Dog owners in Pendine are being warned to clean up or pay up.
County council environmental enforcement officers carried out a two-day awareness-raising event in the village following complaints of owners not clearing up after their dogs.
Officers spoke to approximately 180 dog walkers during the weekend and all but three had something with them to pick up their dog's mess.
All those spoken to received a goodie bag containing a dog toy, poop scoop bags and pouch to carry their bags as well as information on the diseases dog faeces carry.
The awareness-raising event was held in a bid to educate irresponsible dog owners about the dangers of dog faeces.
All faeces contains bacteria that can cause stomach upsets if ingested, however, the greatest risk to public health from dog faeces is toxocariasis - which can cause epilepsy, asthma and even blindness.
The council has received a number of complaints regarding dog fouling in Pendine, particularly in the green area around the Museum of Speed.
Enforcement officers regularly carry out controls in the county's public places and anyone caught failing to clean up after their dog is issued with a fixed penalty notice of £75.
Failure to pay could lead to prosecution in the magistrates court where the maximum penalty that can be imposed is £1,000.
Area environmental officer Michael Roberts said: "We hope this awareness-raising event will make dog owners in Pendine think twice about leaving their dog mess which is a serious health risk.
"The beach area is used for recreation and leisure by families as well as for walking dogs and it is only fair that people should be able to enjoy it free of dog muck.
"We will be increasing patrols and owners who fail to clean up after their pets will be issued with a fixed penalty."
The council is working hard to deter this type of anti-social behaviour, but it needs the help of the public to identify those responsible.
Anyone who sees someone allowing a dog to foul is asked to note what has happened as soon as possible. Include the time, date and location, a description of the dog and person in charge of the dog. They should then contact Carmarthenshire Direct on 01267 234567.
