Guideline No. 4
Issued by the Food Directorate
Health Products and Food Branch
Health Canada
Revised: June 1, 2010
These guidelines have been prepared to assist manufacturers in the preparation of submissions to the Bureau of Chemical Safety (BCS), Food Directorate, Health Products and Food Branch, Health Canada, respecting the acceptability of incidental additive products intended for use in food processing plants, under the authority of the Food and Drugs Act and Regulations.
The following information is provided for guidance purposes only in order to facilitate the evaluation of incidental additives for use in food processing establishments.
While not defined under the Food and Drugs Act (FDA), incidental additives may be regarded, for administrative purposes, as those substances which are used in food processing plants and which may potentially become adventitious residues in foods. They can include products that are regulated as drugs or cosmetics under Food and Drug Regulations (FDR) but specifically exclude food additives and food packaging materials.
With the exception of certain products, which are regulated under specific regulations, such as disinfectants, cosmetics, natural health products, etc., there are no sections of the Food and Drugs Act and Regulations, which specifically require the pre-clearance of incidental additives for use in food processing plants. However, if these substances are misused, resulting in contamination of foods thereby creating a potential health risk to consumers, such an action would be considered to be in violation of Section 4(a) of the Act, which states, "No person shall sell an article of food that has in or upon it any poisonous or harmful substance"
As an example, the following products are considered to be incidental additives when they are used in food processing establishments:
Health Canada ensures that products for use in food premises are safe and effective when used according to the manufacturer instructions. Upon request, the Bureau of Chemical Safety (BCS) assesses the safety of the intended incidental additives that may come in direct contact with food in food processing establishments. However, while pre-market assessments of incidental additives products can be done on a voluntary basis by the BCS, under different use conditions, pre-market clearance may be a mandatory requirement under other legislations as presented below. Therefore, petitioners are required to contact the following governmental entities for the pre-clearance of their products, according to their respective intended application before submitting applications to the BCS. Please note that their contact information is presented in reference in Appendix I.
Petitioners wishing to use pesticides (sporicide, bactericide, virucide, fungicide, etc.) on non-food contact surfaces in food processing establishments, are also required to request an evaluation of safety (to humans, environment, etc.) and the efficacy of their product from the Pest Management Regulatory Agency (PMRA) of Health Canada before submitting their products to the Bureau of Chemical Safety.
Pesticides, sold or used in Canada, are regulated nationally under the Pest Control Products Act (PCPA). The PMRA is responsible for administering this legislation, registering pest control products, re-evaluating registered products and setting pesticide maximum residue limits (MRLs) on food. For more information about PMRA of Health Canada, you can visit the PMRA website.
Any disinfectant product (sporicide, bactericide, virucide and fungicide) intended to be used in food premises and having a therapeutic effect (preventing or controlling diseases) is considered to be a drug. For such products companies must contact the Submission and Information Policy Division of the Bureau of Policy and Coordination of the Therapeutic Products Directorate of Health Canada for Drug Identification Number (DIN) registration of their product. For more information on disinfectant drugs guidelines, you can visit the TPD website.
Any human-use antiseptic product intended to be used in food premises and having a therapeutic effect (preventing or controlling diseases by reduction of organisms on skin) is considered to be a drug under the Food and Drugs Act.
The Bureau of Chemical Safety works in partnership with the Natural Health Products Directorate (NHPD) and the Therapeutic Products Directorate (TPD) to ensure the safety and efficacy of antiseptic products intended to be used in food processing establishments. The NHPD and TPD are responsible for the mandatory pre-market assessment of human-use antiseptic products.
Hence, for products containing ingredients that meet the definition of Schedule 1 of the Natural Health Products Regulations (NHPR), sponsors are required to submit an application for a Natural Product Number (NPN) with the Natural Health Products Directorate as per Section 5 of the Natural Health Products Regulations (NHPR). Sponsors of antiseptic products for human use containing ingredients other than those that meet the definition of Schedule 1 of the NHPR are required to file an application for a Drug Identification Number (DIN) with the Therapeutic Products Directorate as per Part C, Section C.01.014 of the Food and Drug Regulations. For more information on Human-Use Antiseptic Drugs Guidance, you can visit the TPD website.
