Q

How to Control Salmonella in Fish Meal


A

Special care must be taken to prevent Salmonella infection during fishmeal production. As long as the temperature exceeds 80°C, the bacterial organic structure is destroyed during cooking and pressing, but poor hygiene conditions can lead to re-infection of fishmeal. Can lead to re-infection of fishmeal. It must be emphasized that despite the high air temperature in the dryer, the fish feed in the dryer may not be raised to a high enough temperature for long enough to destroy Salmonella. To minimize risk, manufacturers should observe the following precautions:

a. The land surrounding the factory should be properly managed and regularly maintained to prevent the entry of rodents, birds, flies and other insects. Especially in areas where fish feed is processed and fish meal is stored, very strict controls have to be exercised in this regard.

b. Fans and other vents in factories and warehouses should be protected with insect-proof and rodent-proof nets.

c. In order to keep the products dry, the warehouse should have concrete floors, leak-proof walls and roofs, and if necessary, set up roof insulation to prevent condensation and dripping of water vapor. The conveyor belt should have a cover.

d. Sidewalks leading to storage areas should be kept clean and foot pads should be provided with disinfectant. Disinfectant ingredients containing phenolic or quaternary ammonium compounds should be available to staff at the entrance to the storage area.

e. One measure that can be adopted is to implement wet and dry partitions in the plant and reduce the frequency of people and equipment passing between different areas.

f. A suitable plant cleaning program is very necessary. Empty storage bins and unloading areas should be cleaned as soon as possible after use. Processing machinery should be cleaned regularly with high pressure hot water and detergent solutions after use.

g. The protein water concentration and oil-water separation unit must be preheated to 93°C or higher before adding to the compressed fish cakes. After the machine has been running for about forty-five minutes and has been preheated to normal operating temperature, all compressed fish cakes must be returned to the cooker to be re-cooked and re-pressed to prevent re-contamination.

However, if Salmonella is detected in fishmeal, the contaminated batch must be sterilized. For example, in special units, fish meal is heated with fresh steam at high temperatures around 90°C for 10 to 15 minutes and then re-dried. Alternatively, insecticides such as formic acid and propionic acid can be used to treat infected fishmeal. Nonetheless, the reprocessing process incurs a lot of extra cost, which is much more economical if effective precautions are taken.

The fishmeal equipment can dry powder and granular materials with special requirements. In order to make the fishmeal equipment in a better state, a trial operation experiment should be carried out.

Fishmeal processing machinery is a machinery and equipment that uses fish with low economic value, fish processing waste or part of crustaceans and cephalopods as raw materials to process fishmeal. In addition to being used to produce fishmeal for feed, if the raw materials are fresh and the equipment meets hygienic conditions, it can also be used to produce edible fishmeal.
The cooking machine is the main production equipment for the processing of fish meal equipment. It is indirectly heated by steam or heat-conducting oil to ensure that the raw fish is well-proportioned and cooked.
How is fish meal processed 2022-05-27 11:37:42.877
Fish meal is a feed additive. The purpose of fishmeal production is to destroy cell tissue, dissolve oil, kill microorganisms, inhibit the action of enzymes, remove water, reduce body weight and weight, prevent the reproduction of microorganisms, and is conducive to preservation and utilization.
Fishmeal and Fish Oil Production Process 2022-05-27 11:35:49.114
The processing of raw materials for fishmeal and fish oil production basically follows a cycle of cooking, processing, extraction and drying. While producing fishmeal and fish oil, only steam is formed as a by-product. In fact, the product contains all the raw materials, but does not include most of the moisture in it. Processing follows strict quality management procedures to ensure that final product parameters meet confirmed nutrient and contaminant range requirements. This process is very technically demanding in order to preserve the nutrient content of the raw materials as much as possible and to ensure the successful transfer of these components to the final fishmeal and fish oil products.

The role of fish meal in animal feed 2022-05-27 11:34:42.551
Fishmeal can be used as feed for poultry, pigs, ruminants, farmed fish and fur-producing animals. It increases yields and increases the efficiency of converting feed into animal products (feed conversion ratio). It has special value in the feed of young animals. For example, in broiler feeds, in pig feeds during weaning, and in farmed fish and fur-producing animal feeds.
How to add antioxidants to fish meal? 2022-05-27 11:33:59.410
Fishmeal is a natural product that contains fish oil and therefore also high amounts of omega-3 fatty acids
According to our understanding, fish meal is a high-protein feed material that uses one or more kinds of fish as raw materials, and is processed by oil removal, dehydration, and crushing. Domestic fish meal protein is more than 55%; it does not contain indigestible substances such as cellulose, has high crude fat content, and has a high effective energy value; rich in B vitamins, calcium, phosphorus, iodine, zinc, iron, selenium content It is very high and the proportion is appropriate. All phosphorus is available phosphorus and is an important source of minerals in the process of animal growth and development; fish meal also contains an unknown factor that can promote animal growth and development. Fish oil contains triglycerides, phosphoglycerides, lipids, fat-soluble vitamins, protein degradation products, etc., and is also rich in n-3 polyunsaturated fatty acids, which integrates nutrition, palatability and functionality. Nutritional feed, if fish oil is put into animal feed, it can also help animals grow and develop.
