I, Janet Moore, certify that:

1. I have reviewed this Quarterly Report on Form 10-Q of Biomerica, Inc.;

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 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)) and internal control over financial

reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) 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 subsidiary, is made known to us by others within those entities,

particularly during the period in which this report is being prepared;

      b) designed such internal control over financial reporting, or caused such

internal control over financial reporting to be designed under our supervision,

to provide reasonable assurance regarding the reliability of financial reporting

and the preparation of financial statements for external purposes in accordance

with generally accepted accounting principles;

      c) 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

      d) 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 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 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 the registrant's board of

directors (or other 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.
