An abattoir-based survey was conducted in Addis Ababa from December 2018 to April 2019 with the objectives of determining the prevalence of bovine cysticercosis and the viability of cysticerci. Routine meat inspection was performed on the study animals. Palpation followed by incision of the heart, tongue, triceps muscle, masseter muscle and diaphragm were made to detect the presence of cysts. From the detected cysts, 41 were randomly selected and subjected to viability test. From the total 500 study animals, 14(2.8%) had varying number of cysts. The highest proportion of cyst was observed in the triceps muscle 6(42.8%), followed by heart 3(21.4%), tongue 2(14.3%) and masseter muscle 2(14.3%). There was no cyst observed in the liver or diaphragm. Of the total randomly selected 41 cysticerci, 20(48.8%) were found to be viable while the rest 21(51.2%) cysticerci were found to be non-viable. Sex, breed, age, and body condition of the study animals were found to have no significant association with the occurrence of cysticerci ( > 0.05). Even though routine meat inspection has low sensitivity and usually under-estimates the prevalence of the disease, bovine cysticercosis was found to be prevalent in the study area. Therefore, an appropriate control program involving enforcement of meat inspection, promoting public awareness and improving personal and environmental hygiene should be designed and implemented.

Article Synopsis
- Hyperspectral imaging (HSI) combined with machine learning (ML) offers a promising method for evaluating the freshness of meat by measuring fluorescence, which is closely linked to bacterial density.
- The study introduces a freshness index (FI) as a quantifiable metric for meat freshness, enabling the processing of hyperspectral data to estimate freshness even in unknown states.
- This technology could revolutionize consumer electronics, enhancing devices like refrigerators and smartphones with advanced sensing capabilities for more personalized user experiences.

Bacterial microbiota associated with raw plant-based meat analogue products and their influences on selective enrichment for O157:H7.

Towards fostering a more sustainable food production system in face of the climate change challenge, alternative protein meat-substitute products that are plant-based and free of animal by-products have been gaining attractions from both food manufacturers and consumers. With these so-called plant-based meat analogues (PBMAs) becoming increasingly available at supermarkets, there is very little known about their microbial properties. In this short report, we characterized the bacterial composition of raw plant-based ground meat imitation retail products using 16S rRNA gene amplicon sequencing.

Sheep and goat influence the socioeconomic sustainability of rural communities in tropical countries, but parasitic diseases and in particular are responsible for their low productivity. The occurrence of in most affected regions of the world has been associated to the presence of stray dogs in the grazing area, which play vital roles in the life cycle of the parasite and poor disposal of contaminated and seized offal, organs, and carcasses. The aim of this paper is to systematically review the epidemiology of infection in sheep and goats in the tropics between 2010 and 2022 through the analysis of published qualitative and quantitative data on prevalence, risk factors, organ distribution, and interventions.

Meat inspection is the routine method used to identify cattle infected with Taenia saginata; however, the sensitivity of this method is low. We investigated the prevalence of T. saginata infection in cattle slaughtered in low throughput abattoirs (LTs) in Gauteng province, South Africa, based on meat inspection and serology.
