1. PURPOSE AND SCOPE

The United States Department of Agriculture’s Federal Grain Inspection Service (FGIS)

provides official mycotoxin testing services throughout the United States for domestic and

export grains, oilseeds, and processed-grain commodities. Official testing services are

available for aflatoxins, deoxynivalenol, fumonisins, ochratoxin A, and zearalenone. Testing at

field locations requires rapid, simple, inexpensive, and accurate methods to effectively assess

the quality of U.S. grain. An important part of quality assurance for official mycotoxin testing is

the Mycotoxin Test Kit Evaluation (MTKE) Program, through which FGIS evaluates and

certifies the conformance of quantitative rapid mycotoxin test methods to specific criteria. Only

rapid test kits having FGIS certification are approved for official mycotoxin testing. Updated

test kit design criteria and performance specifications for quantitative aflatoxin test kits are

covered herein. These requirements are effective January 1, 2023.

NOTE: Until January 1, 2024, applicants may submit test kits for evaluation under the

previous requirements issued in June 2018. Certificates issued under the June 2018

requirements will expire one year from the date of issuance. For a copy of the previous

requirements, contact the MTKE Program by email at MTKE.Program@usda.gov.

2. SUMMARY OF TEST KIT EVALUATION PROCESS

FGIS establishes design criteria and performance specifications that mycotoxin test kits must

meet to be considered for use in official inspection. Test kit manufacturers may submit a test

kit for evaluation by FGIS staff. Submission packets are reviewed by FGIS staff in order of

receipt. The submission packet must include all documentation needed to demonstrate that the

test kit meets the established FGIS design criteria and performance specifications. Incomplete

submissions, submission not conforming to FGIS requirements, and submissions containing

excessive errors will be rejected. If the submission is accepted, arrangements for FGIS analyst

training and performance verification will be made with the applicant. The FGIS analysts that

conduct performance verification testing will be trained in the operation of the test kit by the

applicant. A maximum of two analysts from the test kit manufacturer may participate in the

performance verification.

If the test kit meets all design and performance requirements, FGIS issues a Certificate of

Conformance (COC) stating that the test kit has met the criteria. Upon issuance of the official

test kit instructions, the test kit may be used for official inspection. The COC will be valid for

three years from its date of issuance. Renewal of a COC requires a full submission and

evaluation.

If the test kit fails to meet all of the criteria specified herein, the test kit can be resubmitted after

the manufacturer has identified and resolved the root cause of the failure. When the test kit is

resubmitted, the applicant must state the root cause and corrective action that was taken to

bring the test kit into conformance with FGIS requirements, and a new data packet must be

submitted.

3. PROGRAM CONTACT INFORMATION

Send submission packets via email to MTKE. Program@usda.gov. For questions and

comments regarding mycotoxin test kit evaluation, contact the Mycotoxin Test Kit Evaluation

Program at MTKE.Program.@usda.gov.

4. FEE FOR TEST KIT EVALUATION

FGIS will assess a fee for evaluating a test kit, including all documentation reviews. Payment is

expected within 30 days of the invoice date.

5. DEFINITIONS

Aflatoxins. The sum of aflatoxin B1, B2, G1, and G2.

Applicant. The manufacturer of the test kit under evaluation.

Fortified Samples. Samples to which a known amount of aflatoxins was previously added using

a standard solution.

Lower Conformance Limit. The lowest concentration at which the test kit has demonstrated

acceptable quantitation of aflatoxins according to FGIS requirements. Submitted test kits must

have a lower conformance limit (LCL) of 5.0 parts per billion (ppb).

Upper Conformance Limit. The highest concentration at which the test kit has demonstrated

acceptable quantitation of aflatoxins according to FGIS requirements. Submitted test kits must

have an upper conformance limit (UCL) of at least 300 ppb aflatoxins. Submissions with a

desired UCL of greater than 300 ppb must be accompanied by additional performance data

from the applicant at this level, and the test kit must pass a FGIS performance verification study

at the proposed limit.

Range of Conformance. The concentration range for which a test kit conforms to FGIS

accuracy requirements. This range is bracketed by the upper and lower conformance limits.

The minimum range of conformance required by FGIS for quantitative aflatoxin test kits is 5.0 –

300 ppb.

Range of Quantitation. The concentration range associated with a single analysis. A test kit

may have more than one range of quantitation if additional dilutions, reader calibrations, and

analyses are needed to cover the range of conformance.

Test Kit. A commercially packaged system of the principal or key components of an analytical

method used to determine the presence of aflatoxins in specified matrices. Test kits include

directions for their use and are self-contained, complete analytical systems; however, they may

require supporting supplies and equipment. The key components frequently represent

proprietary items that may be available only from the manufacturer of the test kit.

