    Shahul,

    Depending on the medium used to count coliforms it is possible that
    pseudomonads are being counted in both assays, which would lead to the very
    similar results you report. This is why it's probably better to do a fecal
    coliform count instead.

      Hello list,

      In fish fillets, if the total bacterial count is as low as 23,500 cfu/gm
    and coliforms are as high as 23,000 per gram what does this indicate? Is it
    contamination, or temperature abuse or lack of cleanliness. Appreciate an
    answer. Thanks.

      Best Regards,

      Shahul Hameed,
