16. Safety and consistency
Control Program Requirements for Fermented Meat Products
The producer must have a program in place to assess the incoming product. This program should outline specifications for the incoming ingredients. This may include criteria including receiving temperature, farm/ supplier, lot code or packed on date, species/cut etc.
2. Facility and Equipment Requirements
Equipment used in the fermentation process must be included in the operator's prerequisite control programs. These must include the following elements:
Temperature in the fermentation, drying and smoking chambers must be uniform and controlled to prevent any fluctuation that could impact on the safety of the final product.
Fermentation, drying and smoking chambers must be equipped with a shatter resistant indicating thermometer, (or equivalent), with graduations of 1°C or less. If mercury thermometers are used, their mercury columns must be free from separations. All thermometers must be located such that they can be easily read.
Fermentation and smoking chambers must be equipped with a recording thermometer for determining degree-hours calculations in a reliable manner. Recording thermometers are also preferable in drying and aging rooms but, in these rooms, it may be sufficient to read and record the temperatures 2 times a day.
Drying and aging rooms must be equipped with humidity recorders in order to prevent uncontrolled fluctuations of the relative humidity. The only alternative to an automatic humidity recorder in these rooms would be for the company to manually monitor and record ambient humidity twice a day (morning and afternoon) every day with a properly calibrated portable humidity recorder.
For routine monitoring, accurate measurement electronic pH meters (± 0.05 units) should be employed. It is important that the manufacturer's instructions for use, maintenance and calibration of the instrument as well as recommended sample preparation and testing be followed.
When the aw of a product is a critical limit set out in the HACCP plan for a meat product, accurate measurement devices must be employed. It is important that the manufacturer's instructions for use, maintenance and calibration of the instrument be followed.
3. Starter Culture
The operator must use a CFIA approved starter culture. This includes Freeze-dried commercially available culture as well as back-slopping (use of previously successful fermented meat used to inoculate a new batch). When performing back-slopping, the operator must have a control program in place to prevent the transmission of pathogens from when using the inoculum from a previous batch to initiate the fermentation process of a new batch. These must include:
The storage temperature must be maintained at 4°C or less and a pH of 5.3 or less.
Samples for microbiological analysis must be taken to ensure that the process is in line with the specifications.
The frequency of sampling is to be adjusted according to compliance to specifications.
Any batch of inoculum which has a pH greater than 5.3 must be analysed to detect at least Staphylococcus aureus. Only upon satisfactory results will this inoculum be permitted for use in back slopping.
This can be an expensive and a time exhaustive process and is generally avoided due to food safety concerns. AHS does not allow back-slopping.
[Chef WK was in communication with the U of A to get his method, a starter mix, studied.]
4. Chemical Acidification
If product is chemically acidified by addition of citric acid, glucono-delta-lactone or another chemical agent approved for this purpose, controls must be in place and records kept to ensure that a pH of 5.3 or lower is achieved by the end of the fermentation process. These acids are encapsulated in different coatings that melt at specific temperatures, which then release the powdered acids into the meat batter and directly chemically acidulate the protein.
Summer sausage is a very common chemically acidified product. The flavor profile tends to be monotone and lacking depth.
5. Water Activity Critical Limits
The aw may be reduced by adding solutes (salt, sugar) or removing moisture.
Approximate minimum levels of aw (if considered alone) for the growth of:
molds: 0.61 to 0.96
yeasts: 0.62 to 0.90
bacteria: 0.86 to 0.97
Clostridium botulinum: 0.95 to 0.97
Clostridium perfringens: 0.95
Enterobacteriaceae: 0.94 to 0.97
Pseudomonas fluorescens: 0.97
Salmonella: 0.92 - 0.95
Staphylococcus aureus: 0.86
parasites: Trichinella spiralis will survive at an aw of 0.93 but is destroyed at an aw of 0.85 or less.
The above levels are based on the absence of other inhibitory effects such as nitrite, competitive growth, sub-optimum temperatures, etc., which may be present in meat products. In normal conditions, Staphylococcus aureus enterotoxins are not produced below aw 0.86, although in vacuum packed products this is unlikely below aw 0.89.
6. Time and Temperature for Fermented Products
Certain strains of the bacteria Staphylococcus aureus are capable of producing a highly heat stable toxin that causes illness in humans. Above a critical temperature of 15.6°C, Staphylococcus aureus multiplication and toxin production can take place. Once a pH of 5.3 is reached, Staphylococcus aureus multiplication and toxin production are stopped.
