Fish pedicures are banned in at least 18 U.S. states and several Canadian provinces, primarily because the procedure makes it impossible to meet basic sanitation standards required of beauty salons. Live fish cannot be disinfected between customers, the water in the tubs cannot be properly cleaned while the fish are in it, and the same fish are reused on person after person. Those three facts create infection risks that state cosmetology boards have decided are simply not worth the novelty.
How Fish Pedicures Work
The procedure involves soaking your feet in a tub filled with small fish called Garra rufa, sometimes known as “doctor fish.” These are freshwater fish native to parts of Turkey and West Asia. They’re omnivores that normally eat plankton, but when food is scarce, they’ll nibble on dead human skin instead. That feeding behavior is the entire basis of the service: the fish exfoliate your feet by eating flaky, dry skin off the surface.
Some spas claim the fish secrete an enzyme called diathanol that promotes skin healing. This remains unproven and is likely a marketing invention.
The Core Sanitation Problem
Every standard pedicure tool, from nail clippers to foot baths, is either sterilized or discarded between clients. Fish pedicures break this model completely. You can’t autoclave a living animal. You can’t add disinfectant to water the fish are swimming in without killing them. And because Garra rufa are expensive to import, salon owners reuse the same fish across dozens or hundreds of customers. Each person’s feet introduce new bacteria into a shared, warm, unsterilized pool.
This is the reason most state bans exist. Cosmetology boards require that all tools and equipment contacting a client’s skin be sanitized between uses. Fish pedicures cannot comply with that rule by definition, so regulators have treated them as inherently non-compliant rather than trying to create a workaround.
Infections Linked to Fish Pedicures
The bacteria found in fish pedicure water and on the fish themselves read like a checklist of skin infection causes. Studies have identified Staphylococcus aureus (including drug-resistant MRSA strains), multiple species of Mycobacterium, Aeromonas, Vibrio vulnificus, and even non-toxigenic strains of the cholera bacterium. Many of these are capable of causing serious soft tissue infections, particularly in people with cuts, cracked skin, or weakened immune systems.
Published case reports describe real patients who developed infections after fish spa visits. These include MRSA skin infections, a type of aggressive skin inflammation called necrotic bullous erysipelas in a patient with undiagnosed diabetes, and multiple cases of Mycobacterium marinum infection, a slow-growing bacterial infection that can take months to respond to treatment. The infections aren’t just transmitted from fish to person. Because the water is shared, bacteria shed by one customer’s feet can infect the next customer. Staphylococcus aureus, in particular, spreads readily through contaminated water.
Nail Damage You Won’t Notice Right Away
Beyond infections, the fish can physically damage your nails. A widely cited case involved a woman in her 20s who developed onychomadesis, a condition where the nail plate separates and sheds, after a fish pedicure. She felt no pain during the session. The damage to her nail matrix only became visible three to six months later, when her nails tried to grow out and couldn’t. Multiple toenails were affected.
The mechanism is subtle: the fish chew on the cuticle area around the nail, which can damage stem cells responsible for producing the nail plate. According to Cleveland Clinic dermatologists, this process leads to gradual lifting and eventual loss of the nail.
The Wrong Fish Can Draw Blood
There’s a second, more alarming problem hiding inside many fish spas. A cheaper species commonly called Chin Chin (or Chinese Chinchin) is frequently substituted for Garra rufa because the two look similar and cost far less to source. The critical difference: Chin Chin fish grow teeth. They can break the skin and draw blood, which dramatically increases infection risk by giving bacteria a direct route into the body.
Customers have no easy way to tell the species apart. If a salon is cutting costs by using Chin Chin fish, you’d likely find out only after something went wrong.
Animal Welfare Concerns
The fish don’t eat human skin because they prefer it. They do it because they’re hungry. Garra rufa only resort to skin-feeding behavior when food is scarce, so the “nibbling” that makes the pedicure work is encouraged by keeping the fish underfed. Veterinary researchers have identified long-term starvation as a major welfare issue in fish spas, noting that almost no information exists on the actual nutritional needs of these fish in captivity.
Beyond starvation, there are concerns about fish being neglected between customers or left in deteriorating water quality. Because individual fish have low financial value but require consistent tank maintenance, some are simply allowed to die and replaced. Several animal welfare organizations cite these conditions as an additional reason to ban the practice.
Where Fish Pedicures Are Banned
At least 18 U.S. states have banned fish pedicures, with the bans coming from state cosmetology boards rather than a single federal regulation. Several Canadian provinces and territories have enacted similar prohibitions. The bans are grounded in existing salon sanitation rules: because the procedure cannot meet the standard requirements for disinfecting equipment between clients, it is treated as a violation.
The United Kingdom took a different approach. Rather than an outright ban, the UK’s Health Protection Agency published guidance on managing the public health risks, effectively leaving the decision to local authorities. In practice, the combination of regulatory hurdles and liability concerns has made fish pedicures rare in the UK as well.
In countries where the practice originated, particularly Turkey, fish spas operate in natural hot spring settings with continuously flowing water, which is a fundamentally different environment from a recirculating salon tub. The risks associated with stagnant, reused water in a commercial salon are not the same as those in a naturally fed thermal pool.
