Bacteria warnings lifted from Avila, Pismo beaches

County health officials have lifted postings at two local beaches that warned swimmers of high bacteria levels in the water.The county put warning signs out Tuesday at Pismo Beach, just south of the pier, and Avila Beach on Tuesday after testing the day before showed high bacteria levels.Liberty Amundson, a county environmental health specialist, told The Tribune the postings were lifted earlier today.The postings came days after a boater spotted a great white shark between the Harford and Cal Poly piers near Avila Beach. That led to a five-day closure of Avila, Olde Port and Fisherman’s beaches (per a Port San Luis Harbor District policy) that lasted through Monday evening.A surfer spotted a shark about 150 yards south of the Pismo pier Saturday, leading to warning signs being posted there. However, the waters at Pismo were not closed.
