Botulinum bacteria are a soil bacteria. You're much more likely to get botulism from incorrectly prepared root vegetables than from fruits.

Garlic in oil is one of the notorious ones, also baked potatoes in aluminium foil (held at improper temperature), or prison "wine" (often has potato scraps added to boost starch content)

If you go by most stuff on this sub, they're obsessed with drawing breasts. The breast/penis ratio on this sub is way more than one.

Okay, so from the comments you're renting a house and have house mates you don't fully trust. Your bedroom does not have a lock that you can lock when you leave.

The best way would be to replace the bedroom door knob with a keyed entry door knob. Most bedroom knobs only lock from the inside and can be popped really easily with an Allen wrench.

A keyed entry set usually is used on an outside door and you would lock it on the outside with a key and a turn on the inside knob.

If you have a standard door it is super easy to swap. I'd talk to your landlord and get permission to swap the handle in writing.
