Nestle says it will stop buying milk from Zimbabwean President Robert Mugabe's wife's farm after facing worldwide boycott threats. The international food company said in a statement Thursday that it had been buying from Grace Mugabe's farm because the cash-strapped national Dairy Board could not. Nestle said they didn't want the milk to go to waste and wanted to boost the country's deteriorating food supply. Nestle says it will now stop as the dairy board has resumed buying milk.
