I did a google on cirticidal and only got two hits in English...one for a pill from a natural food place (for ingestion, not cleaning) and one question on some forum from 2000 with no responses.
I'd say, off hand, it wouldn't be approved for food service. However, if you have used the product and like it it would probably be ok for home use.
As an aside, many new cleaning formulas are including citrus in the formulas. I've used citrus based handcleaners and citrus based air fresheners (from ACE/Truevalue only for the original) and the family really likes the air freshener. I've got a surface cleaner from GFS with orange oils/extracts and it works very well - it's not advertised as antibacterial.