Petitioners of cosmetic products (hand cleansers, lotions, etc.) intended for use in food premises should also contact the Cosmetics Division of the Consumer Product Safety Directorate of the Healthy Environments and Consumer Safety Branch of Health Canada to provide a cosmetic notification form within 10 days of first sale of the product in Canada. These cosmetics must meet all applicable requirements under the Food and Drugs Act, and the Cosmetic Regulations to ensure that they are notified to Health Canada, properly labelled and safe to use and do not pose any health risk to consumers.
The Cosmetic Regulations of the Food and Drugs Act require that cosmetics sold in Canada must be manufactured, prepared, preserved, packed and stored under sanitary conditions. For more information on requirements for cosmetics, you can visit Health Canada's website.
Process water is potable water which is used in food processing plants and which may or may not directly contact food items and/or may be incorporated into food products (e.g., water used for general cleaning, cooking, blanching, fuming, washing foods, etc).
The chemical ingredients used in the formulation of treatment compounds for water intended for food contact application should meet the specifications set out by the Food Chemicals Codex in order to avoid or minimize unwanted impurities and this application is assessed by the Food Additive and Contaminants Section of the Bureau of Chemical Safety.
The process water so treated must meet standards set out in the latest Guidelines for Canadian Drinking Water Quality. Drinking water is primarily an area of provincial and territorial jurisdiction in Canada, but Health Canada's role is critical in all Canadian jurisdictions. Health Canada's Water Air and Climate Change Bureau works in collaboration with the provinces and territories to develop the Guidelines for Canadian Drinking Water Quality. Health Canada provides scientific expertise and national leadership on issues related to drinking water safety, whereas provincial and territorial governments are responsible for establishing regulations and requirements regarding the quality of drinking water. Provinces and territories use the guidelines as a basis to develop their own enforceable requirements for drinking water quality, either directly by reference or through their own regulatory or licensing process. For products used in the treatment of drinking water, Health Canada recommends the use of products that have been certified as meeting the appropriate health-based standard by an accredited certification body. A complete list of accredited certification bodies can be found on the website of the accreditation organization, the
Standards Council of Canada.
Petitioners wishing to use air treatments such as ozone, hydrogen peroxide or other gaseous antimicrobial agents in food processing establishments, are required to contact the Pest Management Regulatory Agency (PMRA) to inquire about the safety and efficacy of their products as antimicrobials before submitted them to the Bureau of Chemical Safety.
If the air treatment compounds are intended to be used in food holding premises where unpackaged fresh food (e.g. fruits and vegetables) or unpackaged meat are present then petitioners are required to contact the Food Additives and Contaminants Section of the Chemical Health Hazard Assessment Division, Bureau of Chemical Safety to inquire about the safety of these treatments to food.
The use of air treatment compounds in food processing establishment also requires the consideration of health risks to employees. Petitioners should contact their province where the facility is located to determine any related occupational health and safety requirements.
CFIA is responsible for food inspection and enforcement of the regulations and standards established by Health Canada and other departments. As part of its responsibilities in administering the Food and Drugs Act and Regulations, the Bureau of Chemical Safety (BCS) provides advice in the form of letters of opinion (called "no objection letters") to the Canadian Food Inspection Agency (CFIA) on matters concerning the acceptability of incidental additive products, which are proposed for use in federally registered food establishments operating under several Acts and Regulations administered by the Agency. In this aspect, Health Canada works in collaboration with the Canadian Food Inspection Agency.
Manufacturers wishing to sell products that are proposed for use in federally registered food establishments, regulated as noted above by the CFIA, must make submissions to that agency directly for formal pre-clearance allowing entry of their products into those registered plants. The Agency provides the letters of acceptance of the incidental additives products, which are intended for use in federally registered food establishments. It should be noted that such submissions are usually forwarded to the Bureau of Chemical Safety (BCS) for evaluation of the chemical safety of the products; if deemed acceptable, they are then entered in the consolidated reference listing of accepted products used in food processing establishments. This reference listing is regularly (twice a month) updated and can be found under the "
Reference Listing of Accepted Construction Materials and Non-Food Chemical Products" on the CFIA's website. For more information on CFIA's requirements, please visit the
agency's website.
