Helminths are intestinal worms parasiting warm-blooded animals. They can be found in sandpits because of animal feces like dogs and cats. The XP S 54-207 standard allows us to check your sand by targeting bacteria that would indicate faecal contamination (E. coli and enterococcus) as well as helminth eggs.
Helminth eggs are also checked for in culture substrates (sludge for spreading, market gardening, composts, organic amendments).
Culture substrates must be approved and comply with physical-chemical and microbiological criteria (E. coli, Enterococcus, Salmonella, enteroviruses, viable helminths eggs) as described into the French decree of January 8th (1998) and NF U44-051, NF U44-095 and NF U44-551 standards.
