Gentlemen:

At your request we have examined the registration statement on Form S-3 (the
"Registration Statement") to be filed by you with the Securities and Exchange
Commission in connection with the registration under the Securities Act of 1933,
as amended, of 333,333 shares (the "Shares") of Common Stock, $.08 par value per
share, of Biomerica, Inc. (the "Company") held by certain entities named in the
Registration Statement.

In our capacity as counsel, in connection with this opinion, we have examined
originals, or copies identified to our satisfaction as being true copies, of
such corporate documents or records of the Company as we have considered
necessary or appropriate for the opinions hereinafter expressed.

We have assumed for the purposes of this opinion that the signatures on
documents and instruments examined by us as originals are genuine, and that all
documents submitted to us as copies conform with the originals, which facts we
have not independently verified.

On the basis of and subject to the foregoing, and in reliance thereon, and
subject to the qualifications, limitations, assumptions and exceptions set forth
below, we are of the opinion that, as of the date hereof, the Shares are validly
issued, fully paid and non-assessable securities of the Company.

The opinions expressed herein are subject to the following qualifications,
limitations, assumptions and exceptions:

                  (a) The effect of any further amendment, alteration or
adoption of any law, statute, rule, regulation or ordinance, or of any future
judicial interpretation thereof, or of any future amendment or alteration of the
Company's Articles of Incorporation, the Company's Bylaws, or any other
applicable contract, agreement, instrument, judgment or decree.

                  (b) The effect of Section 1670.5 of the California Civil Code
or any other California law, federal law or equitable principle which provides
that a court may refuse to enforce, or may limit the application of, a contract
or any clause thereof which

the court finds to have been unconscionable at the time it was made or contrary
to public policy.

             (c) We express no opinion as to the past, present or future value
of any of the capital stock of the Company.

             (d) We express no opinion as to the Company's compliance or
noncompliance with applicable federal or state antifraud statutes, rules and
regulations concerning the sale of securities.

Our opinion is limited in all respects to the effect on the subject transaction
of the substantive law of the State of Delaware, as currently in effect. Special
rulings of authorities administering such laws have not been sought or obtained.
We assume no responsibility as to the applicability or effect on the subject
transaction of the laws of any other jurisdiction.

Our opinion is expressly limited to the matters set forth above and we render no
opinion, whether by implication or otherwise, as to any other matters related to
the Company.

This opinion is rendered to you solely in connection with the filing of the
Registration Statement with the Securities and Exchange Commission by the
Company and without our prior written consent may not be (a) relied upon by you
for any other purpose, (b) relied upon by any other person or entity for any
other purpose, or (c) copied, reproduced, quoted, referred to, disseminated or
made available to any other person or entity or in any other document, report or
financial statement. We disclaim any obligation to advise you of facts,
circumstances, events or developments which hereafter may be brought to our
attention and which might alter, affect or modify the opinion expressed herein.

We consent to your filing this opinion as an exhibit to the Registration
Statement.

Sincerely,

SOLOMON WARD SEIDENWURM & SMITH, LLP
