The threats for human health induced by food pests of Plodia interpunctella as reservoirs of infectious microbiota

INTRODUCTION
World-wide distributed pests of Plodia interpunctella occur with increasing frequency also in Poland, in areas where food is prepared and stored, in dwellings, buildings of public use, hospitals. Larvae damage various products causing economic losses. There were no data about microbiota transmission by pests. The aim of our systematic studies firstly conducted in Poland was to explain a role of pests as reservoirs of microbiota and assess health risk induced by them in human environments.


MATERIAL AND METHODS
300 adults and 200 larvae, collected in households and health facilities by traps and directly from products, were examined by light microscopy, in vitro cultivations, molecular techniques; the susceptibility /resistance of microbiota to chemicals was also assessed.


RESULTS
Gram+ bacteriae of genera Enterococcus, Micrococcus, Bacillus, Gram-: Klebsiella, Escherichia, mold fungi: Aspergillus, Penicillium and yeast-like fungi were identified, including strains potentially pathogenic for humans.


CONCLUSIONS
In the European Union countries, the food circulation is audited by the law; chemicals are applied to eliminate P.interpunctella pests causing economic losses. Our successive studies showed that pyralids may generate health problems as food pests and as reservoirs of microbiota. Sources of the pathogenic, drug-resistant strains revealed by us, not identified earlier, may be particularly dangerous for elder persons, with weakened immune system, persons from groups of high risk of infections. The increased awareness of the problem is necessary for more efficacy of preventive measures. A monitoring of consequences of the health risk induced by the pests may supply data useful for adequate practical approach.
