Drinking curdled milk in coffee, if it’s fresh and the curdling is due to acid in the coffee, is generally safe but might be unpleasant in texture and taste. However, if the milk is curdled because it's spoiling, it’s best to avoid consuming it to prevent foodborne illness. Always check the freshness of the milk before adding it to hot coffee, as heat can accelerate the curdling process, especially if the milk is on the brink of turning bad.