Under the authority of the provisions of Section 4(a) of the Food and Drugs Act, and with the express intent of assisting food manufacturers in averting violations thereof, the Bureau of Chemical Safety (BCS) evaluates on a case-by-case basis the acceptability of various incidental additive products voluntarily submitted by manufacturers wishing to supply their products to food processors. Requests for such evaluations are called Submissions.
For products considered acceptable by the BCS, No-Objection Letters are issued, which may then be presented by the product manufacturers to prospective food processor customers. Letters expressing favourable BCS opinions are called "No Objection Letters"
A no-objection letter does not constitute an approval of the product under the Food and Drugs Act and Regulations. It is simply an opinion expressed by the BCS on the acceptability of the product, based on the information available at the time of its evaluation. Issuance of a no-objection letter does not relieve the product user (food processor) from their responsibilities relating to Section 4(a) of the Act. There is no fee attached to obtaining a no objection letter.
A no objection letter does not have an expiry date. It is considered valid as long as the composition, the intended use and the labelling content remain as described in the initial submission's application. Petitioners are responsible for notifying the BCS of any changes that may affect the validity of the no objection status. However, the BCS reserves the right to rescind the no objection status of any given product should information come to light showing that its use may potentially pose a health risk to consumers.
In order to evaluate the safety of use of incidental additive products in food plants, BCS requires that petitioners submit the following information. All such information is held in confidence and is used for evaluation purposes only. To the extent possible, these requirements are consistent with those issued by the CFIA respecting incidental additive product submissions made directly to the Agency. These are initial requirements only. Evaluation of submitted information will dictate if any clarification and/or additional information are required.
Please submit a completed Application/Checklist Form (Appendix II) to include the following:
The toxicological data submitted must be sufficient to demonstrate the safety of the incidental additive under the proposed conditions of use. In the case of inherently toxic incidental additives such as sanitizers and disinfectants, a complete set of toxicological studies would normally be required, unless the formulation in question has been previously cleared by Health Canada (i.e., PMRA). This would include acute, repeated-dose and chronic oral toxicity/ carcinogenicity studies, reproductive and development toxicity studies as well as genotoxicity studies. Special studies on metabolism and pharmacokinetics or to examine specific types of toxic effects may also be required to complete the safety assessment.
Please be advised that illegible submissions will be immediately returned to petitioners without further consideration. It is strongly urged that all submissions be typed for clarity.
Please note that, under Section 20 (1) (b) of the Access to Information Act, the information submitted above will be used in confidence for our evaluation purposes of your submission only and will not be shared with any third party unless advised otherwise by your company and/or your supplier(s) with a written notice.
A label or draft label bearing the following information:
Note: Additional labelling may be required for disinfectants and human-use antiseptic products as per the Food and Drug Regulations and the Natural Health Products Regulations.
The use of cleaning agents on food contact surfaces should at all times be followed by a thorough rinse with potable water. It is recommended that cleaners, which cannot be effectively removed by rinsing with potable water, not be used on food contact surfaces. If, however, such a cleaner is required then its use should be followed by a secondary cleaning step with a detergent-type product previously accepted by the CFIA or cleared by Health Canada and a final potable water rinse. The use of disinfectants and sanitizing agents on food contact surfaces also is followed with a potable water rinse. In order to be ensured of an optimum sanitizing effect, this final water rinse may be delayed until the sanitizing effect has been reached.
In certain circumstances, it is recognised that the use of a final sanitizing rinse without a subsequent potable water rinse is preferable. The following chemical substances (see Table 1) used in sanitizers without potable water rinse will be considered to be acceptable for this purpose:
| N | Chemical Substance | Maximum Concentrations of Chemical Substances |
|---|---|---|
| 1 | Chlorine releasing compounds, e.g., hypochlorites |
200 ppm of available chlorine |
| 2 | Quaternary ammonium chlorides | 200 ppm of available active quaternary ammonium compounds |
| 3 | Iodophors | 25 ppm, expressed as titratable iodine |
| 4 | Hydrogen peroxide, peracetic acid | 1100 ppm of hydrogen peroxide acetic acid solutions |
Other types of sanitizing agents, evaluated on case-by-case basis, may also be considered acceptable for use on food contact surfaces without potable water rinse. The acceptability of new and ingredients at higher concentration, and ingredients of concern used in the formulation of sanitizers will be subject to a new assessment.
