THE grieving family of a Sunshine Coast mother and daughter who died in Bali believe a $6 plate of fish could be to blame. The Courier-Mail can reveal details of the final meal Noelene Bischoff ate with her daughter Yvana - a grand feast at their hotel resort of mahi mahi fish, chicken curry and vegetarian pizza.

'Best friends' die in Bali tragedy 'Best friends', mother and daughter Yvana, 14, and Noelene Bischoff have died in Bali. Police are investigating the final meal the pair shared at the Buddha Bar and Restaurant attached to the Padang Bai Beach resort in Karangasem, as well as medication found in the pair's room. They have ruled out criminal activity. The feast - three days into the 15-day holiday the close pair had excitedly planned - cost the equivalent of just 20 Australian dollars, with the fish the most expensive of the main courses at $6. Restaurant staff from the Padang Bai Beach Resort yesterday insisted Yvana did not eat the fish and that other guests ate the same meal with no problems.

Scombroid poisoning ● Caused by bacterial spoilage and normally occurs in large, dark meat fish such as mahi mahi, tuna and mackerel. This poisoning occurs when a fish is not immediately refrigerated or frozen after being killed. Normal bacteria on the fish creates large amounts of toxins such as histamine and other substances which block histamine breakdown build up in fish. Symptoms include nausea, vomiting, breathing problems and hives. It is rarely fatal and symptoms normally last only a few hours. Ciguatera poisoning ● Caused by eating contaminated fish. The toxins which cause ciguatera poisoning are produced by microscopic sea plants. As smaller fish eat the plants and then those fish are eaten by bigger fish, the toxins accumulate, resulting in high levels in the larger fish. Cooking the fish does not kill the heat-stable toxin. Barracuda are commonly associated with ciguatoxin poisoning, but other fish, including mahi mahi, have also been associated. Though poisoning is relatively common death is rare and occurs in less than 0.1 per cent of cases. Source: National Library of Medicine
