                          CERTIFICATION
                          -------------


I, Jasper B. Sanfilippo, certify that:

1.	I have reviewed this Annual Report on Form 10-K of John B.
        Sanfilippo & Son, Inc. for the fiscal year ended June 26, 2003;

2.   	Based on my knowledge, this report does not contain any
        untrue statement of a material fact or omit to state a material
        fact necessary to make the statements made, in light of the
        circumstances under which such statements were made, not
        misleading with respect to the period covered by this report;

3.   	Based on my knowledge, the financial statements, and other
        financial information included in this report, fairly present in
        all material respects the financial condition, results of
        operations and cash flows of the registrant as of, and for, the
        periods presented in this report;

4.   	The registrant's other certifying officer(s) and I are
        responsible for establishing and maintaining disclosure controls
        and procedures (as defined in Exchange Act Rules 13a-15(e) and
        15d-15(e)) for the registrant and have:

        (a)  Designed such disclosure controls and procedures, or caused
        such disclosure controls and procedures to be designed under our
        supervision, to ensure that material information relating to the
        registrant, including its consolidated subsidiaries, is made
        known to us by others within those entities, particularly during
        the period in which this report is being prepared;

        (b)  Evaluated the effectiveness of the registrant's disclosure
        controls and procedures and presented in this report our
        conclusions about the effectiveness of the disclosure controls
        and procedures, as of the end of the period covered by this
        report based on such evaluation; and

        (c)  Disclosed in this report any change in the registrant's
        internal control over financial reporting that occurred during
        the registrant's most recent fiscal quarter (the registrant's
        fourth fiscal quarter in the case of an annual report) that has
        materially affected, or is reasonably likely to materially
        affect, the registrant's internal control over financial
        reporting; and

5.   	The registrant's other certifying officer(s) and I have
        disclosed, based on our most recent evaluation of internal
        control over financial reporting, to the registrant's auditors
        and the audit committee of the registrant's board of directors
        (or persons performing the equivalent functions):

        (a)  All significant deficiencies and material weaknesses in the
        design or operation of internal control over financial reporting
        which are reasonably likely to adversely affect the registrant's
        ability to record, process, summarize and report financial
        information; and

        (b)  Any fraud, whether or not material, that involves
        management or other employees who have a significant role in the
        registrant's internal control over financial reporting.