The use of a sanitizing agent on food contact surfaces without a potable water rinse is subject to the following additional requirements:
Products should not be used without a potable water rinse on porous surfaces or on equipment, which is constructed in such a manner that effective drainage is not possible.
It should be noted that for sanitizers/disinfectants used on food contact surfaces without a potable water rinse, BCS will require additional information such as the residual amount of the product that will remain on food contact surfaces after application or the quantity of the product that may be incidentally transferred to foods and/or its worst-case Estimated Dietary Intake resulting from the use of the product (see Part 5.2 (c) and (d)).
Please also note that the dilution factor(s) and maximum concentrations of chemical substances used as sanitizing agents specified above should be presented on the labels of the products under "Direction for use" (see Section 5.3 (d)).
Boiler water additives (BWA), which are intended for use in food premises, are evaluated on a case-by-case basis, taking into consideration the merits of each individual submission based on its chemical formulation, recommended conditions for use, including dosage rates and product labelling. Concentration limitations have been set for the following chemicals used in boiler water systems (see Table 2):
| N | Boiler Water Additives | Maximum Concentration of Additives |
|---|---|---|
| 1 | 2-amino-2-methyl-1-propanol | 15 ppm in the steam |
| 2 | Cyclohexylamine | 10 ppm in the steam |
| 3 | Diethylaminoethanol | 15 ppm in the steam |
| 4 | Morpholine | 10 ppm in the steam |
| 5 | Octadecylamine | 3 ppm in the steam |
| 6 | N,N-bis (2-hydroxyethyl) alkyl (C12-C18) amine derived from coconut oil | 2 ppm in the steam |
| 7 | Trisodium nitrilotriacetate | 5 ppm in boiler feed water |
Steam treated with the above chemicals is not considered to be acceptable for use in the processing of milk and milk products. There is no objection to the use of blends of chemicals listed above provided that the total amine concentration of steam does not exceed 25 ppm.
It should be noted that the detailed direction for use, the maximum concentrations of additives used in boiler water systems specified above, and restrictions statements (e.g. the steam so treated does not contact milk or other dairy products) should be presented on the labels of the products under "Direction for use" (see Section 5.3 (d)).
Certain other non-volatile chemical substances are commonly used for the treatment of boiler water in food premises. Although no specific maximum concentrations have been established for these substances, their acceptability for a particular use should be determined only after an individual evaluation based on the information submitted by the manufacturer.
The use of boiler water additives in food premises is subject to the following requirements:
Please note that to promote handling of preparations containing sodium sulfite, sodium bisulfite, sodium metabisulfite, and sodium nitrite in a manner as to prevent their use in meat products, such preparations must be adequately decharacterized. The preparation is considered to be acceptable if the sulfite, bisulfite, metabisulfite and nitrite ions present are decharacterized by 33% of its weight of sodium hydroxide; by 50% of its weight of trisodium phosphate, by 100% of its weight of sodium carbonate; or if the preparation contains not less than 5% percent tannin, lignin, sodium lignosulfonate, or sodium humate.
Please note that for boiler water additives, where steam carryover may contact foods, BCS will require additional information such as the condition of use of the boiler water (i.e. temperature, pressure, pH, number of cycles, etc) and concentration levels of volatile ingredients (estimated or measured) and/or their breakdown products under normal boiler operating conditions when the steam carryover contacts food are required (see Part 5.2 (b)).
The following is a list of exempted product categories for which it is not necessary to seek a "no objection letter" for use in food processing establishments. Submissions received for products, which fall in these categories will not be evaluated by the Bureau of Chemical Safety:
Although these exempted products are not subject to the review of the Bureau of Chemical Safety, it is expected that:
