Summary
New Spanish regulations mandate strict microbiological standards for bottled mineral water, ensuring safety by requiring the absence of pathogens and specific bacteria like Pseudomonas aeruginosa.
Area of Science:
- Microbiology
- Food Safety
- Environmental Health
Background:
- Spanish legislation, Decree 607/13th March 1975, outlines microbiological standards for bottled mineral waters.
- Previous regulations focused on general microbial absence, but lacked specific pathogen targets.
Purpose of the Study:
- To detail the microbiological standards for bottled mineral waters in Spain.
- To highlight the inclusion of Pseudomonas aeruginosa as a key indicator organism.
Main Methods:
- Description of technical methods used for microbiological investigation of mineral waters in Spain.
- Emphasis on techniques for differentiating Pseudomonas aeruginosa using fluorescent pigments.
Main Results:
- Mandatory absence of parasites and pathogenic microorganisms.
- Strict limits for fungi, coliforms, E. coli, Streptococcus, and Clostridium sulphite reducing bacteria.
- First-time requirement for the total absence of Pseudomonas aeruginosa in bottled mineral water.
Conclusions:
- The updated Spanish regulations establish comprehensive microbiological safety standards for bottled mineral water.
- The specific exclusion of Pseudomonas aeruginosa enhances consumer protection and water quality assurance.
