OR HOLDING HUMAN FOOD--Table of Contents
 
                      Subpart A--General Provisions
 
Sec. 110.3  Definitions.
 
 
    The definitions and interpretations of terms in section 201 of the 
Federal Food, Drug, and Cosmetic Act (the act) are applicable to such 
terms when used in this part. The following definitions shall also 
apply:
    (a) Acid foods or acidified foods means foods that have an 
equilibrium pH of 4.6 or below.
    (b) Adequate means that which is needed to accomplish the intended 
purpose in keeping with good public health practice.
    (c) Batter means a semifluid substance, usually composed of flour 
and other ingredients, into which principal components of food are 
dipped or with which they are coated, or which may be used directly to 
form bakery foods.
    (d) Blanching, except for tree nuts and peanuts, means a 
prepackaging heat treatment of foodstuffs for a sufficient time and at a 
sufficient temperature to partially or completely inactivate the 
naturally occurring enzymes and to effect other physical or biochemical 
changes in the food.
    (e) Critical control point means a point in a food process where 
there is a high probability that improper control may cause, allow, or 
contribute to a hazard or to filth in the final food or decomposition of 
the final food.
    (f) Food means food as defined in section 201(f) of the act and 
includes raw materials and ingredients.
    (g) Food-contact surfaces are those surfaces that contact human food 
and those surfaces from which drainage onto the food or onto surfaces 
that contact the food ordinarily occurs during the normal course of 
operations. ``Food-contact surfaces'' includes utensils and food-contact 
surfaces of equipment.
    (h) Lot means the food produced during a period of time indicated by 
a specific code.
    (i) Microorganisms means yeasts, molds, bacteria, and viruses and 
includes, but is not limited to, species having public health 
significance. The term ``undesirable microorganisms'' includes those 
microorganisms that are of public health significance, that subject food 
to decomposition, that indicate that food is contaminated with filth, or 
that otherwise may cause food to be adulterated within the meaning of 
the act. Occasionally in these regulations, FDA used the adjective 
``microbial'' instead of using an adjectival phrase containing the word 
microorganism.
    (j) Pest refers to any objectionable animals or insects including, 
but not limited to, birds, rodents, flies, and larvae.
 
[[Page 216]]
 
    (k) Plant means the building or facility or parts thereof, used for 
or in connection with the manufacturing, packaging, labeling, or holding 
of human food.
    (l) Quality control operation means a planned and systematic 
procedure for taking all actions necessary to prevent food from being 
adulterated within the meaning of the act.
    (m) Rework means clean, unadulterated food that has been removed 
from processing for reasons other than insanitary conditions or that has 
been successfully reconditioned by reprocessing and that is suitable for 
use as food.
    (n) Safe-moisture level is a level of moisture low enough to prevent 
the growth of undesirable microorganisms in the finished product under 
the intended conditions of manufacturing, storage, and distribution. The 
maximum safe moisture level for a food is based on its water activity 
(aw). An aw will be considered safe for a food if 
adequate data are available that demonstrate that the food at or below 
the given aw will not support the growth of undesirable 
microorganisms.
    (o) Sanitize means to adequately treat food-contact surfaces by a 
process that is effective in destroying vegetative cells of 
microorganisms of public health significance, and in substantially 
reducing numbers of other undesirable microorganisms, but without 
adversely affecting the product or its safety for the consumer.
    (p) Shall is used to state mandatory requirements.
    (q) Should is used to state recommended or advisory procedures or 
identify recommended equipment.
    (r) Water activity (aw) is a measure of the free moisture 
in a food and is the quotient of the water vapor pressure of the 
substance divided by the vapor pressure of pure water at the same 
temperature.

Sec. 110.10  Personnel.
 
    The plant management shall take all reasonable measures and 
precautions to ensure the following:
    (a) Disease control. Any person who, by medical examination or 
supervisory observation, is shown to have, or appears to have, an 
illness, open lesion, including boils, sores, or infected wounds, or any 
other abnormal source of microbial contamination by which there is a 
reasonable possibility of food, food-contact surfaces, or food-packaging 
materials becoming contaminated, shall be excluded from any operations 
which may be expected to result in such contamination until the 
condition is corrected. Personnel shall be instructed to report such 
health conditions to their supervisors.
    (b) Cleanliness. All persons working in direct contact with food, 
food-contact surfaces, and food-packaging materials shall conform to 
hygienic practices while on duty to the extent necessary to protect 
against contamination of food. The methods for maintaining cleanliness 
include, but are not limited to:
    (1) Wearing outer garments suitable to the operation in a manner 
that protects against the contamination of food, food-contact surfaces, 
or food-packaging materials.
    (2) Maintaining adequate personal cleanliness.
    (3) Washing hands thoroughly (and sanitizing if necessary to protect 
against contamination with undesirable microorganisms) in an adequate 
hand-washing facility before starting work, after each absence from the 
work
 
