The test results of a food safety comprehensive analyzer usually need to include basic sample information, detailed testing items, result judgment, quality control indicators, and report compliance to ensure the scientific and traceable nature of the data. The following is the specific composition and explanation:

1、 Sample identification and detection background

1. Basic information of the sample

Sample names such as "certain brand soy sauce", "fresh pork", "vegetable salad", etc. should be consistent with the actual samples submitted for inspection.

Sample number: Unique code (such as "SP20250626001"), associated with sampling time, location, and batch.

Sampling information:

Sampling date (such as June 26, 2025), sampling person, sampling location (such as a supermarket shelf).

Sample status (fresh/frozen/intact packaging), specifications (e.g. 500mL/bottle).

Entrustment information: Name and contact information of the commissioning unit/individual, testing purpose (such as regulatory sampling, enterprise self inspection).

2. Testing environment and conditions

Testing date, laboratory temperature (e.g. 25 ± 2 ℃), humidity (e.g. 50 ± 5% RH).

Instrument model (such as FS-9000 model of a certain brand), calibration status (with calibration certificate number attached).

2、 Testing items and presentation of results

1. Microorganisms and biosafety indicators

Pathogenic bacteria: Escherichia coli O157: H7, Salmonella, Staphylococcus aureus, etc., with results indicated as "detected/not detected" (e.g. "Salmonella: not detected (n=5, c=0)").

Microbial limit: total bacterial count (CFU/g), coliform group (MPN/g), such as "total bacterial count: 3.2 × 10 ³ CFU/g (≤ 10 ⁴ CFU/g)".

Virus detection: such as norovirus, hepatitis A virus (applicable to raw food and aquatic products, etc.), indicated by PCR amplification Ct value or "positive/negative".

2. Other safety indicators

Illegal additives: clenbuterol, suspended white pellets, etc., with results such as "clenbuterol I: not detected (detection limit 0.01mg/kg)".

Allergens, such as milk, eggs, and peanuts, are tested for antibody potency using ELISA (e.g. "milk protein: negative (<50IU/mL)").

Physical and chemical properties: pH value, acid value, peroxide value, etc. (e.g. "Acid value: 1.5mgKOH/g (≤ 3.0mgKOH/g)").

3、 Result determination and compliance explanation

1. Standard comparison and conclusion

According to the standards: clarify the national standards for testing (such as GB2763-2021 "Maximum Residue Limits for Pesticides in Food" and GB2762-2022 "Limits for Pollutants in Food").

Qualification assessment:

Single result: For example, "lead content of 0.12mg/kg meets the limit requirements for grain products in GB2762-2022".

Comprehensive conclusion: "After testing, XX items in the tested items meet the national standards, and the sample is judged to be qualified/unqualified.

2. Suggestions for handling exceeding standards

If the result exceeds the standard, it should be noted that 'XX index exceeds the national standard by XX times, it is recommended to re-examine the sample or trace the production process'.
