Temperatures of water exemplifying liquid foods in household refrigerators were determined. The mean of a.m. and p.m. observations with 11 different refrigerators was 3.6 C. Only two refrigerators showed a significant difference between a.m. and p.m. temperatures. Both the variance and range were surprisingly low in view of the limited previous published data. These results indicated household refrigerators have received too much condemnation for inadequate protection of quality of foods.
