ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to drain sanitizing articles and more particularly to an improved drain sanitizing article for food processing and preparation environments which will provide prolonged sanitizing in floor drains.
DESCRIPTION OF THE PRIOR ART
The troublesome reoccurrence of food born diseases caused by psychrotrophic, pathogenic micro-organisms has created strong concern within the food process industry and has fueled a search for new environmental sanitation products targeted at these micro-organisms. Public awareness of food born diseases has dramatically increased recently due to the occurrence of epidemics of both listeriosis and salmonellosis.
Between Jan. 1 and Jun. 14, 1985, 86 cases of
Listeria monocytogenes
infection were diagnosed in the area of Orange County, and Los Angeles, Calif. with 29 deaths resulting from ingestion of contaminated Mexican-style cheese. This outbreak followed an earlier 1983 occurrence of 49 diagnosed cases of listeriosis in Massachusetts between June 30 and August 30 with 14 deaths caused by consumption of milk. Between Mar. 22 and Apr. 6, 1985, 5,770 culture-confirmed cases of salmonellosis were reported to the Illinois Department of Public Health caused by an outbreak of milk born
Salmonella typhimurium
. This was the largest number of confirmed salmonellosis cases ever associated with a single outbreak in the United States.
The symptoms of these diseases can manifest a number of different forms. In neonatal infants, the disease often can be characterized by symptoms of sepsis or meningitis. In pregnant women, the disease often takes the form of a puerperal sepsis or non-specific flu-like illness which can result in the premature delivery of stillborn or acutely ill infants. Doyle, M. P.;

; Ann. Rev. Nutr. 1985; Vol. 5, pages 25-41.
The FDA has responded to these recent outbreaks of listeriosis and salmonellosis with expanded plant audits and new test protocols to isolate pathogens in those areas which foster microbiological contaminants. The FDA designed one such procedure for drains, the logic being that pathogens present in the general plant environment would eventually find their way into the drain where growth may occur. In accord with the FDA's renewed focus on this area of the plant environment, there now exists a renewed need for an active continuous drain sanitizer in the food process environment.
SUMMARY OF THE INVENTION
The drain sanitizing article of this invention is a solid drain treatment product designed to sanitize, control odors, clean soil, and control biofilm build-up in drains, troughs, and pits. The drain sanitizing article of this invention is also designed to be effective in environments such as overhead drip and collection pans, or any plant or processing area where water flow causes a general environmental sanitation concern in the dairy and food process industries.
The present invention comprises a sanitizing article for reducing microbiological activity in drain run off areas, including a housing having an inner wall, defining an inner opening in the housing, and an outer wall, the inner and outer walls being joined by a bottom wall and which altogether define an inner cavity for containing an active chemical sanitizing agent in the housing; a tear strip for destructibly removing the outer wall as well as a portion of the bottom wall of the housing, the tear strip being wholly incorporated into the outer wall of the housing; a handle spanning the inner opening of the housing and joined to the inner wall of the housing; and a active sanitizing agent which fills the inner void within the housing.
The sanitizing article of the present invention is intended to be a solid developed for continuous controlled release of active sanitizing agents. The sanitizing article of the present invention includes an active sanitizing agent as well as a housing. The housing functions as a mold for the formation of the active sanitizing agent, a container for safely and continually holding the active sanitizing ingredient during storage as well as application, and a dispenser facilitating in-drain placement. Finally, the invention is intended to provide rapid visual evidence of placement, and dissolution of the active sanitizing agent from within the housing.
