The students of al-Azhar University felt sick after having meals at a dining hall on campus, located in Nasr City in eastern Cairo. The meal contains tuna and vegetables, with rotting tuna suspected to be the cause of poisoning.
The victims have been sent to nearby hospitals for medical treatment, with no deaths reported so far.
After the incident, dozens of angry students blocked a road near the campus on Monday night, and clashed with the police who attempted to disperse the students by firing teargas.
