                                ----------------

                               GENERAL INFORMATION

         This Proxy Statement is furnished by the Board of Directors of
BIOMERICA, INC., a Delaware corporation (together with its subsidiaries, the
"Company"), in connection with the solicitation of proxies for use at the
Company's Annual Meeting of Stockholders to be held on November 19, 2004, at the
offices of the Lancer Orthodontics, 253 Pawnee Street, San Marcos, California
92069 at 11:30 a.m., and at any and all adjournments thereof (the "Annual
Meeting"). The Annual Meeting has been called for the purposes set forth in the
accompanying Notice of the Annual Meeting of Stockholders (the "Notice"). This
Proxy Statement, and the Annual Report of the Company for the year ended May 31,
2004, will be mailed on or about October 15, 2004, to each stockholder of record
as of the close of business on October 4, 2004.

RECORD DATE AND OUTSTANDING SHARES

         The close of business on October 4, 2004, has been set as the record
date for the determination of stockholders entitled to notice of and to vote at
the Annual Meeting (the "Record Date"). As of September 28, 2004, there was
outstanding and entitled to vote an aggregate of approximately 5,752,431 shares
of the Company's common stock, $0.08 par value per share (the "Common Stock"),
held of record by approximately 984 stockholders. However, brokers and other
institutions hold many shares on behalf of the Company's stockholders and the
Company has been informed that there are approximately 2,094 beneficial owners.

QUORUM

         The presence at the Annual Meeting, in person or by proxy, of the
holders of a majority of the outstanding shares of Common Stock held of record
on the Record Date is necessary to constitute a quorum for the purposes of
electing directors and each other items of business. The holder of each share of
Common Stock held of record on the Record Date is entitled to vote on each
matter to be considered at the Annual Meeting.

VOTES REQUIRED

              Directors shall be elected by a plurality of the affirmative votes
cast at the meeting of stockholders.

VOTING RIGHTS

         Holders of our Common Stock are entitled to one vote for each share
held as of the Record Date.

EFFECT OF ABSTENTIONS AND BROKER NON-VOTES

         If the stockholder or his, her or its broker marks "Abstain" on a duly
submitted proxy card representing such stockholder's shares, or if the
stockholders attend the Annual Meeting in person, but elect not to vote on a
particular proposal or proposals, then such shares will be considered present at
the meeting for purposes of determining the required quorums and will not be
taken into account in determining the outcome of the election of directors.


                                       2


         Brokers holding shares of record for customers generally are not
entitled to vote on some matters unless they receive voting instructions from
their customers. "Broker non-votes" are votes that could have been cast on the
matter in question if the brokers had received their customers' instructions,
and as to which the broker has notified the Company on a proxy form in
accordance with industry practice or has otherwise advised us that it lacks
voting authority. Shares represented by brokers' non-votes (i) will be
considered present at the meeting for purposes of determining the required
quorums and (ii) will not be taken into account in determining the outcome of
the election of directors.

         All votes will be tabulated by the inspector of elections appointed for
the meeting, who will separately tabulate, for the proposal, affirmative and
negative votes, abstentions and broker non-votes.

APPRAISAL RIGHTS

         Under Delaware law, stockholders are not entitled to any appraisal
rights with respect to the approval of any of the proposals described in this
Proxy Statement.

PERSONS MAKING THE SOLICITATION

         The Proxy accompanying this Proxy Statement is solicited on behalf of
the Board of Directors of the Company for use at the Annual Meeting. The
solicitation of proxies is being made only by use of the mails and the cost of
preparing, assembling and mailing these proxy materials will be paid by the
Company. Following the mailing of this Proxy Statement, directors, officers and
regular employees of the Company may solicit proxies by mail, telephone,
telegraph or personal interview. Such persons will receive no additional
compensation for such services. Brokerage houses and other nominees, fiduciaries
and custodians nominally holding shares of the Company's common stock, $0.08 par
value (the "Common Stock"), of record will be requested to forward proxy
soliciting material to the beneficial owners of such shares. The Company will,
upon request, reimburse such parties for their reasonable expenses in forwarding
proxy materials to the beneficial owners.

