    Abstract: The fecal coliform, <I>Escherichia coli</I>, was inoculated (7 log<SUB>10</SUB> cfu g <SUP>1</SUP>) in 3 commercial baby foods, which were subsequently frozen and stored (-18°C)  for 26 days. Mathematical  model equations were developed describing the effect of freezing and frozen storage on the viable (Pv = (2.83*10<SUP>-8 </SUP>+ (6.18*10<SUP>-8</SUP>*t)) <SUP>1</SUP>) and undamaged populations (Pud = (1.76*10<SUP>-7</SUP> + (4.59*10<SUP>-6</SUP>*t)) <SUP>1</SUP>)<SUP> </SUP>of <I>E. coli</I>. Frozen storage for 1 day reduced the viable and undamaged populations of <I>E. coli</I>,<I> </I>in all baby foods, by about 66.0-91.0 and 66.0-99.0%, respectively. At the same time, the level of damaged cells of <I>E. coli</I> was the highest in all baby foods. After 26 days of frozen storage the viable, undamaged and damaged populations of <I>E. coli</I> declined by about 1.0-3.8 log cfu g <SUP>1</SUP>.
