An allergen cross-contamination log records your daily verification that prep stations are separated, dedicated utensils are in use, surfaces are sanitized between allergen-containing preparations, and staff are trained. PassMyKitchen's allergen log lets you track all 9 FDA-recognized allergens, verify separation and labeling controls per allergen, and document cross-contamination incidents with required corrective actions. Here is how to use it.
For the daily workflow that includes allergen checks, see daily food safety routine under 5 minutes. For inspector preparation, see how to use Inspector Mode. For a full compliance overview, see our food safety compliance score explained.
Why allergen logging matters
Food allergies send roughly 30,000 people to the emergency room every year in the United States, according to the CDC. For food businesses, an allergic reaction traced back to your kitchen is not just a health crisis. It is a liability event, a potential lawsuit, and grounds for a critical violation.
The Food Allergen Labeling and Consumer Protection Act (FALCPA) identifies 9 major allergens that account for the vast majority of serious allergic reactions. The FDA Food Code requires food businesses to demonstrate knowledge of major food allergens and to implement controls that prevent cross-contact.
Cross-contact (sometimes called cross-contamination in allergen contexts) happens when a food allergen is unintentionally transferred to a food that does not contain that allergen. A knife used to cut a peanut butter sandwich, then used unwashed to slice a plain turkey sandwich, transfers peanut protein to the turkey. Unlike bacterial contamination, allergen proteins cannot be destroyed by cooking. Once cross-contact occurs, the food is unsafe for an allergic individual.
Allergen logging proves to inspectors that you actively manage allergen controls every day. A stack of timestamped records showing that your stations were separated, utensils were dedicated, surfaces were sanitized, and staff were trained tells the inspector that you are not relying on luck. You have a system. Cloud kitchens operating multiple brands from a single kitchen face especially high risk, because allergen-containing ingredients from one brand can easily migrate to another brand's prep area. For more on cloud kitchen compliance challenges, see our cloud kitchen compliance guide.
How to log an allergen check in PassMyKitchen
Step 1: Navigate to the allergen log
From the sidebar, tap "Logs." On the Logs page, tap the "Allergens" card. On the Allergen Logs page, tap "Log allergen check" in the top right to open the allergen log form. The page title reads "Log Allergen Check" with the subtitle "Record allergen controls and cross-contamination prevention."
Step 2: Select the check type
Choose one of four check types using the radio buttons:
- Daily check for your routine daily allergen verification
- Pre-shift check for verifying controls before a specific shift begins
- Post-incident for documenting the state of controls after a cross-contamination event
- Audit for formal internal or external allergen audits
The check type appears as a badge in your log history, so you and your inspector can see what prompted each entry. For a complete audit preparation workflow, see our food safety audit checklist.
Step 3: Complete the general allergen controls
Four checkboxes appear under the general allergen controls section. All four are checked by default:
- Prep stations are separated for allergen-containing items. This confirms you have physically designated areas for allergen-containing preparations.
- Dedicated utensils and equipment used for allergen items. This verifies that cutting boards, knives, and other tools used with allergens are not shared.
- Surfaces cleaned and sanitized between allergen-containing preparations. This confirms that prep surfaces were cleaned before switching between allergen and non-allergen items.
- All staff on duty have completed allergen awareness training. This verifies that every team member working today has been trained on allergen protocols.
If you uncheck any of these controls, a warning badge appears: "One or more allergen controls were not met. Consider documenting corrective actions." This does not block you from saving, but it flags the entry as non-compliant in your history.
Step 4: Review allergen-specific checks
The allergen-specific checks section loads the 9 FDA-recognized allergens from the system. For each allergen present in your current preparation, mark the "Present in prep" checkbox. Details on this section are covered below.
Step 5: Report incidents if applicable
If a cross-contamination incident occurred, check the "A cross-contamination incident occurred" checkbox and complete the required fields. See the incident handling section below for details.
Step 6: Add notes and save
An optional notes field labeled "Any additional notes about today's allergen controls" lets you record context like "New staff member shadowed allergen prep station" or "Switched to color-coded cutting boards." Tap "Save allergen check" to save the entry with an automatic timestamp.
Understanding the allergen-specific checks
The allergen-specific checks section pulls the 9 FDA-recognized major allergens: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. These are the allergens identified under FALCPA that require labeling and control in food service operations.
For each allergen, you can mark it as "Present in prep" using a checkbox. When checked, a "Present in prep" badge appears next to the allergen name, and an expandable section opens with two sub-checkboxes:
- Separation from other items verified. This confirms the allergen-containing ingredient was kept isolated from other foods during prep.
- Labeling verified on all containers. This confirms that every container holding this allergen-containing ingredient is properly labeled.
A notes field for each present allergen lets you add specific details, such as "Tree nut dessert prepped on station 3 only" or "Fish stored on bottom shelf per protocol."
If your menu does not currently include a particular allergen, leave it unchecked. Your log will reflect only the allergens that were relevant to that day's operation, giving inspectors an accurate picture of your actual allergen exposure.
