Can you provide references for this?

I was only able to find the following article, which suggests only
a 10 times increase, and which can be treated by a "brief period of
hay feeding."

    Grain feeding and the dissemination of acid-resistant Escherichia
coli
    from cattle.
    Diez-Gonzalez F; Callaway TR; Kizoulis MG; Russell JB
    Division of Biological Sciences, Section of Microbiology, Cornell
    University and Agricultural Research Service, U.S. Department
    of Agriculture, Ithaca, NY 14853-8101, USA.
    Science 1998 Sep 11;281(5383):1666-8
    PMID: 9733511 UI: 98404270

    The gastric stomach of humans is a barrier to food-borne
pathogens,
    but Escherichia coli can survive at pH 2.0 if it is grown under
mildly
    acidic conditions. Cattle are a natural reservoir for pathogenic
E.
    coli, and cattle fed mostly grain had lower colonic pH and more
    acid-resistant E. coli than cattle fed only hay. On the basis of
    numbers and survival after acid shock, cattle that were fed grain
    had 10(6)-fold more acid-resistant E. coli than cattle fed hay,
    but a brief period of hay feeding decreased the acid-resistant
    count substantially.

And also this contradictory article:

    Effect of cattle diet on Escherichia coli O157:H7 acid resistance.

    Appl Environ Microbiol 1999 Jul;65(7):3233-5
    PMID: 10388727 UI: 99318686

    The duration of shedding of Escherichia coli O157 isolates by
    hay-fed and grain-fed steers experimentally inoculated with
    E. coli O157:H7 was compared, as well as the acid resistance of
    the bacteria. The hay-fed animals shed E. coli O157 longer than
    the grain-fed animals, and irrespective of diet, these bacteria
    were equally acid resistant. Feeding cattle hay may increase human
    infections with E. coli O157:H7.
