The Health Ministry has ordered all blood banks to dispose of donations from Ethiopian immigrants, Channel 2 reported on Tuesday evening.
According to a representative from one of the blood banks, there is nothing preventing Ethiopians from donating blood, but their donations are not used due to the prevalence of AIDS in African countries.
She said that the blood samples were frozen, however, rather than thrown away.
This latest incident recalls a similar scandal from ten years ago, when it was discovered that Magen David Adom was accepting blood donations from Ethiopians and then discarding them.
In Israel, as in most countries, blood donors must fill out a form detailing whether they have lived in AIDS-infested countries.
