1.     I have reviewed this quarterly report on Form 10-QSB of Biomerica, Inc.;

2.     Based on my knowledge, this quarterly 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 quarterly 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
       quarterly report;

4.     The registrant's other certifying officer 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 we have:

       a)     designed such disclosure controls and procedures or caused such
              disclosures 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 quarterly report is being prepared;

       b)     evaluated the effectiveness of the registrant's disclosure
              controls and procedures and presented in this report our

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

       a)     all significant deficiencies and material deficiencies 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 controls over financial reporting.
