A. FDA's Most Likely Hazards/Control Measures for Juice

FDA strongly recommends that the following hazards be considered in your HACCP plan.  This means that you should state them as significant hazards in your Hazard Analysis and control them as CCP’s unless you can demonstrate otherwise.

Table 1. Most Likely Hazards/Control Measures for Juice

Hazard Identity

Hazard rationale

Possible control measures

Pathogens/biological

Unless you produce one of the types of juice listed in footnote #12, or a low acid juice not subject to the Low Acid Canned Foods regulations (21 CFR Part 113) one of the pathogens listed in footnote #13 is likely to be the "pertinent microorganism" for your required 5-log pathogen reduction treatment.

  1. Pasteurization
  2. UV radiation

Patulin/chemical

Patulin is a mycotoxin that can occur on rotten, moldy, bruised or damaged apples, and may occur at hazardous levels if such apples are used to make juice

  1. Supplier guarantee for each shipment; only apples harvested to exclude fallen fruit were supplied
  2. Cull or trim apples after storage to remove rotten, moldy, bruised and damaged apples

Milk residue (an undeclared allergen) in juice/chemical

May occur in juice processed using equipment also used to process milk or dairy products

CCP or SSOP control for adequate cleaning of processing equipment between a milk run and a juice run

Fragments from glass containers/physical

Glass fragments in juice can pose a risk of injury if ingested

Check processing line for evidence of glass breakage (if containers are mechanically handled)

Pass product through x-ray equipment or other defect rejection system

Pass product through separation device such as a screen

Check containers prior to filling for glass breakage (if containers are manually handled)

Metal Fragments

Metal fragments in juice can pose a risk of injury if ingested

Check equipment for evidence of broken or missing metal parts that may enter the juice

Pass product through metal detection equipment

Pass product through separation device such as a screen or magnet (if the metal is ferrous, e.g., a steel grinder blade)

B. Recommended Control Measures for Significant Hazards

FDA offers these suggestions for control measures for significant hazards.  Use them unless you can demonstrate that alternatives are equally effective.

1. Control Measures for Significant Biological Hazards

1.1. Thermal systems

For apple juice at pH values of 4.0 or less, FDA recommends the following thermal processes to achieve a 5-log reduction for oocysts of Cryptosporidium parvum based upon a conservative evaluation of the available scientific data;

  • 160 degrees F for 6 seconds (recommended treatment conditions in New York),
  • 165 degrees F for 2.8 seconds,
  • 170 degrees F for 1.3 seconds,
  • 175 degrees F for 0.6 seconds, or
  • 180 degrees F for 0.3 seconds

1.2. UV systems

If you are using a UV "pasteurizer", consult with the manufacturer to determine proper settings to achieve an microbial kill equivalent to the 5-log heat treatment


2. Control Measures for Significant Chemical Hazards

2.1. If the receiving of apples is a CCP:

A supplier guarantee specifying that only apples harvested to exclude fallen fruit were supplied in the shipment is likely to be an effective control measure for patulin. Under such an approach:

  • The existence of the supplier guarantee for each shipment of incoming fruit specifying that only apples harvested to exclude fallen fruit were supplied in the shipment would be the critical limit. For a small processor who harvests apples from his own orchard, we recommend, in lieu of a supplier guarantee, that the processor's apple pickers be instructed not to harvest fallen fruit and the processor confirm that the workers are adhering to the instructions.
  • A monitoring procedure would be to confirm visually the existence of the guarantee for each incoming shipment of apples.
  • The corrective action procedure would be to reject any shipment of fruit not accompanied by a guarantee from the supplier.
  • The verification procedure could consist of periodic auditing of the supplier to ensure that the supplier is following the provisions of the guarantee, or testing the juice periodically to confirm that it does not contain high levels of patulin. We recommend that processor's who rely on guarantees or certificates from suppliers to control a hazard couple these types of controls with a strong verification procedure, such as visiting the farm periodically or periodically testing the juice.

2.2. If culling or trimming apples after storage is a CCP:

  • The culling or trimming of the fruit during the sorting step after storage to eliminate moldy, rotten, bruised, and damaged (e.g., from birds or insects) fruit is likely to be an effective control measure.
  • The use of only apples or apple portions free of mold, rot, bruising, and other damage would be the critical limit.
  • A monitoring procedure would be to inspect apples at the sorting step to ensure that the apples are free of rot, mold, bruising, and other damage.
  • The corrective action procedure would be to cull or trim any apples that show mold, rot, bruising, or other damage. In practice, we recommend that you establish visual or other criteria for what constitutes a damaged apple that should be culled. We further recommend that criteria be established based upon validation data showing that juice made from apples culled using the criteria do not contain unacceptable levels of patulin.
  • The verification procedure could consist of periodically testing the juice to confirm that the juice does not contain high levels of patulin and reviewing records of monitoring, corrective action, and verification.