TERMS OF THE PROXY

         The enclosed Proxy indicates the matters to be acted upon at the Annual
Meeting and provides boxes to be marked to indicate the manner in which the
stockholder's shares are to be voted with respect to such matters. By
appropriately marking the boxes, a stockholder may specify whether the proxy
shall vote for or against or shall be without authority to vote the shares
represented by the Proxy. The Proxy also confers upon the proxy discretionary
voting authority with respect to such other business as may properly come before
the Annual Meeting.

         If the Proxy is executed properly and is received by the proxy prior to
the Annual Meeting, the shares represented by the Proxy will be voted. Where a
stockholder specifies a choice with respect to the matter to be acted upon, the
shares will be voted in accordance with such specification. Any proxy which is
executed in such a manner as not to withhold authority to vote for the election
of the specified nominees as directors shall be deemed to confer such authority.
A Proxy may be revoked at any time prior to its exercise by giving written
notice of the revocation thereof to Ms. Janet Moore, Secretary, Biomerica, Inc.,
1533 Monrovia Avenue, Newport Beach, California 92663, by attending the meeting
and electing to vote in person, or by a duly executed Proxy bearing a later

DIRECTORS

         The Company's Bylaws give the Board of Directors ("the Board") the
power to set the number of directors at no less than three (3) or more than nine

         The following table sets forth the name and current age of each nominee

recommended nominees from a stockholder owning more than 5% of the Company's
stock for at least one year.

The Board recommends a vote for the election of each of the nominated directors.

         The Board of Directors regularly assesses the appropriate size of the
Board of Directors and whether any vacancies on the Board of Directors are
expected due to retirement or otherwise. In the event that vacancies are
anticipated or otherwise arise, the Board utilizes a variety of methods for
identifying and evaluating director candidates. Candidates may come to the
attention of the Committee through current directors, professional search firms,
stockholders or other persons.

         Once the Board has identified a prospective nominee, the Board will
evaluate the prospective nominee in the context of the then current composition
of the Board of Directors and will consider a variety of other factors,
including the prospective nominee's business, technology and industry, finance
and financial reporting experience, and other attributes that would be expected
to contribute to an effective Board of Directors. The Board seeks to identify
nominees who possess a diligent range of experience, skills, areas of expertise,
industry knowledge and business judgment. Successful nominees should have a
history of superior performance or accomplishments in their professional
undertakings and should have the highest personal and professional ethics and
values. The Board does not evaluate stockholder nominees differently than any
other nominee.

         Our Board will consider stockholder nominations for directors if we
receive timely written notice, in proper form, of the intent to make a
nomination at a meeting of stockholders. To be timely, the notice must be
received within the time frame discussed below in this Proxy Statement under the
heading "Stockholder Proposals." To be in proper form, the notice must, among
other matters, include each nominee's written consent to serve as a director if
elected, a description of all arrangements or understandings between the
nominating stockholder and each nominee and information about the nominating
stockholder and each nominee.

Robert Orlando are "independent" within the meaning of Nasdaq Marketplace Rule
4200(a)(15) as adopted by the Nasdaq Stock Market, Inc. ("Nasdaq"). Mr. Zack
Irani and Ms. Janet Moore were not deemed to be "independent" because of their
respective employment relationships with us. Mr. Allen Barbieri was deemed to be
"independent" until April 2004, at which time he became the Chief Executive
Officer of our subsidiary, Lancer Orthodontics, and therefore is now deemed not
to be independent.

COMPENSATION COMMITTEE

         The Compensation Committee is responsible for assisting the Board of
Directors in discharging its responsibilities regarding the compensation of our
employees and directors. The specific duties of the Compensation Committee
include, among other matters: reviewing and approving executive compensation;
evaluating our executive officers' performance; setting the compensation levels
of our executive officers; setting our incentive compensation plans, including
our equity-based incentive plans; and making recommendations to our Board of
Directors regarding our overall compensation structure, policies and programs.
In fiscal 2004 the compensation committee was comprised of Dr. Robert Orlando
and Ms. Janet Moore. Currently, the compensation committee is comprised of Mr.
Allen Barbieri and Dr. Francis Cano. One compensation committee meeting was held
during the fiscal year ended May 31, 2004.

