Ineffectiveness of propranolol in hypertensive Jamaicans.

the total of 1,161 samples of cream examined in the survey by Barrow and Miller (1967) only 221 and 119 samples respectively satisfied these criteria. The findings described in the present paper suggest that closer attention should be paid to cream, and they emphasize the need for at least clear guidance for cream producers and retailers, and for the introduction of minimum bacteriological standards for samples. We would also urge that the date of production or dispatch, and whether or not heat-treated, should be clearly marked on all retail cream containers.
