@drcameronjones: 👟 Are second-hand shoes really a fungal risk? I swabbed a pair from a local op shop expecting to find the usual foot-loving fungi... and found nothing. Why? 🤔 Dermatophytes (the fungi linked to athlete’s foot and nail infections) need: 💧 Moisture 🦶 Skin and nails as a food source ⏳ The right conditions to survive Despite common concerns, the bigger risk isn't buying second-hand shoes - it's sharing shoes with someone who has an active fungal infection. Sometimes the science surprises you. #drcameronjones #microbiology #fungi #athletesfoot #secondhandshopping #publichealth #germhunting