2.3. If you are also pasteurizing milk in the same facility:

If you process juice on equipment that also has been used to process a food that can cause allergic reactions, sucha as milk, FDA recommends that you implement CCP or rigorous SSOP controls that will ensure that the equipment has been cleaned properly before it is used to process juice.

For example, if you process milk on equipment also used to process juice, we recommend that you clean the equipment to eliminate the milk residues before using the equipment to process juice.

An appropriate SSOP might be to establish a procedure for cleaning your equipment with a cleaning solution, e.g., a pre-rinse, followed by a caustic wash, followed by a rinse. The procedure could include maintaining a log of what foods, e.g., milk, eggnog, soy drinks, were processed on your equipment, the sequence in which the foods were processed, and how/when the equipment was cleaned. Your operator could check that log prior to starting any production run for juice. Your control could provide that the equipment would not be used for juice until the prescribed cleaning procedure was carried out, and recorded in the log (See Example SSOP in section VII C). We recommend that you initially validate the effectiveness of the cleaning procedure by conducting tests for milk protein residue on the equipment after running the cleaning. We also recommend that you establish a procedure to monitor the efficacy of the cleaning process, e.g., swabbing the equipment surfaces and testing the swabs for milk protein residue.

A CCP procedure could similarly be based upon a pre-rinse, caustic wash, followed by rinse procedure. We do recommend that the parameters of the procedure such as time, temperature, and percent caustic, initially be validated for the effective removal of milk protein from the processing equipment and monitoring of the parameters as critical limits be carried out (See Example CCP in section VII C).

Whether an SSOP or a CCP is used, you should consider whether the equipment's design makes cleaning difficult absent disassembly of the equipment. If necessary to achieve effective cleaning, we recommend that you disassemble the equipment as part of the cleaning process.

3. Control Measures for Significant Physical Hazards

3.1 Glass Fragments

FDA recommends several ways to establish control measures for glass fragments in juice.

One way is the use of on-line glass detection equipment such as x-ray detection. In this method, the product itself is continuously monitored after the last step at which glass inclusion is reasonably likely to occur (e.g. after bottling and sealing of the juice). This could be, for example, at a process step designated for x-ray examination. The critical limit might be designated as "no glass fragments in the finished product." The following illustrates the elements that might be entered into your HACCP plan.

  • What is the critical limit? No glass fragments in finished product (Note: FDA's Health Hazard Evaluation Board has supported regulatory action against product with glass fragments of 0.3" (7 mm) to 1.0" (25 mm) in length. See also FDA Compliance Policy Guide 555.425).
  • What will be monitored? The presence of glass fragments in containers passing the CCP
  • How is monitoring done? Use of x-ray equipment or other defect rejection system
  • How often? Continuous; each container is subjected to detection. For x-ray equipment and other defect rejection systems, we recommend that you confirm that the device is operating correctly, at least at the start of each production day
  • Who will perform the monitoring? For x-ray detection and other defect rejection systems, the equipment itself performs monitoring. We recommend that you check at least once per day to ensure that the device is operating.

Another way to control glass fragments, applicable in operations where the containers are manually (not mechanically) handled and sealed, involves inspecting glass containers visually before they are filled to ensure that glass fragments are not present in the containers. An appropriately trained individual at a container inspection step in the process may do this. We recommend that there be a check at the start of production to ensure that the appropriate personnel are assigned to the processing step where the inspection will occur. The critical limit might be designated as "no glass fragments in empty glass containers at the container inspection step."

A third way to control glass fragments is visual inspection at steps in the process where glass breakage can result in glass entering the juice, such as the glass container receiving, glass container storage, mechanical conveying, mechanical filling, and mechanical capping. The inspection looks for any evidence of glass breakage in those areas. CCPs might be identified as the glass receiving and storage steps and the mechanical conveying, filling and capping steps. The critical limit might be designated as "no broken glass at the CCPs for glass inclusion." If broken glass is observed, the line is stopped, the glass is removed, and the product that has moved through that area since the last inspection is placed on hold for further action as appropriate, e.g. to be run through off-line glass detection equipment, to be destroyed, to be diverted to non-food use, or to be re-run through a process that includes a glass detection step.