 
[[Page 217]]
 
station, and at any other time when the hands may have become soiled or 
contaminated.
    (4) Removing all unsecured jewelry and other objects that might fall 
into food, equipment, or containers, and removing hand jewelry that 
cannot be adequately sanitized during periods in which food is 
manipulated by hand. If such hand jewelry cannot be removed, it may be 
covered by material which can be maintained in an intact, clean, and 
sanitary condition and which effectively protects against the 
contamination by these objects of the food, food-contact surfaces, or 
food-packaging materials.
    (5) Maintaining gloves, if they are used in food handling, in an 
intact, clean, and sanitary condition. The gloves should be of an 
impermeable material.
    (6) Wearing, where appropriate, in an effective manner, hair nets, 
headbands, caps, beard covers, or other effective hair restraints.
    (7) Storing clothing or other personal belongings in areas other 
than where food is exposed or where equipment or utensils are washed.
    (8) Confining the following to areas other than where food may be 
exposed or where equipment or utensils are washed: eating food, chewing 
gum, drinking beverages, or using tobacco.
    (9) Taking any other necessary precautions to protect against 
contamination of food, food-contact surfaces, or food-packaging 
materials with microorganisms or foreign substances including, but not 
limited to, perspiration, hair, cosmetics, tobacco, chemicals, and

    (c) Education and training. Personnel responsible for identifying 
sanitation failures or food contamination should have a background of 
education or experience, or a combination thereof, to provide a level of 
competency necessary for production of clean and safe food. Food 
handlers and supervisors should receive appropriate training in proper 
food handling techniques and food-protection principles and should be 
informed of the danger of poor personal hygiene and insanitary 
practices.
    (d) Supervision. Responsibility for assuring compliance by all 
personnel with all requirements of this part shall be clearly assigned 
to competent supervisory personnel.

PART 110--CURRENT GOOD MANUFACTURING PRACTICE IN MANUFACTURING, PACKING, 
OR HOLDING HUMAN FOOD--Table of Contents
 
               Subpart E--Production and Process Controls
 
Sec. 110.80  Processes and controls.
 
 
    All operations in the receiving, inspecting, transporting, 
segregating, preparing, manufacturing, packaging, and storing of food 
shall be conducted in accordance with adequate sanitation principles. 
Appropriate quality control operations shall be employed to ensure that 
food is suitable for human consumption and that food-packaging materials 
are safe and suitable. Overall sanitation of the plant shall be under 
the supervision of one or more competent individuals assigned 
responsibility for this function. All reasonable precautions shall be 
taken to ensure that production procedures do not contribute 
contamination from any source. Chemical, microbial, or extraneous-
material testing procedures shall be used where necessary to identify 
sanitation failures or possible food contamination. All food that has 
become contaminated to the extent that it is adulterated within the 
meaning of the act shall be rejected, or if permissible, treated or 
processed to eliminate the contamination.
    (a) Raw materials and other ingredients. (1) Raw materials and other 
ingredients shall be inspected and segregated or otherwise handled as 
necessary to ascertain that they are clean and suitable for processing 
into food and shall be stored under conditions that will protect against 
contamination and minimize deterioration. Raw materials shall be washed 
or cleaned as necessary to remove soil or other contamination. Water 
used for washing, rinsing, or conveying food shall be safe and of 
adequate sanitary quality. Water may be reused for washing, rinsing, or 
conveying food if it does not increase the level of contamination of the 
food. Containers and carriers of raw materials should be inspected on 
receipt to ensure that their condition has not contributed to the 
contamination or deterioration of food.
    (2) Raw materials and other ingredients shall either not contain 
levels of microorganisms that may produce food poisoning or other 
disease in humans, or they shall be pasteurized or otherwise treated 
during manufacturing operations so that they no longer contain levels 
that would cause the product to be adulterated within the meaning of the 
act. Compliance with this requirement may be verified by any effective 
means, including purchasing raw materials and other ingredients under a 
supplier's guarantee or certification.
    (3) Raw materials and other ingredients susceptible to contamination 
with aflatoxin or other natural toxins shall comply with current Food 
and Drug Administration regulations and action levels for poisonous or 
deleterious substances before these materials or ingredients are 
incorporated into finished food. Compliance with this requirement may be 
accomplished by purchasing raw materials and other ingredients under a 
supplier's guarantee or
 
