Food safety
refers to routines in the preparation, handling, and storage of food meant to
prevent foodborne illness and injury. From farm to factory to fork, food
products may encounter any number of health hazards during their journey
through the supply chain. Safe food handling practices and procedures are thus
implemented at every stage of the food production life cycle in order to curb
these risks and prevent harm to consumers.
As a scientific
discipline, food safety draws from a wide range of academic fields, including
chemistry, microbiology, and engineering. These diverse schools of thought
converge to ensure that food processing safety is carried out wherever food
products are sourced, manufactured, prepared, stored, or sold. In this sense,
food safety is a systemic approach to hygiene and accountability that concerns
every aspect of the global food industry.
The following
article defines food safety in manufacturing and explains the importance of
food safety for the global food chain. Following a brief overview of the
different regulatory bodies tasked with evaluating food safety around the
world, the article outlines the key principles of effective food safety
regulation, the history of food safety, and the consequences of unsafe food
handling practices and procedures for companies and consumers.
Food safety
regulations in a globalized world
Food products
are among the most-traded commodities in the world. As markets become
increasingly globalized with each passing year, and as the world’s population
continues to grow, the global food supply chain will only continue to increase
in scale and complexity. Precisely because of these megatrends influencing the
mass production and distribution of food, food safety compliance has never been
more important.
Every country
has different regulatory bodies that preside over the definition and
enforcement of domestic food safety standards. In order to sell or manufacture
food products in any given country, domestic and international businesses alike
are subject to the food safety legislation and enforcement measures of that
nation. In the European Union, for example, food safety legislation is detailed
in Regulation (EC) 852. In the United States, the Food Safety Modernization Act
outlines the legal requirements for food safety.
Around the
world, the majority of laws about food safety are based on two concepts: HACCP
and GMP:
HACCP –
Hazard Analysis and Critical Control Points is a systemic, risk-based approach
to preventing the biological, chemical, and physical contamination of food in
production, packaging, and distribution environments. The HACCP concept is
designed to counter health hazards by identifying potential food safety
problems before they happen, rather than inspect food products for hazards
after the fact. The HACCP concept entails controlling for contaminants at a
number of key junctures in the food production process and strict adherence to
hygiene practices throughout.
GMP –
Good Manufacturing Practices are internationally recognized quality assurance
guidelines for the production of food, beverages, cosmetics, pharmaceuticals,
dietary supplements, and medical devices. These guidelines lay out the
protocols which manufacturers must implement to assure that their products are
consistently high-quality from batch to batch and safe for human use, including
mandatory product inspection at critical control points.
There are also
several privately-owned international organizations that provide comprehensive
guidelines for auditing food manufacturers on the basis of food safety and
hygiene. These international standards facilitate the global food trade by
helping food industry players from different countries to ensure that food
quality and safety standards are met in a way that transcends borders. In
addition to complying with the food safety laws of the countries in which they
are active, global market leaders in the food industry often pursue
certification with a number of private food regulators. They may furthermore
demand that the upstream and downstream suppliers they work with provide proof
of the same certifications.
Internationally
recognized food safety organizations and certification programs include:
IFS Food 6.1
– The IFS Food Standard is part of the Global Food Safety Initiative and is
an international standard for performing audits of food manufacturing
processes. Their compliance audits concern both the factory floor and
administrative duties, with regulations on topics ranging from the installation
of food defense and inspection equipment to thorough bookkeeping.
BRCGS –
The British Retail Consortium Global Standards (formerly BRC) are a set of
international consumer protection certifications that provide safety criteria
for global food retailers, food manufacturers, packaging manufacturers, and
food service organizations. Their certification for food manufacturers includes
an assessment of the equipment used to detect and remove physical
contaminants.
SQF –
The Safe Quality Food Institute provides detailed safety programs tailored to
the specific concerns of different food industry players. The various SQF codes
are segmented to address the unique conditions of each stage of the food
production life cycle, from agriculture to packaging, from manufacturing to
retail. Each SQF program is internationally recognized.
Each of these
private food safety organizations have built their certification programs
around ISO 22000, an international norm for food safety management systems:
ISO 22000 –
The International Organization for Standardization details a proactive
management plan for food safety relevant for any organization along the food
supply chain. ISO 22000 includes an interactive communication strategy between
upstream and downstream industry players and a comprehensive system for
management. Furthermore, the norm encompasses a model for how to implement a
customized HACCP concept depending on the industry, product, and facilities.
For instance, should a risk of metal contamination be identified, ISO 22000 may
recommend the installation of a metal detector with a rejection mechanism to
manage the hazard.
Who is
responsible for enforcing food safety standards?
While the
international regulatory bodies listed above provide guidance, certification,
and auditing services for global food manufacturers, they are not responsible
for the active enforcement of food safety laws. Every nation defines and
establishes its own laws and enforcement practices for food safety regulation,
and these regulations may vary from country to country, and domestically from
region to region. Bringing a food product to a foreign market requires compliance
with the food safety and consumer protection laws of that nation and its
regional governmental authorities.
Generally
speaking, international food safety standards are designed to facilitate
compliance with food safety laws in major markets, simplifying the process of
receiving approval from foreign governmental regulators.
The history
of food safety
Foodborne
illness has threatened human health since the dawn of time. In fact, many food
preparation methods we still use today, such as cooking, canning, smoking, and
fermentation, can be understood as primitive food safety measures, developed as
a means of keeping people from getting sick.
