My fridge is always 5C (siemens), old model (bosch) was 6C since otherwise back of was creating some ice. No issue with bacteria whatsoever. But we don't keep meat after expiration date (or just freeze it), cheese/diary are usually more than fine well after that, veggies and fruits don't rot in any unexpected manner.
