The Committee on Food and Chemical Safety promotes a science-based determination of the chemical safety of foods to support the advancement of public health.

How this committee operates:

The Food and Chemical Safety committee focuses on many different issues related to the safety of the food supply.  In order to maximize output, the committee is segmented into  subcommittees, each focusing on a specific area of food and chemical safety.  Explore those subcommittees and the impact of their work below.

Scientific Sessions

Controlling foodborne pathogens Managing Risk Debate: Food Safety Perspectives Chemical & Microbial Risk Assessment Controlling foodborne pathogens

Battling Bad Bugs: Biological Approaches to Control Pathogens
Monday, July 10, 2017 from 3:30- 5:00 PM

Session Conveners: Isabel Walls, USDA NIFA, and Kendra Nightingale, Texas Tech University

Abstract:
The food industry often relies on physical and chemical interventions to control foodborne pathogens. This session is intended to discuss biological approaches to control foodborne pathogens throughout the food continuum. Topics to be covered include the use of (i) biocontrol of Listeria monocytogenes and Salmonella enterica Serovar Poona on fresh-cut apples with naturally occurring bacterial and yeast antagonists, (ii) probiotics to reduce the load of foodborne pathogens that enter the human food chain and pathogen populations on food and in food processing environments and (iii) bacteriophage to combat bacterial foodborne pathogens. This session will also include discussions on consumer perception and acceptance of these biological approaches to control foodborne pathogens.

Managing Risk

Managing Risk in a Zero Tolerance World
Tuesday, July 11, 2017 from 8:30 AM - 12:00 PM

Session Conveners: Laurie Post, Deibel Labs, Edith Wilkin, Leprino Foods Company

Abstract: It is accepted that there is risk in everything and the discipline of risk assessment focuses on minimizing risk to an acceptable level. This seems to be in conflict with the concept of zero tolerance, which is not completely codified in regulation and yet does seem to exist in actual food industry practice. Does the current interpretation of FSMA rules and regulatory application of new technologies in outbreak investigation drive the expectation of a zero-risk environment? What should risk assessment and food safety management look like in this changing landscape? How can risk be managed to allow suitable options for consumers and food manufacturers? The perception and understanding of risk necessitates a conversation between regulators, consumers, and the food industry.

Debate: Food Safety Perspectives

A Debate: Current Perspectives in Food Safety
Wednesday, July 12, 2017 from 8:30 AM to 10:00 AM

Abstract: This interactive roundtable is intended to engender lively discussion of important food safety topics. It is assumed audience participants will have a basic understanding of the unresolved issues surrounding the topics to be discussed in the symposium. The session will cover three topics: “The good, the bad, and the ugly foods: Should we encourage the consumption of “ugly” and expired foods?”; “Who’s to blame? Do consumers own a piece of food safety?”; and, “Which is the real ‘obesogen'—pizza or the pizza box?” Each topic will include a 7-minute presentation in support of (Yes, Pizza) followed by a 7-minute presentation in opposition of (No, Pizza Box) the proposed topic question. Each speaker will have 3 minutes for extemporaneous rebuttals. A 6-minute question/answer session will then follow to allow for audience participation. We will have electronic polling of the audience to allow for a Yes/No vote on each topic question prior to and following the discussion to evaluate whether people’s views have been changed by the presentations.

The traditional explanations of the cause of obesity are metabolism, genetics, increased caloric intake and insufficient energy expenditure. However, recent studies have suggested that chemicals in food contact materials, a subclass of endocrine-disrupting chemicals called the 'obesogens' may contribute to obesity by altering metabolic processes and predisposing people to gain weight. This debate explored the state of the science and contribution of different factors in obesity.

Chemical & Microbial Risk Assessment

Chemical and Microbial Risk Assessment: Similarities and Differences
Wednesday, July 12, 2017 from 10:30 AM - 12:00 PM

Convener: Doug Holt, Dr. Pepper Snapple Group

Abstract: In food safety, risk assessment is the scientific evaluation of known or potential health effects resulting from human exposure to chemicals or microorganisms. Exposure to pathogenic microorganisms is different from exposure to chemicals. Microorganisms differ from chemicals as they can grow or die and the level of exposure to microorganisms can change dramatically in a short period. The speakers in this session will discuss the similarities and differences between chemical and microbial risk assessment; risk and risk benefit analysis and will present some case studies.

