[Food-related fungal infection risk in agranulocytosis. Mycological control of 273 food items offered to patients hospitalized in sterile units].
In sterile hospital units filamentous fungal infections are an unacceptable risk in patients with prolonged agranulocytosis. The occurrence of 3 successive cases in the Sterile unit of University Hospital of Grenoble prompted us to investigate in all elements of sterile unit, and notably food-processing. Two cooked rice dishes given to these patients were found to contain a substantial amount of Aspergillus fumigatus and were probably responsible for these infections. A more detailed study was carried out to evaluate the degree of food contamination by fungi in sterile unit. The study included 97 cooked dishes which had been sterilized in a 250 degrees oven for 40 minutes and 176 industrially packed foods delivered in single packs (e.g. milk and its derivatives, sweets and drinks). Each foodstuff was mycologically examined 3 to 5 times in different packs according to a procedure used in food analysis laboratories and raised to the standards of mycological examination. In this way, a 3-monthly food testing protocol in sterile unit could be set up. This protocol has a dual purpose: regular checking of the cooked dishes chain and maximum diversification of the dishes.