Today, we
benefit from centuries of scientific and technological progress that have made
an abundance of safe food and drink products something that many of us take for
granted. But the concept of food safety as we know it today, and the rigor with
which it is enforced, is a relatively new development in human history that is
intimately tied to changes in the way we live and eat.
In 1905,
American author Upton Sinclair published his novel The Jungle, which featured
horrific depictions of Chicago’s meatpacking industry. The ensuing public
outrage led the U.S. government to pass the Meat Inspection Act the following
year, establishing the first sanitary standards for slaughtering and
butchering. This law marked the first time that food processing facilities were
subject to regular audits and inspections by governmental authorities and some
of the very first laws for food safety in manufacturing.
Across Europe
and North America, the industrial revolution ushered in the establishment of
many regulatory bodies and foundational laws concerning food safety and
inspection. As food production became increasingly mechanized and profit
incentives climbed, laws were passed to prevent the intentional sale of food
products that were misbranded, contaminated, or otherwise tampered with. It was
during this era that ingredients and additives became subject to regulation.
In the decades
following World War II, electric refrigerators entered middle class homes
across Europe and North America, changing the way that everyday people
purchased and stored food. The era of home refrigeration sparked the rapid
expansion of industrial food production, as well as a growing need for stricter
food regulations. It was in this changing food landscape that Mars Incorporated
became the first major food manufacturer to install metal detectors in their
facilities in 1947.
The shift from
reactive to proactive food safety principles began when HACCP was born in 1959.
Recognizing that testing finished products was not an effective means of
ensuring food quality and safety, scientists at NASA collaborated with the
Pillsbury Company to create a risk-based system that identified “critical
failure areas” in production that posed health risks. With Pillsbury leading
the way, this system of hazard analysis and control was adopted by a number of
leading food manufacturers in the United States.
By the
mid-1980s, scientists around the world agreed that the proactive nature of
HACCP provided a more effective means of controlling for food safety hazards
than traditional inspection methods. The following decades saw the
establishment of international regulatory bodies and third-party audit firms
designed to implement and enforce preventative compliance in an increasingly
globalized food industry. It is upon this groundwork that modern food safety
regulations and practices are built.
The seven
principles of a safe food supply chain
While HACCP
lays out the steps necessary to proactively ensure food quality safety in
individual food production environments, a healthy supply chain also demands
action on a collective level. The European Union identifies seven overarching
food safety principles necessary for the entire food supply chain to operate
for the public good.
Corporate responsibility – Every company
involved in the food supply chain is required to do their due diligence to
ensure the quality and safety of a food product within the bounds of their
responsibility. This includes implementing in-house controls according to
HACCP. In addition, corporations assume liability for any damages their
products may cause.
Traceability
– All food business operators in the EU are responsible for documenting
where their materials are sourced and where they are sent. This documentation
helps regulatory bodies quickly identify the source of contamination should a
recall become necessary.
Official
food controls – Governmental authorities within the federal states are
responsible for enforcing EU food law requirements through risk-oriented
reviews, targeted sample collection, and regular inspections.
The
precautionary principle – Competent authorities are permitted to take
precautionary measures if they believe the effect will minimize food safety
risks. These precautionary measures will be reviewed on an ongoing basis as
scientific data becomes available.
Independent
scientific risk assessment – A governmental institution that operates
independently of political, social, and economic influences is responsible for
scientifically investigating and assessing the risks that food products may
pose to human health. In the EU, this institution is known as the European Food
Safety Authority.
Separation
of risk assessment and risk management – Due to possible conflicts of
interest, a clear distinction is made between those responsible for scientific
risk assessment and those responsible for risk management.
Transparent
risk communication – The public must be promptly informed of
imminent and potential food safety hazards. Circulating information about food
safety problems is only possible if scientists, policymakers, and food business
operators communicate transparently.
The
importance of food safety and the consequences of non-compliance
Food safety is
highly important both financially and ethically. The consequences of failing to
comply with food safety standards are manifold. In addition to being incredibly
costly for companies who must recall their products, overhaul their processes, and
manage the public relations crisis, inadequate food safety in manufacturing
carries a significant human cost.
The cost of
food recalls for companies
Failing to
implement an effective food safety protocol can lead to contaminated products
entering the food chain. Once the defective product has been discovered, food
businesses are subject to dramatic disruptions in their operations as they
manage and assume the cost for product recalls.
Food recalls
cost companies an average of $10 million USD in direct, immediately measurable
costs alone. But the long-term effect that a product recall can have on
consumer trust is perhaps even more costly. Some 21 percent of consumers say
they would never again purchase anything from manufacturer who had to recall
one of their food products.
The human
cost of unsafe food
The importance
of food safety to modern human life would be difficult to understate. Food
safety problems are a leading cause of more than 200 preventable diseases
worldwide. Each year, one in ten people will suffer from foodborne illness or
injury. An estimated 420,000 people die every year as a result of eating
contaminated food, and more than a quarter of these victims are small children.
In addition to
the immediate human cost, inadequate food safety comes with a greater ripple
effect that impedes socioeconomic progress, especially in the developing world.
The World Health Organization states that food safety, nutrition, and food
security are inextricably linked. A lack of safe food creates a “vicious cycle
of disease and malnutrition” which overburdens public health services, disrupts
social and economic progress, and detracts from the quality of life.
