                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Participants and Administrator of the
Dean Foods Company Investment and Savings Plan

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statement of changes in net assets available for
benefits present fairly, in all material respects, the net assets available for
plan benefits of the Dean Foods Company Investment and Savings Plan (the "Plan")
at December 31, 2000 and 1999, and the changes in net assets available for plan
benefits for the year ended December 31, 2000, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements are the responsibility of the Plan's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of Assets Held
for Investment Purposes as of December 31, 2000 is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

  1.   DESCRIPTION OF PLAN

       The following description of the Dean Foods Company Investment and
       Savings Plan (the "Plan") provides only general information. Participants
       should refer to the Plan document, which can be obtained at Deans Foods
       Company, Franklin Park, Illinois, for a more complete description of the
       Plan's provisions.

       GENERAL

       The Plan is a defined-contribution savings plan that provides retirement
       benefits to full-time salaried and non-union employees of Dean Foods
       Company (the "Company"). Certain union employees whose unions have
       negotiated the benefit are also eligible for retirement benefits under
       the Plan. The Plan is subject to the provisions of the Employee
       Retirement Income Security Act of 1974 ("ERISA").

       A committee appointed by the Board of Directors of the Company is
       responsible for the administration of the Plan. Assets of the Plan are
       held in trust funds maintained at The Northern Trust Company (the
       "Trustee").

       CONTRIBUTIONS

       Participants' contributions are permitted in 1% increments, an amount not
       to exceed 16% of their annual compensation. The Company is required to
       match participant contributions in an amount equal to 50% of the first 6%
       of elective contributions. Effective July 1, 1997, the Company approved a
       resolution to eliminate the annual profit sharing contributions paid
       under the 401(k) plan after the fiscal 1998 contributions, except for
       certain union requirements.

       VESTING

       Participants are eligible to contribute to the Plan at the date of hire.
       Participants vest immediately in their elective contributions, including
       any investment income earned pertaining to such contributions.
       Participants become forty percent vested in Company contributions and
       related earnings after two years of credited service, with vesting
       percentages increasing in twenty-percent increments each subsequent year
       until participants are fully vested after five years of credited service.
       Participants become fully vested in all accounts upon retirement or after
       attaining age sixty-five, or upon termination by reason of death or
       disability.

       PARTICIPANT ACCOUNTS

       Separate accounts are maintained for each participant for Company
       contributions and employee elective contributions. Participants direct
       the investment of all contributions to established funds in 1%
       increments. Plan income is allocated to each participant's account, based
       on the relative value of individual participant accounts to the total of
       all participants' accounts. Forfeitures from terminated participants are
       used to reduce subsequent employer contributions.

       PAYMENT OF BENEFITS

       If a participant's employment with the Company is terminated because of
       retirement at or after he has reached the age of 65, or because of such
       participant's disability or death while in the employment of the Company,
       the balance in his accounts at the accounting date, shall be fully vested
       and nonforfeitable and shall be distributable to the participant, or in
       the event of the participant's death, to his beneficiary, in either a
       lump sum or, at the election of the participant, in a series of
       installments over a period not extending beyond the life expectancy of
       the participant and his spouse.

       PARTICIPANT LOANS

       Participants may borrow from their fund accounts a minimum of $1,000 up
       to a maximum of $50,000 or 50% of their account balance, whichever is
       less. The loans are secured by the balance in the participant's account
       and bear interest at rates that range from 6% to 9%, which are
       commensurate with the prime rate listed in the Wall Street Journal on the
       last business day of the month prior to the month in which the loan
       application is made.

       FORFEITURES

       Forfeited nonvested accounts are used to reduce future employer
       contributions. In 2000, employer contributions were reduced by $395,222
       from forfeited nonvested accounts. Employer contributions of $7,546,746
       include $28,194 of unallocated participant forfeitures at December 31,
       2000.

       ADMINISTRATIVE EXPENSES

       Trustee fees and investment fees of the Plan are paid by the Plan. The
       Company pays legal, audit, and other administrative expenses fees
       associated with the Plan.



  2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       BASIS OF ACCOUNTING

       The financial statements of the Plan have been prepared on the accrual
       basis of accounting.

       RECLASSIFICATION

       Certain reclassifications of prior year financial statement amounts have
       been made to conform with current year reporting.

       USE OF ESTIMATES

       The preparation of financial statements in conformity with generally
       accepted accounting principles requires management to make estimates and
       assumptions that affect the reported amounts of assets, liabilities, and
       changes therein, and disclosure of contingent assets and liabilities.
       Actual results could differ from those estimates.

       CONTRIBUTIONS

       Employer matching and profit sharing contributions are recorded in the
       year accrued by the Company. Employee contributions are recorded in the
       year withheld by the Company from employee payrolls or in the year of
       occurrence for a qualified rollover contribution as defined in Section
       408(d)(3) of the Internal Revenue Code. Provisions of the Plan specify
       that no Company contributions and a maximum of forty percent of any
       participant's contributions may be invested in the Dean Foods stock fund.

       INVESTMENTS

       Purchases and sales of securities, including gains and losses on such
       sales, are recorded as of the settlement date. Pending trade
       sales/purchases are netted against ending investment market values.
       Realized gains or losses resulting from the sale of securities are based
       on the difference between the selling price and the cost of the
       securities, cost being determined on a specific identification basis. In
       accordance with the policy of stating investments at market value, the
       net increase or decrease in the unrealized value of investments for the
       year is reflected in the statement of changes in net assets available for
       plan benefits.

       Market values of investments are based on published market quotations
       where available. Investments in collective funds are stated at the
       year-end unit values as determined by the Trustee, multiplied by the
       number of units owned. Investment income is recorded as earned.

       The Plan presents in the statement of changes in net assets available for
       benefits the net depreciation in the fair value of its investments which
       consists of the realized gains or losses and the unrealized net
       depreciation on those investments for the year.

       PARTICIPANT LOANS

       Loan transactions are treated as a transfer to (from) the investment fund
       from (to) the Participant Loan fund.

  3.   INVESTMENTS

       Effective September 1, 2000, the Plan began offering a S&P 500 index fund
       which is managed by the Trustee. The balanced fund, international fund
       and government fixed fund are managed by Diversified Investment Advisors.
       One-half of the equity fund is managed by ARK Investments, a division of
       Diversified Investment Advisors and the other half is managed by NWQ
       Investment Management Company. The equity growth fund and the small caps
       fund are managed by Mackay Shields and Furman Selz, respectively. These
       funds hold various securities and financial instruments under investment
       guidelines specified by the respective investment advisors.

       The Dean Foods stock fund, which is managed by the Trustee, consists of
       Dean Foods Company Common Stock ($1 par value). During 2000, the Plan's
       investments (including gains and losses on investments bought and sold,
       as well as held during the year) depreciated in value by a net
       $15,639,052 as follows:

  4.   INCOME TAX STATUS

       The Plan administrator has received a favorable determination letter for
       the Plan from the Internal Revenue Service dated February 22, 1996.
       Following the amendments to the Plan relating to contribution percentages
       and employer match, the Plan administrator and the Plan's tax counsel
       believe that the Plan is still designed and being operated in compliance
       with the applicable requirements of the Internal Revenue Code. Therefore,
       they believe that the Plan was qualified and the related trust was tax
       exempt as of December 31, 2000 and 1999. As such, no provision for income
       taxes has been made in the accompanying financial statements.
