Over the past few days my 18yo daughter has eaten significant amounts of the butter mentioned in the Butter recall today. She has both upper and lower GI symptoms and has just developed an macular rash on her cheeks, similar to slapped cheek syndrome.

All online information I can find says "microbial contamination" - no mention of any specific organism. I have called Coles (the seller), Saputo (the manufacturer) and Food Standards (the regulator) and they all go to voicemail until tomorrow morning. The Poison Center has no more information than "microbial contamination".

Does anyone have any more information on this? If the authorities are so vague in their description, can I exclude Legionella, Brucella and other nasties that need treatment before Food Standards resumes their service tomorrow at 8am?
