Abstract

This study assesses the effect of different packaging materials on the microbial quality of Africa Locust beans during storage. Locust beans (Dawadawa) also known as iru, among the Yorubas in South-west Nigeria, is a popular condiment used as a taste and flavour enhancer in soup and dishes in Africa. Locust bean is traditionally produced from locust beans seed (Parkia biglobosa) and preserved using different packaging materials before use in order to prolong its shelf life. The Microbiological examination of the produced locust beans was carried out on samples wrapped with different packaging materials such as plastic containers, nylon, and dry banana leaves. The suspected organisms isolated include Salmonella spp, Staphylococcus aureus, Streptococcus lactis, Pseudomonas aeruginosa, Lactobacillus plantarium, Bacillus cereus, Bacillus subtilis, Leuconostoc sp, Escherichia coli and Micrococcus sp. It was observed from this study that locust beans packaged with banana leaves had the highest microbial load, few of which are of public health concern while plastic containers had the least microbial load. It is therefore recommended that locust beans should be produced and packaged with sealed plastic containers to avoid contamination by pathogenic organisms.
