Cryptosporidium and other Swimming Pool Illnesses in Spain and the Balearics

Dated:   

  • Were you ill on holiday in Spain with a gastric holiday illness?
  • Was there an outbreak of holiday illness at your hotel?
  • Suffered Cryptosporidiosis in Majorca, Ibiza or the Canary Islands?
  • Seeking compensation for cryptosporidium on holiday?
  • Dirty or cloudy swimming pool at your hotel?
  • Professional compensation claims experts are at hand

Hotel swimming pools are exposed bodies of water and are thus subject to contamination by bacteria, parasites and viruses. The contamination can be carried into the water by swimmers, by the environment (eg wind, rain, dust) and by birds.

Dirty Swimming Pools can lead to holiday illnesses eg cryptosporidium

Over the past 5 years there has been a dramatic increase in the number of infectious diseases caught from swimming in dirty pool water in the Balearic Islands. Indeed, certain strains of bacteria and parasites have built up resistance to the chlorine traditionally used to disinfect hotel swimming pools. Some bugs are destroyed very slowly. Consequently, there has been an increasing demand for alternative methods able to quickly and effectively destroy disease carrying organisms.

Holiday Illness Fact:


Diseases that can result from infected pool water include: Dysentery, Amoebic dysentery, Cholera, Typhoid, Hepatitis A, Giardiasis, Cryptosporidiosis, Salmonellosis, Shigellosis, and Dermatitis.

Unfortunately, it is impossible to prevent bacteria and viruses from entering pool water. In swimming pools used by a high volume of holiday makers, the amount of contaminants entering the water is inevitably high.

Hotels often have faecal accident policies in place to deal with contamination and to warn holiday makers about the risks of faecal contamination. Travellers’ who are ill or recovering from a bout of gastric illness are requested to abstain from swimming, but many ignore this plea.

The traditionally disinfectant, chlorine, often breaks down quickly in the presence of high contamination due to the effects of the sun's UV rays and heat. 50% of the pools which have chlorine levels above 2.0 ppm will still have both E. Coli and Pseudonomas bacteria present. With this in mind, many hotels abroad over-chlorinate swimming pool water in the hope that bacteria and parasites can be destroyed.

This creates another danger - chlorine too, can cause serious health problems to the skin and its overuse should be avoided at all costs.

Modern techniques of pool filtration are required and it is essential that the pool filtration system and water treatment plant is adequate for its purpose and the capacity of the pool to effectively destroy potentially harmful bacteria, parasites and algae before they can strike.

Holiday Illness Fact:


Chlorine can often take 4 days to eliminate the effect of Cryptosporidium parvum, the parasite which causes severe gastric illness. The parasite can be transmitted through swimming pool water, despite a balanced pool chemistry and free chlorine levels of 2.oppm.

A total reliance on chlorine for swimming pool disinfection is foolish in the light of modern research. There is unequivocal proof of the efficacy of modern techniques using UV filtration, bromide and other pool water treatments that can supplement chlorine to create safer pool water.