AUDIT COMMITTEE

         The Audit Committee is responsible for overseeing our accounting and
financial reporting processes and the audits of our financial statements. In
addition, the Audit Committee assists the Board of Directors in its oversight of
our compliance with legal and regulatory requirements. The specific duties of
the Audit Committee include, among others: monitoring the integrity of our
financial process and systems of internal controls regarding finance, accounting
and legal compliance; selecting our independent auditor; monitoring the
independence and performance of our independent auditor; and providing an avenue
of communication among the independent auditor, our management and our Board of
Directors. The Audit Committee has the authority to conduct any investigation
appropriate to fulfilling its responsibilities, and it has direct access to all
of our employees and to the independent auditor. The Audit Committee also has
the ability to retain, at our expense and without further approval of the Board
of Directors, special legal, accounting or other consultants or experts that it
deems necessary in the performance of its duties.

         The Audit Committee met one time during fiscal 2004. The members of the
Audit Committee are Mr. Barbieri, Dr. Orlando and Dr. Cano. Our Board of
Directors has determined that Dr. Orlando and Dr. Cano are independent within
the meaning of Nasdaq Rule 4200(a)(15) as well as the enhanced independence
standards contained in Nasdaq Rule 4350(d) that relate specifically to members
of audit committees.

REPORT OF THE AUDIT COMMITTEE

         The Audit Committee oversees the Company's financial reporting process
on behalf of the Board of Directors. Management has the primary responsibility
for the financial statements and the reporting process including the systems of
internal controls. In fulfilling its oversight responsibilities, the Committee
reviewed the audited financial statements in the Annual Report with management
including a discussion of the quality, not just the acceptability, of the
accounting principles, the reasonableness of significant judgments, and the
clarity of disclosures in the financial statements.

                                       8


         The Committee reviewed with the independent auditors, who are
responsible for expressing an opinion on the conformity of those audited
financial statements with generally accepted accounting principles, their
judgments as to the quality, not just the acceptability, of the Company's
accounting principles and such other matters as are required to be discussed
with the Committee. The Committee has discussed with the independent auditors
the auditors' independence from management and the Company including the matters
in the written disclosures required by the Independence Standards Board and
considered the compatibility of non-audit services with the auditors'
independence.

         The Committee discussed with the Company's independent auditors the
overall scope and plans for their audit. The Committee meets with the
independent auditors, with and without management present, to discuss the
results of their examinations, their evaluations of the Company's internal
controls, and the overall quality of the Company's financial reporting.

         In reliance on the reviews and discussions referred to above, the
Committee recommended to the Board of Directors (and the Board has approved)
that the audited financial statements be included in the Annual Report on Form
10-KSB for the year ended May 31, 2004 for filing with the Securities and
Exchange Commission. The Committee and the Board have also recommended the
selection of the Company's independent auditors.

COMPENSATION OF DIRECTORS

         Although not prohibited by the Company's Bylaws, directors receive no
direct payment for their services as directors, but they have been, and may in
the future be, granted options to purchase the Company's securities. The
compensation of directors is subject to review and adjustment from time to time
by the Board of Directors.


SECTION 16(a) - BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's executive officers, directors and persons who beneficially own more
than 10% of the Company's stock, to file initial reports of ownership and
reports of changes in ownership with the Securities and Exchange Commission.
Executive officers, directors and greater than 10% beneficial owners are
required by applicable regulations to furnish the Company with copies of all
Section 16(a) forms they file.