  • What is the critical limit? No broken glass at the CCPs for glass inclusion
  • What will be monitored? The presence of broken glass on or near equipment at the CCPs
  • How is monitoring done? Visual check of the glass handling areas for broken glass
  • How often? We recommend that you check before starting operations each day, check at least every four hours during operation, check at the end of operations each day, and check whenever there is an equipment or other malfunction that could increase the likelihood that glass containers could be damaged
  • Who should perform the monitoring? Any person who has a thorough understanding of the proper condition of the glass handling equipment and surrounding area may perform monitoring. In assigning the responsibility for this monitoring function, we recommend that you consider the complexity of the equipment and the level of understanding necessary to evaluate its condition.

If broken glass is observed at a CCP, we recommend that the corrective action procedure be to stop the line, remove the broken glass, and then place on hold any product that has moved through the area where the glass breakage was observed since the last inspection, for further action as appropriate, e.g., to be run through off-line glass detection equipment, to be destroyed, to be diverted to non-food use, or to be re-run through a process that includes a glass detection step.

3.2 Metal Fragments

  • FDA recommends several possible ways to establish control measures for metal fragments in juice.

One way involves the use of on-line metal detection equipment. With this method, the equipment continuously monitors the product after the last step at which metal inclusion is reasonably likely to occur (e.g., after bottling and sealing of the juice) at a process step designated for metal detection. The critical limit might be designated as "no metal fragments in the finished product." The following illustrates some of the elements that might be entered into your HACCP plan.

    • What is the critical limit? No metal fragments in finished product (Note: FDA's Health Hazard Evaluation Board has supported regulatory action against product with glass fragments of 0.3" (7 mm) to 1.0" (25 mm) in length.
    • What will be monitored? The presence of metal fragments in containers passing the CCP.
    • How is monitoring done? By the use of metal detection equipment.
    • How often? Continuously. Each container is subjected to detection. We recommend that you confirm that the device is operating correctly at least at the start of each production day.
    • Who should perform the monitoring? Monitoring is performed by the equipment itself. We recommend that a check be made at least once per day to ensure that the device is operating correctly.

A second way to control metal fragments involves the use of a separation device such as a screen after the last step at which metal inclusion is reasonably likely to occur, at a process step designated for screening. For this approach (see example HACCP plans for Pasteurized Refrigerated Apple Juice and Not-from-concentrate Orange Juice in section VII):

    • The critical limit might be designated as "screen is functional."
    • Monitoring may be done by a daily visual check for screen integrity.
    • We recommend that verification include periodic calibration testing to ensure that the screen retains its separation capability for metal particles of a specific size. In establishing this size, we recommend that you consider that FDA's Health Hazard Evaluation Board has supported regulatory action against product with glass fragments of 0.3" (7 mm) to 1.0" (25 mm) in length. (See also FDA Compliance Policy Guide 555.425).

A third way to control metal fragments involves visually inspecting equipment for damage or missing parts at process steps such as extraction and grinding, where such damage or loss of parts could lead to metal fragments in your juice. This approach may only be feasible for relatively simple equipment that can be fully inspected visually in a reasonable time period. Under this approach, CCPs might be identified as the fruit grinding and extraction steps in a process. The critical limit might be designated as "no broken or missing metal parts from equipment at the CCPs for metal inclusion." If broken or missing metal parts are observed, the line is stopped, the equipment is repaired and, if necessary, adjusted or modified, and the product that has moved through that area since the last inspection is placed on hold for further action as appropriate, e.g., to be run through off-line metal detection equipment, to be destroyed, to be diverted to non-food use, or to be re-run through a process that includes a metal detection step. The following illustrates the elements that might be entered into your HACCP plan.

    • What is the critical limit? No broken or missing metal parts from grinding (or extraction) equipment
    • What will be monitored? The presence of broken or missing metal parts on or near the grinder
    • How is monitoring done? By visual check of the grinder and immediate vicinity for broken or missing metal parts
    • How often? Check before starting operations each day, check at least every four hours during operation, check at the end of operations each day, and check whenever there is an equipment or other malfunction that could increase the likelihood that metal inclusion could occur.
    • Who will perform the monitoring? Any person who has a thorough understanding of the proper condition of the equipment and surrounding area may perform monitoring.
    • If broken or missing metal parts are observed at a CCP, the corrective action procedure would be to stop the line, repair, adjust, and modify the equipment as necessary; the product that has moved through that area since the last inspection is placed on hold for further action as appropriate, e.g., to be run through off-line metal detection equipment, to be destroyed, to be diverted to non-food use, or to be re-run through a process that includes a metal detection step.