6. DESIGN AND PERFORMANCE REQUIREMENTS

a. Grinding and Homogenizing Sample Materials

All commodities used in the performance studies must be ground so that at least 95%

passes through a U.S. Standard No. 20 sieve and mixed thoroughly to ensure

homogeneity prior to removing samples for testing.
Design Criteria and Test Performance Specifications 

for Quantitative Aflatoxin Test Kits

Effective January 1, 2023

Page 4 

b. Sample Storage

Sample materials must be stored in sealed containers at ≤ 8 °C, and refrigerated

samples must be allowed to reach room temperature before use.

c. Preparation of Reference Materials

A validated analytical reference method, preferably the FGIS method, must be used for

determining the aflatoxin concentration in all naturally contaminated materials and

materials used to prepare fortified samples that are used in the performance studies.

The applicant must state what analytical method was used to certify the reference

materials. If a method other than the current FGIS reference method is used, a copy of

the method instructions and validation report or literature reference must be supplied by

the applicant. This method must have performance characteristics (accuracy and

precision) that are equivalent to the FGIS reference method. Determination of method

equivalence resides with the applicant. The FGIS reference method is available upon

request.

The aflatoxin concentration in each naturally contaminated reference material must be

determined by analyzing the minimum of twenty-one samples (50.0 ± 0.2 g each)

across three batches (seven samples in each batch) using the FGIS reference method

or equivalent method. For use of a material in the test kit trials, the mean aflatoxin

concentration must be within ± 15% of the target concentration.

Aflatoxin-contaminated materials produced through fungal inoculation and growth under

laboratory conditions may be used in place of naturally contaminated materials. A

relevant fungal species and strain isolated from the Continental United States must be

used for producing the contaminated commodity. Although inoculation is allowed for

generating contaminated samples, the test kit will be expected to meet FGIS

performance criteria when determining aflatoxins on any naturally contaminated grain or

processed-grain commodity sample originating in the United States.

d. Preparation of Standard Solutions

The purity of the neat aflatoxin standards must be ≥ 98%. A certificate of analysis from

the supplier of each neat standard must be provided in the submission packet.

For each standard solution containing a single aflatoxin isomer, the concentration of the

aflatoxin isomer must be determined by UV spectrophotometry as specified in the FGIS

reference method.

The standard solution used for fortification of samples must be prepared using a

concentration ratio of 10:1:1:1 for aflatoxin B1:B2:G1:G2, respectively.

e. Conditions of Analysis

All analyses must be conducted at room temperature (i.e., 20 – 24 °C) unless specified

otherwise.
Design Criteria and Test Performance Specifications 

for Quantitative Aflatoxin Test Kits

Effective January 1, 2023

Page 5 

When generating test kit data for submission, all samples must be labeled with a code 

and fully randomized so that the analyst conducting the test cannot know the level of 

analyte. Furthermore, the same person performing the analyses must not prepare the 

test samples.

f. Written Instructions for Test Kit Use

The applicant must provide complete, written instructions for use of the test kit that

accurately reflect the procedures followed to generate the data in the submission.

These instructions must be formatted following the guidelines in Appendix B. FGIS will

follow these written instructions during training and when verifying test kit performance.

g. Multiple Procedures

A single, well-defined, analytical method will be evaluated for each submission. Multiple

procedures, such as options for the use of blending vs. shaking for sample extraction or

filtration vs. centrifugation for sample clarification, require a full data submission for

each procedure; each procedure will be evaluated by FGIS. Other instances of multiple

procedures may require a full data submission packet and evaluation for each

procedure depending on the significance of the variation. FGIS will determine the need

of a separate evaluation on a case-by-case basis taking into consideration the possible

effect of procedural variation and its benefit to the official inspection system. Prior to test

kit submission, the MTKE Program should be contacted for further guidance on data

submission and evaluation requirements in such cases.

h. Time for Completion of Analysis

For a pre-ground sample, the test kit procedure must be capable of generating an

accurate result across the minimum required range of 5.0 – 300 ppb aflatoxins in 30

minutes or less (i.e., time from extraction to final result). If the test kit has a limited

quantitative range and the need for additional dilution and analysis to cover the

minimum range of conformance, the 30-minute limit includes all steps needed to

generate the final result.

i. Significant Figures and Unit of Measurement

The test kit reader (or detector) must display results using at least two significant figures

in parts per billion (ppb). Test kit results will be evaluated using two significant figures.

