MPs on the Defence and Internal Affairs Committee of Parliament said Ugandan girls are “auctioned as commodities" and taken to serve as slaves in homes.
About three girls who interfaced with the committee members said they are seriously exploited, mistreated and sometimes sexually abused by their “masters”.
It was also discovered that at least 16 Ugandans have committed suicide in Abu Dhabi this year due to frustrating and inhumane working conditions.
Domestic workers in the Middle East have previously accused authorities of confiscating their travel and work documents.
Uganda had banned the recruitment of domestic workers to Saudi Arabia in 2016 but the ban was lifted a year later after "necessary steps to protect interest of Ugandans" were taken by government.
Last week, Ministry of Gender, Labour and Social Development launched an external labour recruitment monitoring system aimed at curbing exploitation of domestic workers abroad.
The shocking revelation comes months after an exclusive CNN investigation unmasked how African migrants are sold in underground slave markets across Libya for $400.
