Three Pillars of Successful Food Safety Management

Culture Science Systems

Culture

Culture

• Food safety culture

– Behavior-based

– Ethos

Creating a Food Safety Culture

1. Expectations

2. Education

3. Communication of food safety messages frequently

4. Goals and measurements

5. Consequences and rewards for behaviors

Food Safety Culture

• Covers the intangibles and grey areas

• Foundational for food safety management

The First Step in HACCP

• Gain management support

• “The criticality of gaining management support for HACCP programs cannot be over emphasized. Without a long term commitment, the time and effort required to develop and implement such a program cannot be sustained, particularly when decisions related to process deviations require actions that may negatively impact productivity or profitability.”

– R.L. Buchanan. 2012. Hazard Analysis and Critical Control Point System: Use in Managing Microbiological Food Safety Risks, Chap. 46 In Doyle, M.P. and R.L. Buchanan, eds. “Food Microbiology: Fundamentals and Frontiers, 4th ed.” ASM Press. Washington DC.

Attributes of Food Safety Culture

• Top-down commitment

• Autonomy of the chief food safety executive

– Final Macro decisions

• Employee contribution

– Micro decisions

– Ownership/empowerment

Food Safety Culture Covers the Intangibles and “Grey Areas”

• You cannot do everything

– Need cooperation from personnel in operations, engineering, sales, marketing, etc.

• You cannot be everywhere all the time

– Worker training (education)

Food Safety Culture

• Old way: penalize plants for positive pathogen test results in their environment.

• New way:

– Listeria hunters – reward plants for proactively searching out niches and destroying Listeria

in the production environment

• Appendix B: Compliance Guidelines for Cooling Heat-Treated Meat and Poultry Products (Stabilization) – Clostridium botulinum and C. perfringens

• Performance Standard is less than 1-log increase in C. perfringens– Safe Harbor for Uncured

• 120ºF to 55ºF within 6 h, then down to 40°F• 130ºF to 80ºF in 5 h 80ºF to 45ºF in 10 hours (15 hours total cooling

time)

– Safe Harbor for Cured• 130ºF to 80ºF within 1.5 h, 80ºF to 40ºF within 5 hours (6.5 hours total

cooling time)or

– Validated “customized process” that prevents a 1 log increase in C. perfringens and C. botulinum

Internal temperatures of the various weight ranges of ribeye select (rare) were monitored during chilling with 7 calibrated probes. Probes were placed in the geometric center of each ribeye. USDA guidelines for roast beef stabilization are cooling from 120°F to 55°F in 6 hours or less.

Science

• Without science, you can spend a lot of effort on things that will impart no substantive reduction of risk but will…

– Provide a false sense of security

– Cost money

– Keep you busy

– Make you look good

Finished Product Testing

• Listeria monocytogenes

sampling of dry sausage

• “severe direct” health hazard

• Conditions of handling the food would reduce the degree of concern

• Case 13 sampling: 2-class, n = 15, c = 0

International Commission on Microbiological Specifications for Foods, 1986

Statistically-Based Sampling

• If 10% of lot was the contaminated, and you test 15 samples:– 70% chance you would

detect the contamination

• If 0.1% contaminated– 10% chance you would

detect the contaminant

– 90% chance that contamination slips through

– You would have to test 50 units to reach 95% confidence

Cost of Product Testing for Pathogens (Hold & Test)

• Overnight shipping samples R$ 133

• R$30 per pathogen test x 15 R$ 450

• Product hold time for 48h R$ 6,130

R$ 6,713

320 lots of production/year R$ 2,148,160

Why Systems?

• Change Management– Workflow

• Gatekeepers – Checks and Balances

• Consensus– Standardized

specifications

– Codes of practice

– Qualification of vendors

– Qualification as a vendor

Three Key Systems

• HACCP

– Risk management system

• Auditing

– Governmental (USDA, FDA)

– Third-Party (GFSI)

– Customer-Specific

• Worker training

Hazard Analysis Critical Control Point (HACCP)

• First systematic way to manage risk in food production

– U.S. Army Natick Laboratories and the National Aeronautics and Space Administration (NASA)

– Pillsbury Company (contractor)

• Failure Mode and Effect Analysis (FMEA)

• Haz-Ops

Seven Principles of HACCP

1. Conduct a hazard analysis.

2. Determine the critical control points (CCPs).

3. Establish critical limits (CLs).

4. Establish monitoring procedures.

5. Establish corrective actions.

6. Establish verification procedures.

7. Establish record-keeping and documentation procedures.

HACCP – Then and Now

• Initially, many CCPs

• Currently, as few CCPs as possible

– Prerequisite programs

– CPs

“HACCP Is Dead”

• “Hazard analysis is qualitative, whereas risk assessment is now used to quantify risk. However, the public wants and expects a risk-free food supply, so no level of risk is ultimately seen as acceptable..”

- Dean O. Cliver, Ph.D. (late), Emeritus Member of IFT, Professor Emeritus of Food Safety, University of California, Davis,

Food Technology March 2010, Volume 64, No.3

“HACCP Is Dead”

• “Diluting the power of the CCP by saying that it may merely reduce risk to an acceptable level (not eliminate the hazard) has degraded HACCP to a fashionable, hollow acronym.”

- Dean O. Cliver, Ph.D. (late), Emeritus Member of IFT, Professor Emeritus of Food Safety, University of California, Davis,

Food Technology March 2010, Volume 64, No.3

What’s Next for HACCP?

• SPC

• System thinking

• eHACCP

– WTO, FAO, CDC, FDA

• GFSI Recognized Schemes:

– BRC, CanadaGAP, FSSC 22000, Global Aquaculture, GLOBAL G.A.P., GRMS, IFS, PrimusGFS, SQF

Audits

• USDA-FSIS

• FDA

• CODEX Alimentarius

• GFSI (1 of 9 schemes)
