We all know (or should know) the prophylactic measures to prevent infection. Sanitize everything, don't splash, don't add water after pitching, etc. But what about after you know a mistake has made but before any sign of infection? Are there any immediate emergency steps that can be taken to lower the risk of infection if, say , you're not sure you remembered to sanitize that wine thief, you just watched a fruit fly dive into your wort, or you just discovered that you didn't fully snap down the ale pale lid several hours after you last had it open? (Asking for a friend about that pale lid priblem)