When rounding to two significant figures, the number will be rounded up when the third

digit is 5 or more. For example, 5.25 ppb would be rounded to 5.3 ppb, and 5.24 ppb

would be rounded to 5.2 ppb. To avoid rounding error, at least three significant figures

should be used when performing calculations, and only the calculated result should be

rounded to two significant figures.

j. Accuracy

(1) Minimum Required Range of Conformance

The applicant must provide data demonstrating accuracy of the test kit using

naturally contaminated corn at the targeted concentrations of 5.0, 20, 100, and

300 ppb aflatoxins.

Three analysts must each extract seven separate samples at each concentration

according to the test kit instructions. Each analyst must use a different

manufacturing lot for the test kit materials and a different reader. All samples

must be analyzed as if the concentrations were unknown.

At least 95% of the results (20 out of 21) for each concentration level must be

within the acceptable ranges specified in Table 1. The acceptable range is

determined by the following equation.

Acceptable Range (ppb) = y� ± 0.02∙RSDmax∙y�

where y� is the mean concentration determined in the reference material 

analyses, and RSDmax is maximum relative standard deviation listed in Table 1

for the target concentration.

300 16 48 200 – 400

*± 15% 

(2) Extended Range of Conformance

For an UCL above 300 ppb aflatoxins, the applicant is required to provide data

demonstrating the test kit’s capability for meeting the performance requirements

at the proposed UCL. The applicant must also provide the analytical procedure

used to generate the supporting data. The use of naturally contaminated

materials to generate supporting data is preferred; however, fortified samples are

acceptable. The FGIS reference method or equivalent must be used to

characterize the naturally contaminated material as described previously. The

standard solution used for fortification of additional commodity samples must be

prepared according to Section 6.d. using a concentration ratio of 10:1:1:1 for

aflatoxin B1:B2:G1:G2, respectively. After fortification, samples must be left open

in a fume hood for approximately 30 minutes to allow the solvent to evaporate

prior to extraction.

Three analysts must each extract seven separate samples (50.0 ± 0.2 g each) at

the UCL according to the test kit instructions. Each analyst must use a different

manufacturing lot for the test kit materials and a different reader. All samples

must be analyzed as if the concentrations were unknown. At least 95% of the 

results (20 out of 21) must be within the range specified in Table 2.

UCL > 300 16 0.16·UCL UCL ± 0.32·UCL

(3) Multiple Ranges of Quantitation

Additional data must be submitted when a test kit uses multiple ranges of

quantitation.

The applicant must provide data demonstrating accuracy of the test kit using 21

samples (50 ± 0.2 g each) of corn naturally contaminated at the concentration

level where the two ranges meet following each protocol for extraction and

analysis consistent with Section 6.j.(1). Both analysis procedures must be tested

at this level. The same set of extracts should be used to test the procedure for

each range of quantitation. Twenty of the 21 results must be within the

acceptable range for each analysis procedure.

The acceptable range is determined using the following equation.

Acceptable Range (ppb) = y� ± 0.02∙RSDmax∙y� ; 

where y� = mean concentration determined in the reference material preparation,

and RSDmax = 31.572·C-0.149; where C is the aflatoxin concentration in ppb for 

concentrations between 5.0 – 100 ppb not listed in Table 1. For concentrations 

100 ppb and above, the RSDmax = 16%.

Example: For a test kit that has the two ranges of quantitation, 5.0 – 50 ppb and 

50 – 300 ppb, the applicant must provide data for each applicable analysis 

procedure using reference material with a mean concentration of 50 ppb ± 15%. 

If the mean concentration in the reference material was 50.0 ppb, the RSDmax

would be 17.63%, and the acceptable range would be 32 – 68 ppb. 

(4) Additional Commodities

Application for approval of additional commodities can be made at the time of

original submission or after the test kit has been approved. The list of acceptable

commodities is found in Appendix C. Contact the MTKE Program for possible

incorporation of additional commodities not included in this list. The applicant

must provide the additional commodity name and definition.

Applicants must provide data in accordance with the following guidelines for each

additional commodity and the specific procedures followed for analysis. Fortified

samples can be used to generate the supporting data; however, the test kit will

also be expected to adhere to the accuracy requirements for naturally

contaminated samples.
Design Criteria and Test Performance Specifications 

for Quantitative Aflatoxin Test Kits

Effective January 1, 2023

Page 8 

The standard solution used for fortification of additional commodity samples must 

be prepared according to Section 6.d using a concentration ratio of 10:1:1:1 for 

aflatoxin B1:B2:G1:G2, respectively. After fortification, samples must be left open 

in a fume hood for approximately 30 minutes to allow the solvent to evaporate 

prior to extraction. FGIS may verify performance of the test kit using fortified or 

naturally contaminated samples.

Uncontaminated (blank) samples of each additional commodity must be ground 

with a mill so that at least 95% of the material passes through a U.S. Standard 

No. 20 sieve. Ground portions must be mixed to ensure homogeneity and divided 

in a manner to maintain sample representativeness. A description of the specific 

equipment and procedures used in grinding, mixing, sieving processes, and 

dividing must be provided.

