Surface Sampling Solutions
The environment is a principal source of microbiological contamination within a food processing facility. At the same time, in livestock farming, the environment can indicate whether a farm safety program is functioning as it should. Environmental testing has therefore become a crucial part of any food and feed safety program.
Romer Labs offers a broad range of easy-to-use, sterile specimen collection and surface sampling kits for quality control and identification of hazards at critical control points.

Cellulose Sponges for Food Production Applications
Dry and pre-moistened sterile cellulose sponges are convenient, ready-to-use products. They eliminate the costly and time-consuming steps of diluent preparation, sterilization and application to the sampling devices. They are designed to make sampling microbes from surfaces in food processing facilities and industrial settings more convenient. Sterility is guaranteed by exposing sampling products to irradiation. The use of different pre-moistening solutions enables a broad range of environmental and product (carcass) sampling applications.

Sponge-Sticks
The Romer Labs Sponge-Stick is a 3″ x 1.5″ (7.5 cm x 3.5 cm) compressed cellulose sponge attached to a quick-release handle, pre-moistened with 10 ml buffer of choice and individually packaged in a vapor-barrier foil pouch or already in a sampling bag. The quick-release handle provides an extra level of convenience and reliability. It is designed to release the sponge into the sample bag after sample collection, allowing only the sponge to be returned to the laboratory. Unnecessary parts that could interfere with sample processing are therefore eliminated.
The product is available in three versions:
- Sponge-Stick in vapor-barrier aluminum foil pouch for long shelf life with 2 years from production (includes also sterile twirl-tie bag; 24 oz 5.5" x 9")
- Sponge-Stick placed in twirl-tie bag with 12 months shelf life from production
- Sponge-Stick with dry sponge placed in twirl-tie bag with 5 years shelf life from production

Environmental Sampling for Livestock Farming Applications
Salmonella and Campylobacter contamination of poultry and other livestock products is a worldwide concern. To reduce instances of contamination at farms, methods for monitoring Salmonella and Campylobacter contamination in livestock shelters, beginning with drag swab sampling, have been developed by the USDA-FSIS (Food Safety Inspection Service).
Alternative boot swabs are also used as stated in various EU regulations (e.g. Regulation of the Commission No. 2160/2003, 213/2009, 200/2010, 517/2011, 200/2012 and 1190/2012) to meet this objective.
Drag swab kits are sterile sampling devices used to sample poultry litter for pathogenic organisms such as Salmonella.
