The chief executive of Kgapane Hospital near Modjadjiskloof in Limpopo, Benny Moshobane is in hot water after being accused of xenophobia.
Moshobane allegedly referred to five medical doctors from the Democratic Republic of Congo (DRC) at the hospital as "makwerekwere", a derogatory term for non-South Africans.
Moshobane is said to have made the utterances last week during working hours while allegedly under the influence of alcohol.
The matter was forwarded to the provincial department of health, which is investigating.
Phuti Seloba, the department's spokesman, confirmed that the department was investigating the claims by the doctors.
"The doctors wrote a letter to the department and we are probing the allegations. If found to be true, normal processes will be followed against Moshobane," said Seloba.
Spokesman for the doctors, John Nzadi alleged Moshobane arrived at the hospital at 10pm and started shouting at the nurses.
"He accused the nurses and foreign doctors of not doing their work. He told the nurses that doctors on call were supposed to be at the hospital '24/7' waiting for patients rather than patients waiting for doctors. An argument between the nurses and Moshobane ensued.
"Matters came to a head when Moshobane called them names. He said all doctors in the hospital from Malawi were useless 'makwerekweres' who escaped poverty in their countries to the land of milk and honey," said Nzadi.
Moshobane refuted the allegations and said he could not have gone to the hospital drunk.
"These allegations are made by those with a vendetta against me."
