Evidence of microbial and parasitic contamination of these products poses a great threat to consumers. is is an emerging issue the world is battling, and it is still in the process of unravelling. However, one of the contributing factors responsible for the rapid spread of these pathogens to millions ofpeopleamongotherfactorsisthedistributionoffoodinourfoodsystems.epurposeofthisstudywastodrawtheattentionof producers, retailers, consumers, and various stakeholders to the occurrence and potential hazard of these organisms, their contamination origin, and food safety protocols. Among the food system, vegetables play a major role, and their consumption has increased as they form a larger portion of daily diets. is urge for healthy diets coupled with changing dietary habits and human population explosion has therefore accelerated their production. is has resulted in parasitic and microbial contamination gaining grounds in salad vegetables, and as such, a wide range of microbes such as EscherichiacoliO157:H7, Listeriamono- cytogenes, Salmonella spp., Shigella, and Staphylococcus, and parasites such as Giardia lamblia, Entamoeba coli, Entamoeba histolytica, Cystoisosporabelli, Toxoplasmagondii, Trichuristrichiura, and Ascarislumbricoides have been isolated from them. erefore, major routes for salad vegetable contamination and prevention methods have been pointed out in this review article. e topic of protective countermeasures will also be covered here in this review. Notwithstanding, several control measures have been reported to be effective and efficient in removing or eliminating pathogens, including treatment of irrigation water and fertilizers, use of disinfectants like vinegar and saltwater, irradiation, ozone, and bacteriophages. ough consumption of vegetables and salads is encouraged due to their nutritional advantage, appropriate systems should be put in place to ensure their safety. 1. Introduction In recent years, there has been an upsurge in vegetable production and consumption throughout the whole world; this is said to be twice its initial production weight of 30 million metric tons in 2018 [1]. In developing countries like Ghana, the initiation of programmes such as the current “Planting for Food and Jobs” by the Government of Ghana has expanded the mass production of fresh vegetables [2]. is was anticipated to increase vegetable consumption by roughly 25% by 2020 [3]. Hence, the consumption of vege- tables globally has increased due to their relatively low cost, high nutritious value, and convenience in preparation. Vegetables are either eaten raw or cooked, and are essential in human nutrition as a result of their nutrient composition such as dietary fibre, minerals (like iron, calcium, zinc, magnesium, Hindawi Journal of Food Quality Volume 2022, Article ID 4141914, 24 pages https://doi.org/10.1155/2022/4141914