[[Page 222]]
 
certification, or may be verified by analyzing these materials and 
ingredients for aflatoxins and other natural toxins.
    (4) Raw materials, other ingredients, and rework susceptible to 
contamination with pests, undesirable microorganisms, or extraneous 
material shall comply with applicable Food and Drug Administration 
regulations and defect action levels for natural or unavoidable defects 
if a manufacturer wishes to use the materials in manufacturing food. 
Compliance with this requirement may be verified by any effective means, 
including purchasing the materials under a supplier's guarantee or 
certification, or examination of these materials for contamination.
    (5) Raw materials, other ingredients, and rework shall be held in 
bulk, or in containers designed and constructed so as to protect against 
contamination and shall be held at such temperature and relative 
humidity and in such a manner as to prevent the food from becoming 
adulterated within the meaning of the act. Material scheduled for rework 
shall be identified as such.
    (6) Frozen raw materials and other ingredients shall be kept frozen. 
If thawing is required prior to use, it shall be done in a manner that 
prevents the raw materials and other ingredients from becoming 
adulterated within the meaning of the act.
    (7) Liquid or dry raw materials and other ingredients received and 
stored in bulk form shall be held in a manner that protects against 
contamination.
    (b) Manufacturing operations. (1) Equipment and utensils and 
finished food containers shall be maintained in an acceptable condition 
through appropriate cleaning and sanitizing, as necessary. Insofar as 
necessary, equipment shall be taken apart for thorough cleaning.
    (2) All food manufacturing, including packaging and storage, shall 
be conducted under such conditions and controls as are necessary to 
minimize the potential for the growth of microorganisms, or for the 
contamination of food. One way to comply with this requirement is 
careful monitoring of physical factors such as time, temperature, 
humidity, aw, pH, pressure, flow rate, and manufacturing 
operations such as freezing, dehydration, heat processing, 
acidification, and refrigeration to ensure that mechanical breakdowns, 
time delays, temperature fluctuations, and other factors do not 
contribute to the decomposition or contamination of food.
    (3) Food that can support the rapid growth of undesirable 
microorganisms, particularly those of public health significance, shall 
be held in a manner that prevents the food from becoming adulterated 
within the meaning of the act. Compliance with this requirement may be 
accomplished by any effective means, including:
    (i) Maintaining refrigerated foods at 45  deg.F (7.2  deg.C) or 
below as appropriate for the particular food involved.
    (ii) Maintaining frozen foods in a frozen state.
    (iii) Maintaining hot foods at 140  deg.F (60  deg.C) or above.
    (iv) Heat treating acid or acidified foods to destroy mesophilic 
microorganisms when those foods are to be held in hermetically sealed 
containers at ambient temperatures.
    (4) Measures such as sterilizing, irradiating, pasteurizing, 
freezing, refrigerating, controlling pH or controlling aw 
that are taken to destroy or prevent the growth of undesirable 
microorganisms, particularly those of public health significance, shall 
be adequate under the conditions of manufacture, handling, and 
distribution to prevent food from being adulterated within the meaning 
of the act.
    (5) Work-in-process shall be handled in a manner that protects 
against contamination.
    (6) Effective measures shall be taken to protect finished food from 
contamination by raw materials, other ingredients, or refuse. When raw 
materials, other ingredients, or refuse are unprotected, they shall not 
be handled simultaneously in a receiving, loading, or shipping area if 
that handling could result in contaminated food. Food transported by 
conveyor shall be protected against contamination as necessary.
    (7) Equipment, containers, and utensils used to convey, hold, or 
store raw materials, work-in-process, rework, or food shall be 
constructed, handled, and maintained during manufacturing or
 
[[Page 223]]
 