For each additional commodity, five fortified samples must be tested at each 

targeted level of 5.0, 20, 100, and 300 ppb aflatoxins. For an UCL limit above 

300 ppb, five samples at the proposed UCL must also be included in the study.

One analyst must extract all samples according to the test kit instructions. For 

each additional commodity, the analyst must analyze one aliquot of each extract.

All of the results must be within the ranges specified for the fortification levels 

according to Table 1 and Table 2.

k. Hazardous Materials and Waste

Use of the test kit must not expose employees, without access to fume hood or

respirator, to toxic or hazardous substances beyond OSHA Standards specified in 29

CFR. The test kit must not require special waste disposal (e.g., special waste disposal

includes all radioactive material, P-listed hazardous waste, or hazardous waste listed for

its toxicity characteristic as defined in 40 CFR). The applicant must attest that the test

kit meets these requirements. Safety Data Sheets (SDS) must be provided for all

materials used in the test kit.

l. Sensitivity to Electromagnetic Fields

Electronic equipment used with the test kit must not be sensitive to electromagnetic

fields spanning a frequency of 800 MHz to 6 GHz and an intensity of 1.0 volts/ meter to

5.0 volts/meter. Electric fields must not cause the equipment display to be corrupted or

otherwise affect readings during the test. The applicant must provide a statement of

certification from an accredited laboratory verifying the equipment meets these

requirements. Laboratories conducting the electromagnetic study must be accredited by

a signatory of the International Laboratory Accreditation Cooperation Mutual

Recognition Arrangement. Tests must be performed according to the guidelines in

Electromagnetic Compatibility (IEC 61000-4-3; International Electrotechnical

Commission, Geneva, Switzerland).
Design Criteria and Test Performance Specifications 

for Quantitative Aflatoxin Test Kits

Effective January 1, 2023

Page 9 

m. Temperature Sensitivity

Corn that is naturally contaminated with aflatoxins at 20 ppb must be used in the

temperature sensitivity study. Seven samples (50.0 ± 0.2 g each) must be extracted,

and one analysis of each extract must be performed at each of three temperature

conditions (i.e., 18 °C, 24 °C, and 30°C) to yield seven analyses at each temperature.

Extracted samples must be protected from light during this study. All test materials (i.e.,

extracts and test kit components) must be allowed to equilibrate to the targeted

temperature for one hour using an environmental chamber prior to analysis. At least

95% of the results (20 out of 21) must be within the range as specified in Table 1.

n. Shelf Life

The applicant must provide a shelf life label statement and supporting data under the

recommended storage conditions for all materials and reagents used in their tests. In

addition, the applicant must provide the procedure followed for generating and

analyzing the stability data. Real-time data is preferred for supporting stability claims;

however, accelerated aging based on the Arrhenius equation may be used. The stability

data must demonstrate conformance to all applicable criteria in this document.

o. FGIS Performance Verification

After acceptance of a submission, the applicant will be contacted to arrange for training

of the analysts who will conduct the FGIS performance verification. The training allows

the applicant to provide hands-on training to the FGIS analysts for the sample

preparation and equipment operation procedures. The analysts will receive up to one

day of training in the use of each test kit by the applicant or designee. A maximum of

two analysts from the test kit manufacturer may participate in the performance

verification. The applicant is required to provide all equipment and supplies needed to

complete the training and FGIS performance verification. Any naturally contaminated

materials used for the performance verification will be characterized as specified in

Section 6.c using the current FGIS reference method.

(1) Minimum Required Range of Conformance

FGIS will verify the test kit’s performance following the procedure as described in

Section 6.j.(1) at the targeted levels of 5.0, 20, and 300 ppb aflatoxins.

(2) Extended Range of Conformance

For an UCL greater than 300 ppb, FGIS will verify the test kit’s performance

following the procedure as described in Section 6.j.(2).

7. MANUFACTURER’S NOTIFICATION RESPONSIBILITIES

Manufacturers holding a COC must notify the MTKE Program in writing when any changes or

alterations are made to the test kit, including reagents, shelf life of test kit materials, equipment

used in the test kit, software or calibration revisions, or any part of the analytical method.

Alterations to a test kit will be evaluated by FGIS for significance and may require another full

FGIS performance verification. Failure to notify FGIS of such changes will serve as grounds for
Design Criteria and Test Performance Specifications 

for Quantitative Aflatoxin Test Kits

Effective January 1, 2023

Page 10

immediate cancellation of the COC. Changes to the kit packaging, brochure, or other 

marketing information are exempt from this requirement.
