Amend SB 1685 in SECTION 3 of the bill, in added Section
436.104, Health and Safety Code, by adding new Subsections (d),
(e), (f), (g), (h), and (i) to read as follows:
      (d)  Until Vibrio parahaemolyticus guidelines are formally
adopted into the National Shellfish Sanitation Program, the
department shall follow standards that are at least as stringent as
guidelines of the Interim Control Plan for Vibrio parahaemolyticus
of the Interstate Shellfish Sanitation Conference for the purpose
of designating harvest areas as closed areas related to Vibrio
parahaemolyticus. 
      (e)  The department shall open harvest areas designated as
closed areas due to excessive levels of Vibrio parahaemolyticus in
shellfish meat samples when the levels of Vibrio parahaemolyticus
in the shellfish meat samples return to baseline levels. 
      (f)  The department shall open harvest areas designated as
closed areas due to sporadic non-outbreak illnesses as specified in
the Interim Control Plan when the levels in shellfish meats return
to baseline levels or, if tdh+ serotypes were confirmed as the
cause of the illnesses, when the virulent serotypes of Vibrio
parahaemolyticus are absent in two consecutive samples of shellfish
meats collected from the Vibrio parahaemolyticus sample stations in
the closed area. 
      (g)  The department shall open harvest areas designated as
closed areas due to a confirmed Vibrio parahaemolyticus outbreak
when the department determines that Vibrio parahaemolyticus strains
of virulent serotypes are absent in those situations where 03:K6 or
other tdh+ serotypes were confirmed as the cause of the outbreak.
For purposes of this subsection in Galveston Bay, Vibrio
parahaemolyticus virulent strains shall be considered absent when
25 shellfish meat samples from any delineated harvest area that has
been designated as a closed area do not result in reporting of the
virulent strain that caused the outbreak. 
      (h)  If a second confirmed outbreak of Vibrio
parahaemolyticus illness occurs in an area, the department shall
open a harvest area designated as closed when 50 shellfish samples
do not result in the reporting of the virulent strain that caused
the outbreak. 
      (i)  If harvest areas designated as closed areas as a result
of Vibrio parahaemolyticus cannot be opened as a result of the
sampling under Subsection (f) or (g), the areas may be opened when
environmental conditions develop that are unfavorable for Vibrio
parahaemolyticus growth or when environmental conditions shift to
conditions that are historically unrelated to outbreaks of Vibrio
parahaemolyticus.
