Texas Agriculture Code - AGRIC § 167.102. Entry Power

(a) A commissioner or an inspector, and assistants, may enter public or private property, without a warrant, for the exercise of an authority or performance of a duty under this chapter.

(b) If an inspector or commissioner desires to be accompanied by a peace officer, the inspector or commissioner shall apply for a search warrant to a magistrate of the county in which the property is located. The magistrate shall issue the search warrant on a showing of probable cause by oath or affirmation.

(c) The search warrant shall describe the place to be entered in a reasonable manner that will enable the person in charge of the property to identify the property described, but the warrant is not required to describe the property by field notes or by metes and bounds. If the applicant for the warrant seeks to enter the property to determine whether animals are on the property, the application for the warrant shall state that. If the warrant is obtained for the purpose of seizing or treating animals, the application and the warrant shall describe the animals and give the approximate number of animals. If any of that information is unknown to the applicant, the application and warrant shall state that the information is unknown.

(d) A search warrant issued under this section authorizes the person to whom it is issued to enter the property for the exercise of an authority or performance of a duty under this chapter and to be accompanied by a peace officer and assistants. In addition, the warrant authorizes the peace officer and the assistants to perform any duty authorized by this chapter.

(e) A search warrant issued under this section permits entry and reentry for the purposes of this section for a period of 60 days beginning on the day on which it is issued. After that period, additional search warrants may be issued as often as necessary.
