For example, a method may include providing at least one aggregating sampler at one or more sampling locations, and sampling a production lot of produce or other food items such as meat using the at least one aggregating sampler to create one or more samples that makes up a microbial sampling. Certain aspects of the present disclosure relate to methods and apparatus for microbial sampling of foods. For example, an apparatus, such as a microbial aggregating sampler, may include a covering having a microbial sampling material with a pocket formed in the covering to receive an appendage or a tool for handling of the covering.

Sampling probe devices and methods for sampling frozen or solid meltable products are provided herein. Such devices can include a sampling probe with heating element and a cover fabricated at least partly from a microbial sampling medium that fits over the probe and heating element so that when the heated probe is placed against the frozen or solid product, the cover absorbs a liquid sample from the product. Methods of sampling include heating the probe and contacting the product with the cover until sufficient liquid sample is absorbed by the cover. The cover can be weighed after sampling and compared to a before-sampling weight to confirm sufficient liquid was obtained. The sample can be tested as an aggregate sample that is representative of the lot or batch of product being sampled, including testing without an enrichment procedure. Systems utilizing automated heated-sampling plates and radiative heaters are also described.

The invention discloses a preparation method of a composite membrane used for sampling and detecting microorganisms in the air. Place the supporting porous membrane on a horizontal glass plate, adjust the height of the membrane-making knife, and move the knife holder at a speed of 5-6 cm per minute, so that the membrane-making liquid is evenly distributed on the surface of the porous membrane to form a composite membrane skin layer, and the reaction temperature is 20 ~30℃, humidity 20~50%, pressure is negative pressure below atmospheric pressure, then heat treatment at 40~80℃ for 1~3 hours, and at the same time, composite membranes with different pore sizes can be prepared by adjusting the concentration of chitosan membrane-making liquid . The macromolecular substances in the composite membrane can maintain the activity of the entrapped microorganisms to a certain extent. Compared with other filter membranes, the composite membrane can reduce the formation of filter cake, and the flux is significantly increased compared with other filter membranes with the same pore size under the same test conditions. At the same time, the macromolecule coating solution used has biological activity, which can help microorganisms to maintain activity to a certain extent, so that the sample can reflect the air condition more realistically, and it also improves the problem of microbial activity maintenance during microbial sampling and reduces detection errors.

A method of making sampling tubes containing culture growth media by loading the sample tubes containing culture media into a tray that holds the sample tubes, placing the sample tube trays into a rack with shelving to hold the trays and tubes at a predetermined angle, and sterilizing and cooling the sample tubes in an autoclave or inspissator. The culture growth media solidifies at the predetermined slant angle and the sample tube trays are loaded into the packaging box used for shipment. The trays are subsequently used by the end user for processing microbial growth, including storing and collecting data about microbial samples.

Aspects of the present invention provide novel apparatus and methods for sampling microbial organisms present on surfaces. Preferred apparatus comprises: a reservoir suitable for providing microbial collection fluid; a sterilizable sample collection chamber; a sterilizable, integrated collection fluid delivery and collection fluid recovery member, suitable to deliver collection fluid to a target surface, and contemporaneously recover the delivered fluid from the surface; delivery means, in communication with both the reservoir and the integrated member, and operable to aseptically deliver collection fluid from the reservoir to the integrated member; and vacuum means, in communication with both the sample collection chamber and the integrated member, and operable to direct collection fluid, delivered and recovered by the integrated member, to the sample collection chamber. Additional aspects provide a method for rapid, high-throughput sampling of microbial organisms present on surfaces, comprising: delivering sample collection fluid to a target surface, and contemporaneously recovering the delivered fluid from the target surface by means of an integrated collection fluid delivery and collection fluid recovery member; and collecting the recovered sample collection fluid into a sample collection chamber in communication with the integrated member, whereby sample collection is, at least in part, achieved. The inventive methods and apparatus can be applied to both surface sampling and to atmospheric sampling.

The invention discloses a device for extracting intestinal microorganisms in animal bodies, and relates to the technical field of microorganism sampling, the device comprises an extraction seat, first mounting racks are fixedly mounted at the edge of the top of the extraction seat, rotating rods are rotatably connected to the side surfaces of the first mounting racks, and the first mounting racks are symmetrically arranged at the two ends of the rotating rods; and one end of the rotating rod penetrates through the outer wall of the first mounting frame, and a placement frame is fixedly mounted on the outer wall of the extraction seat.

The present invention relates to a sterile sampling valve used on production pipelines or tanks for fizzy drinks, such as beer, cola, fruit milk, etc in order to solve the technical problems existing in the prior art that the sterilization and the oxygen isolation of valve cavities can not be ensured as the sampling valves used food industry are always exposed in the air, the cleaning operation is complicated, etc. The sampling valve comprises a sampling valve body and a sampling valve jacket. The sampling valve body is movably sheathed in the valve jacket. The valve jacket is divided into anupper cavity and a lower cavity by the valve body, wherein the lower cavity is sealed, and the upper cavity is open. As the sampling valve body is arranged in the valve jacket rather than directly exposed in the external environment, samples taken are effectively protected from pollution. Besides, the immersion of the sampling valve body in a sterilizing agent performs the double functions of sterilization and oxygen isolation. The sterilization operating steps for the valve body can be simplified during sampling, and the microbe sampling efficiency is improved. Even though the valve is not thoroughly cleaned after sampling, the sterile state of the valve body can still be well ensured.
