INFECTIOUS DISEASES IN WASTE
MANAGEMENTTartu
10.3.-11.3.2004
Markku Seuri, FIOH, 2004 2
WASTE
infectious waste from hospitals etc sharps waste solid community waste
– collecting– dumping ground– treatment
waste-water treatment
Markku Seuri, FIOH, 2004 3
GENERAL ASPECTS
microbes found depend on the processes
exposure to a certain microbe in waste-water depend on the prevalence of that disease
Markku Seuri, FIOH, 2004 4
INFECTIOUS WASTE cultures human or animal pathological
waste contaminated material sharps free flowing waste
Markku Seuri, FIOH, 2004 5
LIMITING THE HAZARDS OF INFECTIOUS WASTE
policy– written– approved– based on present knowledge
guidelines– written and simple instructions
training
Markku Seuri, FIOH, 2004 6
SOLID COMMUNITY WASTE
proper handling of waste (sharps) at home
good containers, easy to collect no-touch handling of the waste personal hygiene (smoking, eating,
drinking, clothing) at the dump site; preventing the dust tetanus vaccination
Markku Seuri, FIOH, 2004 7
WASTE-WATER TREATMENT PLANTS
waste-water contains many pathogenic microbes, which are common in that particular community:– hepatitis A– hepatitis C– Salmonella spp– intestinal parasites
waste-water treatment plant workers report more gastrointestinal tract symptoms than controls
Markku Seuri, FIOH, 2004 8
EPIDEMIOLOGY OF WASTE-WATER TREATMENT PLANT
WORKERS
waste-water treatment plant workers seem to have more hepatitis A – depends on the task
they do not experience any increased risk of clinical disease
Markku Seuri, FIOH, 2004 9
WASTE-WATER TREATMENT AND SALMONELLA
Salmonella spp can be found in waste-water
in our study they waste-water treatment plant workers had less antibodies against salmonella than blood donors and reported less salmonellosis than food processing plant workers
could salmonella exposure by inhalation prevent gastrointestinal salmonellosis?
Markku Seuri, FIOH, 2004 10
WASTE-WATER TREATMENT PLANT GI-SYMPTOMS
in several studies more gi-symptoms
– habitual stomach pain– loose or watery stools– varying bowel habits
cause is probably some virus more among the young workers (?) not related to any later disease
Markku Seuri, FIOH, 2004 11
SIMPLE PRINCIPLES FOR WASTE WORK
avoid cuts avoid dust, do not let the waste dry use protective proper protective device in some cases exclusion of some workers
may be considered:– immunocompromised– workers with asthma– workers with allergic rhinitis, conjunctivitis – dermatitis
remember tetanus vaccination
