Background : Plant products, including seeds are an important source of vitamins, minerals, proteins, and energy. This study aimed to assess parasitic contaminations in roasted groundnuts,   nabag, and tasali (watermelon seeds) sold by street vendors in Khartoum State, Sudan.    Methods:  The frequency of parasitic contaminations among all crop products was detected by washing the plants with saline, and then conducting an examination using a formal ether   concentration technique (FECT), followed by a saturated sugar floatation technique.    Results:  The detected parasites belonged to two species:  Entamoeba histolytica  (33.3%) and  Giardia lamblia  (15.6%). No helminthic parasites were detected. Mixed contamination of the mentioned parasites was also observed (11.1%). The most contaminated crop was nabag, followed by groundnut, and finally tasali.    Conclusion:  No relation was established between the positivity of samples for parasites and crop type, Khartoum State city, or  seller sex. FECT was more sensitive than the saturated sugar floatation technique as a detection method.
