“…Lead (Pb) is a chemical element with high density that affects various body systems such as haematological, renal and neurological systems and is mostly harmful in young children [1,26]. Additionally, Pb is regarded as a potentially toxic and carcinogenic metal and has no known physiological functions [1]. The widespread usage of this metal has presented adverse effects such as environmental contamination, human exposure and other public health issues [26].…”

“…Street-vended foods are classified as those foods cooked, prepared and served by vendors in streets and/or other public places and are directly consumed without further preparation [1]. Street foods provide essential nutrients and are a source of energy for millions of consumers worldwide, not only this, but they are also a means of income for many low-income earners around the world [2].…”

“…Street foods provide essential nutrients and are a source of energy for millions of consumers worldwide, not only this, but they are also a means of income for many low-income earners around the world [2]. These foods are inexpensive and readily accessible and as a result, street-vended foods have experienced an economic boom in the past few years [1]. Although street foods offer a great deal of advantages to food security, concerns about their safety and sustainability are far too great to be ignored.…”

Food safety is often threatened by the intended or unintended introduction of contaminants. Street foods are susceptible to microbial, chemical and physical contaminants. Due to their ubiquitous existence in the environment, heavy metals are among the majority of food material contaminants and they are believed to have carcinogenic properties. Heavy metals have been a source of contamination in the informal food value chain mainly due to their bioaccumulation and existence in voluminous amounts. Several factors account for the rate of contamination and the continued failure to prevent it. Carcinogens such as lead and arsenic are often present in high levels in some vended foodstuffs, and their prolonged ingestion could have injurious effects on consumer health. Heavy metal contamination in street-vended foods sometimes occurs as a result of leaching from poorly designed or old and inadequately cleaned utensils. Moreover, aluminium pots used in cooking may leach aluminium ions, especially when acidic foods such as grains and seafood are cooked.

“…ese foods are now popular in developing countries due to economic changes, population growth, and urbanization [44]. Consumption of street foods raised concern about potential food poisoning outbreaks due to improper handling and unhygienic practices among street food vendors [45]. One of the most essential sources of pathogen contamination is vegetable salads which are commonly served along with other foods [46].…”

The safety of humans is of paramount importance in the vegetable production chain. Evidence of microbial and parasitic contamination of these products poses a great threat to consumers. This 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 of people among other factors is the distribution of food in our food systems. The purpose of this study was to draw the attention of 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. This urge for healthy diets coupled with changing dietary habits and human population explosion has therefore accelerated their production. This has resulted in parasitic and microbial contamination gaining grounds in salad vegetables, and as such, a wide range of microbes such as Escherichia coli O157: H7, Listeria monocytogenes, Salmonella spp., Shigella, and Staphylococcus, and parasites such as Giardia lamblia, Entamoeba coli, Entamoeba histolytica, Cystoisospora belli, Toxoplasma gondii, Trichuris trichiura, and Ascaris lumbricoides have been isolated from them. Therefore, major routes for salad vegetable contamination and prevention methods have been pointed out in this review article. The 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. Though consumption of vegetables and salads is encouraged due to their nutritional advantage, appropriate systems should be put in place to ensure their safety.
