Preface
The consequences of unintended microbial growth in foods are hazards due to the presence of
pathogenic microorganisms or economic losses due to spoilage microorganisms. Preservation
technologies are designed to protect foods from the effects of microorganisms and inherent dete-
rioration. Microorganisms in foods may be inhibited or inactivated by physical methods (e.g., heat,
cold, reduced water activity) or through application of antimicrobial compounds. Food antimicro-
bials, including chemical sanitizers, may be broadly defined as chemical compounds present in or
added to foods, food packaging, food contact surfaces, or food processing environments that inhibit
the growth of, or inactivate, pathogenic or spoilage microorganisms. Historically, the primary
function of food antimicrobials has been to prolong shelf life and preserve quality through the
inhibition of spoilage microorganisms. In the past 10 to 15 years, however, antimicrobials have
been increasingly utilized as a primary intervention for the inhibition or inactivation of pathogenic
microorganisms in foods. This function becomes increasingly important as food processors search
for more and better tools to improve food safety.
Antimicrobials continue to be one of the most important classes of food additives. Research
on antimicrobials, especially naturally occurring compounds, has increased dramatically in the past
10 to 15 years. The primary incentive for searching for effective antimicrobials among naturally
occurring compounds is to expand the spectrum of antimicrobial activity over that of the traditional,
regulatory-approved substances. Most of the traditional food antimicrobials have limited application
due to pH or food component interactions. Interest in natural antimicrobials is also driven by the
fact that international regulatory agencies are generally very strict as to requirements for toxico-
logical evaluation of novel direct food antimicrobials. An argument often used to justify natural
antimicrobials is that they will produce “green” labels (i.e., with few or no “synthetic” additives
in the ingredient list). However, this justification may lead consumers to the mistaken belief that
antimicrobial food additives currently in use are potentially toxic and should be avoided. In short,
natural antimicrobials have excellent potential but likely will not produce miracles. This has not
stopped researchers from continuing to look for the “perfect” food antimicrobial. However, a single
compound that is effective against all microorganisms in all storage situations and in all foods
likely does not exist. More research is needed on the effectiveness of antimicrobial combinations
and antimicrobials in combination with physical methods (e.g., hurdle technology) that are effective
against different groups of microorganisms. Combinations could well be the ideal antimicrobial
for which everyone is searching.
It has been approximately 12 years since the second edition of Antimicrobials in Foods was
published. In that time, many changes have taken place in the field of food microbiology and the
research area of food antimicrobials. At the time of the second edition, major outbreaks of Escher-
ichia coli O157:H7 and Listeria monocytogenes had not occurred, consumer and regulatory
demands for improved food safety were only beginning, and use of naturally occurring antimicro-
bials was in its infancy. At the time of the second edition, lysozyme, lactoferrin, ozone, and several
other compounds were not approved for use in or on foods in the United States. Since the time of
the second edition, a great deal of progress has been made on determining the spectrum of action,
environmental effects on activity, and mechanisms of action of a number of naturally occurring
antimicrobials.
Because of the many changes since the second edition of Antimicrobials in Foods, considerable
revisions have been made for this third edition. As previously, one thing that has not changed is
the excellent international reputations of the authors of each chapter. Some of the authors are new,
DK2313_C000.fm Page 12 Friday, April 1, 2005 10:09 AM
but, as in the second edition, all are well-recognized experts on their topics. The format for each
chapter varies somewhat depending on the areas each author wishes to emphasize. In general,
chapters on specific antimicrobials include information on spectrum of activity, application to foods,
mechanisms or potential mechanisms of action, regulations, toxicological aspects, and assay in
foods. In the third edition, five new chapters have been added. New chapters on specific antimicro-
bials include those on lysozymes, naturally occurring antimicrobials from animal sources, and
naturally occurring antimicrobials from plant sources. In addition, chapters have been added on
hurdle technology and mechanisms of action, resistance, and stress adaptation. All existing chapters
were extensively revised to reflect research that has taken place since 1993, the publication date
of the second edition. The editors would like to thank the chapter authors for their dedication and
hard work in producing their excellent works. We sincerely hope that these discussions will continue
to be useful for industrial, academic, and regulatory research scientists, technical advisors, industry
consultants, regulators, consumers, and consumer advocates regarding the potential value of anti-
microbials in the food supply.

P. Michael Davidson is a professor of food microbiology at the University of Tennessee, Knoxville.
Serving on the editorial board of several journals and as scientific coeditor of the Journal of Food
Protection, Dr. Davidson is the author or coauthor of more than 150 journal articles, book chapters,
and abstracts. He is a Fellow of the American Academy of Microbiology and the Institute of Food
Technologists (IFT) and is a member of the American Society for Microbiology (ASM), the Society
for Applied Microbiology, and the International Association of Food Protection. He served as chair
of the food microbiology divisions of both the ASM and IFT. Dr. Davidson received the B.S. degree
(1972) from the University of Idaho, Moscow, the M.S. degree (1977) from the University of
Minnesota, Minneapolis-St. Paul, and the Ph.D. degree (1979) in food science and technology from
Washington State University, Pullman.
John N. Sofos, Ph.D., is professor of food microbiology at Colorado State University, Fort Collins.
Serving on the U.S. National Advisory Committee on Microbiological Criteria for Foods and as a
scientific coeditor of the Journal of Food Protection, Dr. Sofos has authored or coauthored more
than 220 referred papers, book chapters, books, and more than 250 abstracts. He is a Fellow of the
American Academy of Microbiology and of the Institute of Food Technologists. He also has received
research awards from the American Meat Science Association and the American Society of Animal
Science, the Educator Award from the International Association for Food Protection, and the United
States Department of Agriculture Secretary’s Honor Award for Superior Service for studies on
bacterial pathogen control. Dr. Sofos received a B.S. degree from the Aristotle University of
Thessaloniki, Greece, and M.S. and Ph.D. degrees from the University of Minnesota.
Alfred Larry Branen is associate vice president for research and outreach and associate director
of the Center for Advanced Microelectronic and Biomolecular Research (CAMBR) at the University
of Idaho Research Park in Post Falls. Formerly dean of the College of Agricultural and Life Sciences
at the University of Idaho and head of the Department of Food Science and Technology at the
University of Nebraska, Lincoln, Dr. Branen is the author or coauthor of more than 50 professional
papers and coeditor, with P. Michael Davidson, John Thorngate, and Seppo Salminen, of Food
