Two surveys of freezing point depression (FPD) of milk from farms in England and Wales have been undertaken. Both bulk vat samples (non‐authenticated Central Testing samples) and authenticated herd samples were tested and the results compared with those from the survey of authenticated milks carried out in 1977, which has been used as the basis of interpretations of FPD results in BS3095. The results suggested that milk from herds in England and Wales may have a true FPD lower than that recorded in the British Standard and that the action taken for bulk samples with FPD below current thresholds (eg, 530, 525 m°C) may need to be reconsidered.
