Chemical Disinfection

Reconstituted infant milk formulas are considered a food class of high risk because of the susceptibility of the infant population to enteric bacterial pathogens, severe response to enterotoxins, and increased mortality. Twenty infant feeding bottles, contaminated with different levels of enterotoxigenic Bacillus cereus, were subjected in triplicate to a variety of commonly used cleaning and disinfecting procedures. Although thorough cleaning reduced microbial numbers, it did not remove all B. cereus present. Three commercially available disinfection procedures (i.e., one chemical and two thermal) successfully eliminated this organism when the level of contamination was <105 organisms ml−1. However, the chemical disinfection method failed to eliminate enterotoxigenic B. cereus totally at potentially hazardous contamination levels (i.e., ≥105 organisms ml−1) that may be encountered under storage abuse conditions in the home.

The Past

Recent years have brought a reversal in the attitude of the medical profession toward the diagnosis of viral infections. Identification of bacterial pathogens was formerly thought to be faster than identification of viral pathogens. Viral identification was dismissed as being of academic interest or for confirming the presence of an epidemic, because the patient would recover or die before this could be accomplished. In the past 10 years, the goal of virologists has been to present the clinician with a viral identification in a matter of hours. This fast diagnosis has the potential for shortening the patient's hospital stay and preventing the administering of toxic and/or expensive antibiotics of no benefit to the patient.
