This Amendment No. 1 on Form 8-K/A amends and restates in its entirety
the Current Report on Form 8-K, dated January 29, 1997 (and filed February 5,
1997), of Strategic Diagnostics Inc. (formerly known as Ensys Environmental

Item 4. Changes in Registrant's Certifying Accountant.
KPMG Peat Marwick LLP was previously the principal accountant for the
Company. On December 30, 1996, Strategic Diagnostics Inc. ("SDI") merged
with and into the Company. The Company was subsequently renamed "Strategic
Diagnostics Inc." On January 29, 1997, the Company determined to terminate
KPMG Peat Marwick LLP's appointment as principal accountants of the Company
and to engage Arthur Andersen LLP as the Company's independent accountants.
Arthur Andersen LLP had been SDI's independent accountants. The decision to
engage Arthur Andersen LLP and to terminate KPMG Peat Marwick LLP was
subsequently recommended to and approved by the board of directors on
January 29, 1997.
In connection with the audits of the three fiscal years ended December
31, 1995, and during the subsequent interim period up to January 29, 1997,
there were no disagreements with KPMG Peat Marwick LLP on any matter of
accounting principles or practices, financial statement disclosure, or
auditing scope or procedures, which disagreements if not resolved to their
satisfaction would have caused them to make reference in connection with
their opinion to the subject matter of the disagreement.
The audit reports of KPMG Peat Marwick LLP on the consolidated financial
statements of the Company as of December 31, 1995 and 1994, and for each of
the years in the three-year period ended December 31, 1995, did not contain
any adverse opinion or disclaimer of opinion, nor were they qualified or
modified as to uncertainty, audit scope, or accounting principles, except as
follows:
KPMG Peat Marwick LLP's report dated February 16, 1996 refers to the
adoption by the Company of Statement of Financial Accounting Standards No.
115 "Accounting for Certain Investments in Debt and Equity Securities" on
January 1, 1994.
The Company has requested that KPMG Peat Marwick LLP furnish it with a
letter addressed to the Securities and Exchange Commission stating whether or
not it agrees with the above statements. A copy of such letter, dated
February 11, 1997 is filed as Exhibit 16.1 to this Amendment No. 1 to Current
Report on Form 8-K/A.