Listeria monocytogenes Salmonella Listeria monocytogenes

Fate of Listeria monocytogenes in Cocoa Powder during Isothermal Inactivation
P3-16

Introduction: Listeria monocytogenes can survive in dry condition for a long period of time. Despite an increasing number of studies addressing Salmonella inactivation in low-moisture foods, there is a general lack of knowledge related to L. monocytogenes inactivation in low moisture foods during thermal processing and to the factors impacting their survival in low moisture food. Cocoa powder is an essential ingredient and widely incorporated in different desserts and drinks and thus a possible source of L. monocytogenes contamination.

Purpose: To evaluate the thermal resistance of L. monocytogenes in cocoa powder and further investigate the impact of water activity (aw) on its survival in cocoa powder.

Methods: Natural unsweetened cocoa powder (Hershey’s) was inoculated with three-strain L. monocytogenes cocktail (~9.0 log CFU/g), equilibrated to water activity (aw, 25°C) to 0.3 or 0.45, then subjected to isothermal treatments using aluminum TDT test cell containing 0.4 g of inoculated and equilibrated sample. The survivors were enumerated on TSAYE plates.

Results: Inactivation data resulted from different temperatures at both aw showed log-linear trend which was used to obtained thermal inactivation parameters. Thermal resistance of L. monocytogenes at 0.3 aw was significantly higher than that at 0.45 aw across all three temperatures. Listeria monocytogenes at 0.3 aw and 0.45 aw had D70°C of 7.44±1.17 and 4.77±0.28 min, D75°C of 3.62±0.03 and 2.84±0.09 min, and D80°C of 1.35±0.04 and 1.06±0.05 min, respectively, z-value at 0.3 aw and 0.45 aw was 13.48 and 15.31°C, respectively.

Significance: Listeria monocytogenes demonstrated much higher thermal resistance in cocoa powder compared to the high moisture foods, which is impacted by aw. Data provide valuable information for industry to validate thermal processing for control of L. monocytogenes in low moisture foods.

Salmonella

Assessment of Survival and Virulence of Salmonella in Low-moisture Foods
P3-17
Poster Presentation on Wednesday, July 12, 2017

Authors: Victor Jayeola, North Carolina State University, Raleigh, NC, Jeffrey Farber, University of Guelph, CRIFS, Department of Food Science, Guelph, Canada, Sophia Kathariou, North Carolina State University, Raleigh, NC

Introduction: Low-moisture foods (LMF) have been implicated in multiple outbreaks of salmonellosis. However, mechanisms mediating survival and virulence of Salmonella in such foods remain poorly understood

Purpose: To assess survival and virulence of Salmonella in low moisture foods.

Methods : A two-strain mixture of Salmonella enterica serotypes Typhimurium and Enteritidis was used to inoculate two model LMF, chocolate and in shell pistachios. Products (100 g) were inoculated with four ml of the Salmonella cell suspension, dried for one to three hours until aw approximated that of the uninoculated product, aliquoted into 15-ml centrifuge tubes and stored in the dark at 22°C. Salmonella populations immediately after inoculation, after drying and at 1, 4, 6, 10, 15, and 21 days were determined in triplicate on nonselective (TSA-YE) and selective (XLD) media. Virulence was tested in the insect Galleria mellonella model by injecting 10 µl of rinsate from products at one day into the last left proleg of 10 larvae. Rinsate from uninoculated products were also injected as controls. The larvae were incubated at 37°C and larval mortality was daily monitored.

Results: The population of Salmonella in the inoculated products was eight and nine log CFU/g immediately after inoculation and 7.3 and 8.0 log CFU/g after drying for chocolate and pistachios, respectively. Populations decreased to 4.5 and 7.5 log CFU/g by 21 days in chocolate and pistachios, respectively. Recovery of Salmonella from either product on TSAYE and XLD was similar. Larvae inoculated with 3.4 log CFU/ml of the cocktail had a mortality of 100% after 24 h compared to 80% of larvae inoculated with 3.9 log CFU/ml cells from chocolate and 30% for larvae inoculated with 3.7 log CFU/ml cells from pistachios. The mortality of controls was 0 and 10% for uninoculated pistachios and chocolate, respectively.

Significance: Findings show that Salmonella can survive in chocolate liquor and pistachios and that cells adapted to the LMF environment retained virulence.
