Symptoms often start between one and 10 days after exposure.<\/p>\n The tests revealing the E. coli levels were conducted on Friday.<\/p>\n The 31-tonne whale carcass washed ashore on Monday last week, but had been spotted floating in the waters off Perth\u2019s coast in the days prior.<\/p>\n Its presence drew sharks to the coast, and a 3.7-metre great white was caught and tagged just hours after Fisheries officers deployed drum lines off the Floreat Groyne on Tuesday.<\/p>\n Heavy machinery was brought in to shift the carcass, which was taken to a tip over fears towing it out to sea could lead to it breaking up, washing back ashore and drawing even more sharks to the area.<\/p>\n The week\u2019s events reignited debate over WA\u2019s shark mitigation strategy, with retired Fisheries scientist Dr Jim Penn estimating there could be as many as 10,000 great white\u2019s off the WA coast.<\/p>\n Penn said the state\u2019s tagging program was \u201calways a good thing to do\u201d, but it was also expensive, and had already shown the population of sharks on the west coast was separate from those on the east coast.<\/p>\n Related Article \u201cIt\u2019s useful information, and it should be done, [I\u2019m] not suggesting it\u2019s reduced, but a lot of it is needed to be able to get enough DNA samples to do a better estimate [of shark numbers],\u201d he said.<\/p>\n Penn said there was an \u201cincreasing trend\u201d in fatal shark attacks in WA.<\/p>\n \u201cThis year \u2026 the reason I came out of retirement, pretty much, to look at the shark data was the attacks earlier this year, and then one at Sorrento, near where I live,\u201d he said.<\/p>\n \u201cAnd I just find it appalling that that\u2019s still happening.<\/p>\n![\"The](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/10\/1791613486_80_7f2da8585b40e6e7dcb3193b519d3b528b67669110c04509d7dd4571ef5206de.jpeg\")
