If your mini fridge was unplugged and mold grew inside, it's best to exercise caution and prioritize your health. Mold can produce toxins that may be harmful if ingested.
In the case of canned beer, the presence of mold inside the fridge could potentially contaminate the cans, especially if the mold spores have made their way into the cans' openings or if the cans were not sealed tightly. It's essential to check each can for any signs of mold growth or damage.
If you observe any visible mold on the beer cans or suspect that they might have been contaminated, it is safer to discard them. It is not recommended to consume food or beverages that have been in close proximity to mold growth.
When dealing with mold, it's essential to clean and disinfect the mini fridge thoroughly before using it again. You can use a mixture of water and mild detergent or a vinegar solution to clean the affected areas. If the mold growth is extensive or difficult to clean, it might be best to seek professional cleaning services.
Always prioritize your health and safety, and when in doubt, it's better to err on the side of caution and dispose of potentially contaminated items.