storage in a manner that protects against contamination.
    (8) Effective measures shall be taken to protect against the 
inclusion of metal or other extraneous material in food. Compliance with 
this requirement may be accomplished by using sieves, traps, magnets, 
electronic metal detectors, or other suitable effective means.
    (9) Food, raw materials, and other ingredients that are adulterated 
within the meaning of the act shall be disposed of in a manner that 
protects against the contamination of other food. If the adulterated 
food is capable of being reconditioned, it shall be reconditioned using 
a method that has been proven to be effective or it shall be reexamined 
and found not to be adulterated within the meaning of the act before 
being incorporated into other food.
    (10) Mechanical manufacturing steps such as washing, peeling, 
trimming, cutting, sorting and inspecting, mashing, dewatering, cooling, 
shredding, extruding, drying, whipping, defatting, and forming shall be 
performed so as to protect food against contamination. Compliance with 
this requirement may be accomplished by providing adequate physical 
protection of food from contaminants that may drip, drain, or be drawn 
into the food. Protection may be provided by adequate cleaning and 
sanitizing of all food-contact surfaces, and by using time and 
temperature controls at and between each manufacturing step.
    (11) Heat blanching, when required in the preparation of food, 
should be effected by heating the food to the required temperature, 
holding it at this temperature for the required time, and then either 
rapidly cooling the food or passing it to subsequent manufacturing 
without delay. Thermophilic growth and contamination in blanchers should 
be minimized by the use of adequate operating temperatures and by 
periodic cleaning. Where the blanched food is washed prior to filling, 
water used shall be safe and of adequate sanitary quality.
    (12) Batters, breading, sauces, gravies, dressings, and other 
similar preparations shall be treated or maintained in such a manner 
that they are protected against contamination. Compliance with this 
requirement may be accomplished by any effective means, including one or 
more of the following:
    (i) Using ingredients free of contamination.
    (ii) Employing adequate heat processes where applicable.
    (iii) Using adequate time and temperature controls.
    (iv) Providing adequate physical protection of components from 
contaminants that may drip, drain, or be drawn into them.
    (v) Cooling to an adequate temperature during manufacturing.
    (vi) Disposing of batters at appropriate intervals to protect 
against the growth of microorganisms.
    (13) Filling, assembling, packaging, and other operations shall be 
performed in such a way that the food is protected against 
contamination. Compliance with this requirement may be accomplished by 
any effective means, including:
    (i) Use of a quality control operation in which the critical control 
points are identified and controlled during manufacturing.
    (ii) Adequate cleaning and sanitizing of all food-contact surfaces 
and food containers.
    (iii) Using materials for food containers and food- packaging 
materials that are safe and suitable, as defined in Sec. 130.3(d) of 
this chapter.
    (iv) Providing physical protection from contamination, particularly 
airborne contamination.
    (v) Using sanitary handling procedures.
    (14) Food such as, but not limited to, dry mixes, nuts, intermediate 
moisture food, and dehydrated food, that relies on the control of 
aw for preventing the growth of undesirable microorganisms 
shall be processed to and maintained at a safe moisture level. 
Compliance with this requirement may be accomplished by any effective 
means, including employment of one or more of the following practices:
    (i) Monitoring the aw of food.
    (ii) Controlling the soluble solids-water ratio in finished food.
    (iii) Protecting finished food from moisture pickup, by use of a 
moisture barrier or by other means, so that the
 
[[Page 224]]
 
aw of the food does not increase to an unsafe level.
    (15) Food such as, but not limited to, acid and acidified food, that 
relies principally on the control of pH for preventing the growth of 
undesirable microorganisms shall be monitored and maintained at a pH of 
4.6 or below. Compliance with this requirement may be accomplished by 
any effective means, including employment of one or more of the 
following practices:
    (i) Monitoring the pH of raw materials, food in process, and 
finished food.
    (ii) Controlling the amount of acid or acidified food added to low-
acid food.
    (16) When ice is used in contact with food, it shall be made from 
water that is safe and of adequate sanitary quality, and shall be used 
only if it has been manufactured in accordance with current good 
manufacturing practice as outlined in this part.
    (17) Food-manufacturing areas and equipment used for manufacturing 
human food should not be used to manufacture nonhuman food-grade animal 
feed or inedible products, unless there is no reasonable possibility for 
the contamination of the human food.

                     Subpart G--Defect Action Levels
 
Sec. 110.110  Natural or unavoidable defects in food for human use that present no health hazard.
 
 
    (a) Some foods, even when produced under current good manufacturing 
practice, contain natural or unavoidable defects that at low levels are 
not hazardous to health. The Food and Drug Administration establishes 
maximum levels for these defects in foods produced under current good 
manufacturing practice and uses these levels in deciding whether to 
recommend regulatory action.
    (b) Defect action levels are established for foods whenever it is 
necessary and feasible to do so. These levels are subject to change upon 
the development of new technology or the availability of new 
information.
    (c) Compliance with defect action levels does not excuse violation 
of the requirement in section 402(a)(4) of the act that food not be 
prepared, packed, or held under unsanitary conditions or the 
requirements in this part that food manufacturers, distributors, and 
holders shall observe current good manufacturing practice. Evidence 
indicating that such a violation exists causes the food to be 
adulterated within the meaning of the act, even though the amounts of 
natural or unavoidable defects are lower than the currently established 
defect action levels. The manufacturer, distributor, and holder of food 
shall at all times utilize quality control operations that reduce 
natural or unavoidable defects to the lowest level currently feasible.
    (d) The mixing of a food containing defects above the current defect 
action level with another lot of food is not permitted and renders the 
final food adulterated within the meaning of the act, regardless of the 
defect level of the final food.
    (e) A compilation of the current defect action levels for natural or 
unavoidable defects in food for human use that present no health hazard 
may be obtained upon request from the Center for Food Safety and Applied 
Nutrition (HFS-565), Food and Drug Administration, 5100 Paint Branch 
Pkwy., College Park, MD 20740.
