The Public Health Director, from time to time may cause a bacterial examination to be made of such eating and drinking utensils as he may elect to test at any restaurant. In any such test, the resulting bacterial count exceeding 100 per utensil surface area examined shall be considered unsatisfactory. Any three (3) such unsatisfactory results from such tests taken in any restaurant in any sixty (60) day period shall warrant the closing of the restaurant concerned until such time as it has been demonstrated that the conditions causing such unsatisfactory utensil sanitization have been corrected. (§ 8, Chapter IV, Ord. 260, as amended by § 1, Ord. 536, and § 5, Ord. 823, eff. March 1, 1979)
