    Check if it’s Custom post type query: 

     
if ( 'recipe' === $query->get( 'post_type' ) ) { 
	//do your stuff 
}

    Usage scenario: if it’s a query for CPT recipe, it’s not the main query, it’s not admin -> say Hello! before it starts

    add_action( 'loop_start', 'wpdocs_recipes_loop_start' ); 
function wpdocs_recipes_loop_start( $query ){
	if ( !$query->is_main_query() && 'recipe' === $query->get( 'post_type' ) && ! is_admin() ) {
		echo "Hello!";  	
	}
}