         Based solely upon a review of the copies of such forms furnished to the
Company and information involving securities transactions of which the Company
is aware, the Company believes that during the fiscal year ended May 31, 2004,
all Section 16(a) filing requirements applicable to its executive officers,
directors and greater than 10% beneficial stockholders were complied with.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         The Company leases its primary facility under a non-cancelable
operating lease expiring October 31, 2005, with monthly lease rent of $15,000
with a 3% increase effective September 1, 2003. The facilities are owned and
operated by four of the Company's shareholders one of whom is an officer and
director. During fiscal 2004 the Company consolidated some of its operations and
the landlords agreed to take back the space no longer needed by the Company and
to reduce the rent accordingly. The landlords also agreed not to institute the
3% increase as required in the lease. The current monthly rent is $12,940. In
May and June 2003 the Company issued 60,000 shares of Biomerica restricted
common stock plus warrants to purchase an additional 60,000 shares of Biomerica
restricted common stock at the purchase price of $0.25 for payment of $15,000 in
accrued rent. Management believes there would be no significant difference in
the terms of the leases if they were with a third party. Total rent expense for
this facility was approximately $150,000 and $165,000 during the years ended May
31, 2004 and 2003, respectively.


NOTES PAYABLE -SHAREHOLDER

         The Company entered into an agreement for a line of credit agreement on
September 12, 2000 with a shareholder whereby the shareholder would loan to the
Company, as needed, up to $500,000 for working capital needs. The line of credit
bore interest at 8%, was secured by accounts receivable and inventory, and
expired September 13, 2003. In March 2004 the Company signed a note payable for
the principal and interest due at that time of $313,318 and agreed to a
forbearance of any payments for the length of the agreement. A warrant for
40,000 shares of restricted common stock exercisable at a price of $.51 per
share was awarded as compensation for the forbearance. The note payable is
secured by all the Company's assets except for the Lancer common stock that it
owns. The note was due September 1, 2004. There was $313,318 of outstanding
principal and $5,356 of interest payable under this line of credit at May 31,
2004.

         During 2004 and 2003, the Company incurred approximately $25,438 and
$29,466, respectively, in interest expense related to the shareholder line of
credit and loan.

                                       11


         The Company and the stockholder are currently finalizing the terms of
an addendum to these agreements which provides for monthly payments of principal
and interest and an extension of the due date on the note for one year.

         During 2004 and 2003, a shareholder loaned the Company $4,000 and
$10,000, respectively. During June 2003 the $10,000 loan was repaid in the form
of Company common stock at the price of $.25 per share. Interest for the fiscal
year ended May 31, 2004 was $283. At May 31, 2004, $1,555 was owed in interest
payable on the two loans.


RENT EXPENSE

         Biomerica, Inc. leases facilities from a partnership owned, in part, by
an officer/director/shareholder of the Company. Rent expense of approximately
$150,000 and $165,000 was incurred during 2004 and 2003, respectively, for this
lease. A further expense of approximately $7,000 has been included in accounts
payable representing late fees and interest payable on outstanding rent. Rent
payable at May 31, 2004 was approximately $119,000 and has been included in
accounts payable in the consolidated balance sheet.


ACCRUED COMPENSATION

         Two officers, who are also shareholders of the Company agreed to defer
payment of a portion of their salaries. At May 31, 2004 approximately $177,100
of deferred officer's salary is included in accrued compensation in the
accompanying consolidated financial statements.

         Approximately $121,000 of the total accrued compensation is due to the
former chief executive officer's estate.


PRIVATE PLACEMENT

         During fiscal 2004 the Chief Executive Officer purchased 100,000 shares
of restricted common stock with 100,000 warrants at a purchase price of $0.25
per share. The shares were paid for with $5,000 cash, $10,000 in reduction of
note payable to him and $10,000 reduction in accrued salary.

         During fiscal 2003 the Chief Financial Officer agreed to purchase
18,000 shares of restricted common stock with 18,000 warrants at a purchase
price of $0.25 per share. The shares were paid for with a reduction of rent
payable due to the officer, and were issued in fiscal 2004.


INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

         The Company's independent auditors for the fiscal years ended May 31,
2003 and 2002 were BDO Seidman, LLP ("BDO"). Effective May 29, 2004, the
Company, upon approval of the audit committee of the Board of Directors of the
Company, dismissed BDO. Effective May 29, 2004 the Company, upon approval of the
audit committee of the Board of Directors, approved the appointment of PKF,
Certified Public Accountants, A Professional Corporation, San Diego, as the
Company's independent auditors for the fiscal year ended May 31, 2004.

         BDO last reported on the Company's financial statements on August 11,
2003. The report, which covered the two fiscal years ended May 31, 2003, was
modified for going concern. BDO expressed substantial doubt as to the Company's
ability to remain a going concern.

         The auditors' report of BDO Seidman on the consolidated financial
Statements of Biomerica, Inc. and subsidiaries as of and for the years ended May
31, 2003 and 2002 contained the following paragraph:

                                       12


"The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. The Company has historically
reported net losses and negative cash flows from operations, which raise serious
liquidity concerns. Management estimates that its available cash resources as of
May 31, 2003 along with cost reductions will be sufficient to fund planned
operations through May 31, 2004. These operating and liquidity issues, amongst
other concerns, raise substantial doubt about the Company's ability to continue
as a going concern. Management's plans in regard to these matters are described
in Note 1 to the accompanying consolidated financial statements. The
consolidated financial statements do not include any adjustments relating to the
recoverability and classification of asset carrying amounts or the amount and
classification of liabilities that might result should the Company be unable to
continue as a going concern."

         The change of independent accountants was ratified by the Board of
Directors of the Company on May 29, 2004.

         During the two fiscal years ended May 31, 2003 and the subsequent
interim period through May 29, 2004, there were no disagreements between the
Company and BDO on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which, if not resolved, to
BDO's satisfaction, would have caused it to make reference to the subject matter
of the disagreement in connection with its report.

         During the two fiscal years ended May 31, 2003 and subsequent interim
period through May 29, 2004, there have been no reportable events (as defined in
Regulation S-K Item 304(a)(1)(v)).

         During the two fiscal years ended May 31, 2003 and the subsequent
interim period through May 29, 2004 BDO did not advise the Company that the
internal controls necessary for the Company to develop reliable financial
statements do not exist.

         During the two fiscal years ended May 31, 2003 and the subsequent
interim period through May 29, 2004, BDO did not advise the Company that any
information had come to their attention which had led them to no longer be able
to rely on management's representation, or that had made BDO unwilling to be
associated with the financial statements prepared by management.

         During the two fiscal years ended May 31, 2003 and the subsequent
interim period through May 29, 2004, BDO did not advise the Company that the
scope of any audit needed to be expanded significantly or that more
investigation was necessary.

         During the two fiscal years ended May 31, 2003 and the subsequent
interim period through May 29, 2004, BDO did not advise the Company that there
was any information which the accountants concluded would materially impact the
fairness and reliability of either (i) a previously issued audit report or the
underlying statements, or (ii) the financial statements issued or to be issued
covering the fiscal period(s) subsequent to the date of the most recent
financial statements covered by an audit report (including information that,
unless resolved to the accountant's satisfaction, would prevent it from
rendering an unqualified audit report on those financial statements).

         The Company engaged PKF, Certified Public Accountants, A Professional
Corporation (San Diego) ("PKF") as its new independent accountant on May 29,
2004. Prior to May 29, 2004, the Company had not consulted with PKF regarding
(i) the application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's financial statements, and no written report or oral advice was
provided to the Company by PKF concluding there was an important factor to be
considered by the Company in reaching a decision as to an accounting, auditing
or financials reporting issue; or (ii) any matter that was either the subject of
a disagreement, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K
and the related instructions to Item 304 of Regulation S-K, or a reportable
event, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K.

                                       13


         It is expected that a representative of the independent registered
accounting firm of PKF San Diego, the Company's auditor for the fiscal year
ended May 31, 2004, and for the current fiscal year, will be present at the
Annual Meeting to respond to appropriate questions or to make a statement if he
or she so desires.
