MEMORANDUM AND JUDGMENT
Petitioner was found guilty of violating the prison disciplinary rule that prohibits possession of narcotics after two packets of a substance concealed inside his underwear tested positive for heroin. The misbehavior report, the testimony of its author, the positive results of a drug test performed on the substance and the testimony of the correction officer who conducted the test provide substantial evidence of petitioner's guilt (see, Matter of Burse v. Goord, 274 A.D.2d 678, 679, 710 N.Y.S.2d 201, 202; Matter of Archie v. Great Meadow Correctional Facility, 243 A.D.2d 808). The record reveals that proper testing procedures were adhered to and that the chain of custody was sufficiently established (see, 7 NYCRR 1010.4; see also, Matter of Harris v. Goord, 268 A.D.2d 933, 934; Matter of Juzwa v. Goord, 264 A.D.2d 920, 921). Contrary to petitioner's contention, the requirement that positive test results be confirmed by a second test applies only to the testing of urine specimens and not when the testing procedures are performed directly on the suspected substance (see, 7 NYCRR 1020.4 [e] [1] [iv]; 1010.4).
We have reviewed petitioner's remaining contentions, including his claim of Hearing Officer bias, and conclude that they are either unpreserved for our review or lacking in merit.
ADJUDGED that the determination is confirmed, without costs, and petition dismissed.