Degree-hours are the product of time as measured in hours at a particular temperature multiplied by the "degrees" measured in excess of 15.6°C (the critical temperature for growth of Staphylococcus aureus). Degree-hours are calculated for each temperature used in the process. The limitation of the number of degree-hours depends upon the highest temperature in the fermentation process prior to the time that a pH of 5.3 or less is attained.
The operator is encouraged to measure temperatures at the surface of the product. Where this is not possible, the operator should utilize fermentation room temperatures. The degree hour calculations are based on fermentation room temperatures. Temperature and humidity should be uniform throughout the fermentation room.
A process can be judged as acceptable provided the product consistently reaches a pH of 5.3 using:
fewer than 665 degree-hours when the highest fermentation temperature is less than 33°C;
fewer than 555 degree-hours when the highest fermentation temperature is between 33° and 37°C; and
fewer than 500 degree-hours when the highest fermentation temperature is greater than 37°C.
This means that as the temperature increases, the amount of time that you have available to reach 5.3 or under is shorter. The warmer the temperature, the sharper the log growth phase of bacteria, which equates to more overshoot in lactic acid production, faster.
8. Examples of Degree-hours at constant room temperatures
Example 1:
Fermentation room temperature is a constant 26°C. It takes 55 hours for the pH to reach 5.3.
Degrees above 15.6°C: 26°C - 15.6°C = 10.4°C
Hours to reach pH of 5.3: 55
Degree-hours calculation: (10.4°C) x (55) = 572 degree-hours
The corresponding degree-hours limit (less than 33°C) is 665 degree-hours.
Conclusion: Example 1 meets the guideline because its degree-hours are less than the limit.
Example 2:
Fermentation room temperature is a constant 35°C. It takes 40 hours for the pH to reach 5.3.
Degrees above 15.6°C: 35°C - 15.6°C = 19.4°C
Hours to reach pH of 5.3: 40
Degree-hours calculation: (19.4°C) x (40) = 776 degree-hours
The corresponding degree-hours limit (between 33 and 37°C) is 555 degree-hours.
Conclusion: Example 2 does not meet the guideline because its degree-hours exceed the limit
9. Fermentation Done at Different Temperatures
When the fermentation takes place at various temperatures, each temperature step in the process is analyzed for the number of degree-hours it contributes. The degree-hours limit for the entire fermentation process is based on the highest temperature reached during fermentation.
Example 1:
It takes 35 hours for product to reach a pH of 5.3 or less. Fermentation room temperature is 24°C for the first 10 hours, 30°C for second 10 hours and 35°C for the final 15 hours.
Step 1
Degrees above 15.6°C: 24°C - 15.6°C = 8.4°C
Hours to reach pH of 5.3: 10
Degree-hours calculation: (8.4°C) x (10) = 84 degree-hours
Step 2
Degrees above 15.6°C: 30°C - 15.6°C = 14.4°C
Hours to reach pH of 5.3: 10
Degree-hours calculation: (14.4°C) x (10) = 144 degree-hours
Step 3
Degrees above 15.6°C: 35°C - 15.6°C = 19.4°C
Hours to reach pH of 5.3: 15
Degree-hours calculation: (19.4°C) x (15) = 291 degree-hours
Degree-hours calculation for the entire fermentation process = 84 + 144 + 291 = 519
The highest temperature reached = 35°C
The corresponding degree-hour limit = 555 (between 33°C and 37°C)Conclusion: Example 1 meets the guideline because its degree-hours are less than the limit.
10. Fermentation done at Different temperatures
Example 2:
It takes 38 hours for product to reach a pH of 5.3 or less. Fermentation room temperature is 24°C for the first 10 hours, 30°C for the second 10 hours and 37°C for the final 18 hours.
Step 1
Degrees above 15.6°C: 24°C - 15.6°C = 8.4°C
Hours to reach pH of 5.3: 10
Degree-hours calculation: (8.4°C) x (10) = 84 degree-hours
Step 2
Degrees above 15.6°C: 30°C - 15.6°C = 14.4°C
Hours to reach pH of 5.3: 10
Degree-hours calculation: (14.4°C) x (10) = 144 degree-hours
Step 3
Degrees above 15.6°C: 37°C - 15.6°C = 21.4°C
Hours to reach pH of 5.3: 18
Degree-hours calculation: (21.4°C) x (18) = 385.2 degree-hours
Degree-hours calculation for the entire fermentation process = 84 + 144 + 385.2 = 613.2
The highest temperature reached = 37°C
The corresponding degree-hour limit = 555 (between 33°C and 37°C)
Conclusion: Example 2 does not meet the guidelines because its degree-hours exceed the limit.
