushed Calotropis procera leaves and stem to fresh cowmilk and transporting wara to market for sale and packaging of wara for sale. High sources of microbial hazards were manual milking of several cows to obtain fresh milk samples, and collection of milk samples from different cows in same containers. Significant preventive control of the identified microbial hazards for wara were- keeping of cows in hygienic farmyards, non-milking of mas- titic / ill cows, proper hygiene by food handlers, usage of clean processing materials, wholesome wa- ter samples and hygienic processing conditions. There is need for effective HACCP for quality control and assurance of farmyard-produced Nigerian wara

Effects of Simulated Preparations of Plants used in Nigerian Traditional Medicine on Candida spp. Associated with Vaginal Candidiasis

researchSome Nigerian medicinal plants are popular among traditional producers of phytotherapies in the treatment of sexually related infections. For this study we used modified agar disk, agar spot and agar well-diffusion methods, preparations of simulated crude aqueous and ethanolic extracts of 11 traditionally used medicinal plants for in vitro antimicrobial activities against seventy five strains of Candida species associated with Candida vaginitis and 37 vaginal Lactobacillus species. Candida pseudotropicalis (Castell.) Basgal were minimally inhibited by the plant extracts, while the rate of inhibition of other Candida strains by the ethanolic extracts of the plants were, Ageratum conyzoides L. (44.4 - 66.7%), Anthocleista djalonensis A. Chev. (57.1 - 66.7%), Senna alata (L.) Roxb. (44.4 - 75.0%) Ficus exasperata Vahl. (44.4 - 62.5%), Gliricidia sepium Kunth ex Steud. (64.3%-75.0%) Chromolaena odorata (L.) R.M. King & H. Rob.(57.1%-62.5%) and Rauwolfia vomitoria Afzel. (62.5%). Apart from Aspilia africana (Pers.) C.D. Adams (24.3%) and Ageratum conyzoides L. (35.1%), very low in vitro inhibitory activities of between 5.4% and 16.2% were produced by the medicinal plants against the vaginal Lactobacillus species indicating their ethnophytotherapeutic safety