Handling cross-contamination incidents
When a cross-contamination incident occurs, check the "A cross-contamination incident occurred" checkbox. This opens a danger-styled section with two required fields:
- Describe the incident. A text area with placeholder text "What happened and which allergens were involved." Describe exactly what occurred: which allergen was transferred, what food was affected, how it was discovered, and whether any contaminated food reached a customer.
- Corrective action taken. A text area with placeholder text "Steps taken to address the incident and prevent recurrence." Document what you did immediately (discarding contaminated food, re-sanitizing surfaces, alerting staff) and what you will change to prevent it from happening again (revised prep layout, additional training, new color-coded equipment).
Incident entries are clearly marked in your log history with a visible incident banner and a danger-styled left border. This documentation serves two purposes: it proves to inspectors that you respond to incidents proactively, and it creates a record that your team learns from mistakes. A kitchen that documents zero incidents is not necessarily safer than one that documents and resolves them. Inspectors understand this.

Viewing allergen log history
The Allergen Logs history page gives you a dashboard view of your allergen compliance over time.
Stats cards
Three summary cards appear at the top of the page:
- Allergen checks shows the total number of allergen checks logged in the selected time period.
- Compliance rate shows the percentage of checks where all four general allergen controls were met.
- Incidents shows the total number of cross-contamination incidents reported.
Filters
Time-based filter presets let you view 7 days, 30 days, or 90 days of history. A compliance filter lets you narrow results to All, Compliant, or Non-compliant entries. Use these filters to quickly surface problem areas or verify consistent compliance over a period.
Log cards
Each log entry displays the date and time, check type badge (Daily check, Pre-shift check, Post-incident, or Audit), and a Non-compliant badge if any general control was not met. Four control status icons show at a glance whether Stations, Utensils, Surfaces, and Training passed. The card also lists which allergens were present and shows an incident banner if one was reported. The name of the team member who logged the entry appears at the bottom.
Non-compliant entries have a danger-colored left border so they stand out immediately. This visual distinction helps you spot patterns, like recurring issues with surface sanitization on busy weekends. For a broader view of your compliance metrics, see food safety compliance score explained.
Allergen logging for different business types
Allergen logging in PassMyKitchen is available for all business types. The same form works whether you run a restaurant, food truck, cloud kitchen, or catering operation, but the way you use it varies based on your setup.
Food trucks
Limited prep space on a food truck means allergen separation requires extra discipline. You may not have room for a dedicated allergen prep station, so documenting that you sanitize between preparations and use separate utensils becomes even more important. Log a pre-shift check before every service to verify your controls are in place. For more food truck guidance, see our food truck compliance resources.
Cloud kitchens
Cloud kitchens running multiple brands from one facility face the highest cross-contamination risk. Priya runs three brands from her cloud kitchen: a nut-heavy dessert brand, a shellfish-forward poke concept, and a vegan bowl line marketed as allergen-friendly. Without careful allergen logging, a trace of tree nut from brand one could end up in a "nut-free" bowl from brand three. Daily allergen checks with per-allergen separation verification help Priya prove that each brand's prep area is isolated and controlled. See our cloud kitchen compliance guide for more on managing multi-brand operations.
Caterers
Caterers face event-specific allergen challenges. A wedding with a guest who has a severe shellfish allergy requires different controls than a corporate lunch with no allergen requests. Use the notes field to document event-specific allergen requirements, and log a pre-shift check before each event to verify that your team has set up allergen controls for that event's specific needs.

Frequently asked questions
Do I need to log allergen checks every day?
You should log at minimum one daily check on every day you operate. Pre-shift checks add a second layer of verification for high-volume days or when new staff are on duty. Post-incident and audit check types are used as needed. Consistent daily logging builds the record that inspectors want to see.
What are the 9 FDA-recognized major allergens?
The 9 major allergens under FALCPA are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Sesame was added as the ninth allergen in January 2023. PassMyKitchen loads all 9 automatically in the allergen-specific checks section, so you do not need to remember the list.
Is allergen logging available on the Starter plan?
Allergen logging is available across PassMyKitchen plans. Check pricing for full details on what each plan includes.
What if my menu does not contain any major allergens?
If none of the 9 FDA allergens are present in your current menu, you can still log daily checks to verify your general controls (station separation, dedicated utensils, surface sanitization, and staff training). Leave all allergens unchecked in the allergen-specific section. This creates a record showing you actively verified that no allergens were in use, which is still valuable documentation. For requirements under the FDA Food Code, see our FDA Food Code requirements guide.
How does my allergen log appear in Inspector Mode?
When you activate Inspector Mode, your allergen logs are accessible alongside your temperature, cleaning, and receiving logs. Inspectors see the same stats cards, compliance rate, and individual log entries that you see. Non-compliant entries and incidents are clearly flagged so the inspector can review your response to any issues. For a walkthrough of Inspector Mode, see how to use Inspector Mode.