11. What happens if fermentation fails to hit critical limit?
What happens if the batch takes longer than degree-hours allows? For restaurant level production, it's always safer to discard the product. The toxin that Staph. Aureus produces is heat stable and cannot be cooked to deactivate. In large facilities that produce substantial batches, the operator must notify the CFIA of each case where degree-hours limits have been exceeded. Such lots must be held and samples of product submitted for microbiological laboratory examination after the drying period has been completed. Analyses should be done for Staphylococcus aureus and its enterotoxin, and for principal pathogens, such as E. coli O157:H7, Salmonella, and Clostridium botulinum and Listeria monocytogenes.
If the bacteriological evaluation proves that there are fewer than 104 Staphylococcus aureus per gram and that no enterotoxin or other pathogens are detected, then the product may be sold provided that it is labelled as requiring refrigeration.
In the case of a Staphylococcus aureus level higher than 104 per gram with no enterotoxin present the product may be used in the production of a cooked product but only if the heating process achieves full lethality applicable to the meat product.
In the case where Staphylococcus aureus enterotoxin is detected in the product the product must be destroyed.
12. E. coli and Salmonella Control in Fermented Sausages
Business' that manufacture fermented sausages are required to control for verotoxinogenic E. coli including E. coli O157:H7 and Salmonella when they make this type of product. This includes:
establishments which use beef as an ingredient in a dry or semi-dry fermented meat sausage;
establishments which store or handle uncooked beef on site;
Establishments which do not use beef and do not obtain meat ingredients from establishments which handle beef are not currently required to use one of the five options for the control of E. coli O157:H7 in dry/semi-dry fermented sausages.
Any processed RTE product containing beef or processed in a facility that also processed beef, must be subjected to a heat treatment step to control E. coli O157:H7. Heating to an internal temperature of 71°C for 15 seconds or other treatment to achieve a 5D reduction is necessary. This is a CFIA requirement and is not negotiable.
Uncooked air dried products produced as RTE, must meet shelf stable requirements as detailed for Fermented-Dry products.
13. Options for E. coli validation
Without lab testing, the two main methods of validation are with heat treating by either low temp and a long duration, or various hotter processing temperatures for a shorter timeframe.
A challenge study to validate a process can take 1 year and over $100,000!
14. Option1; Heating
15. Option 2; pH, heating, holding, diameter
16. Safety and consistency
The aw and pH values are critical in the control of pathogens as well as to ensure shelf-stability in all semi-dry and dry fermented meat products. Each batch must be tested for aw and/or pH in order to verify that the critical limits are met.
Although aw measurement is mandatory only for shelf stable products, it is strongly recommended that the producer determine the aw values achieved for each product type they manufacture and for each product. Once this has been established, frequent regular checks should be made to ensure consistency. In the U.S., they rely on moisture to protein ratio and have set targets. This lab-tested value is a direct correlation of the % water to % meat protein and not aw. This gives more consistency to common names. For example, to legally call a product "jerky" it must have a MPR of 0.75:1 or lower.
Remember your ABCs:
Always be compliant.

Some Basic Structures of Fast Blue Impeller Paddle Wheel Aerator
Fast Blue Impeller Paddle Wheel Aerator utilizes a straightforward yet highly effective mechanism to enhance water quality and oxygen levels within aquaculture systems. The aerator is equipped with an impeller, driven by an electric motor, that rotates within the water. The impeller blades create a vigorous water movement, resulting in several critical effects:
Oxygenation: The primary objective of the Fast Blue Impeller Paddle Wheel Aerator is to elevate the dissolved oxygen levels in the water. As the impeller blades agitate and disperse water, they facilitate increased oxygen exchange between the air and the aquatic organisms. Adequate oxygen levels are paramount for the respiration and overall health of fish and other aquatic species.
Temperature Control: Continuous water circulation helps maintain a consistent temperature throughout the aquaculture environment, preventing the formation of harmful temperature gradients that could endanger aquatic life.
Nutrient Dispersal: The aerator ensures that essential nutrients and feed are evenly distributed throughout the pond, promoting uniform growth and minimizing resource wastage.
