Fungal Infections & Socks
Socks harbouring Fungal spores
Fungus has been shown to remain in 36% of socks washed at 40 degrees.
Washing at 60 degrees showed 6% remaining with fungal spores.
Socks containing the dermatophyte Trichophyton Rubrum showed 10% could contaminate clean laundry within 1 hour.
Tinea pedis also known as Athlete’s foot is a fungal infection of the skin which is one of the most common skin infections. The most common causes of this infection are Trichophyton Rubrum and Trichophyton mentagrophytes.
Fungal organisms have been shown to survive a long time in socks worn by people with infection.
Research shows that socks can harbour fungal pathogens and contribute to reinfection.
Effects of Washing socks & Fungus
It has been shown contaminated socks washed in a domestic washing machine at 40deg, with 36% of the socks still positive for fungal culture at the end of cleaning and drying cycle.
When the washing was repeated at 60degrees only 6% tested for fungus.
A further study showed socks containing the dermatophyte Trichophyton Rubrum showed 10% could contaminate clean laundry within 1hour
1. Wash socks at 60 degrees if you have or had a fungal infection
2. Consider socks containing anti-microbial fibres
3.Consider changing your socks throughout the day if your feet are sweaty
4. Treat existing fungal infections.
