3-in-1 and 4-in-1 Swab Testing

One swab, multiple tests

Environmental swabbing is a crucial microbiological process used to test food preparation surfaces, equipment, and utensils for the presence of pathogens. At Hill Labs, we continually adapt and expand our services to meet the growing demand for sustainable solutions.

Our latest innovation helps clients streamline their environmental monitoring programs by utilising both Tempo and PCR technology to test up to four organisms, using just one swab. This advancement not only saves time and effort but also reduces the use of single-use plastics, supporting both operational efficiency and environmental sustainability.

Our 3-in-1 and 4-in-1 Swab Testing:

  • simplifies sampling
  • increases efficiency 
  • reduces waste
  • is extensively validated

The 3-in-1 includes: Enterobacteriaceae enumeration, Salmonella detection and Cronobacter detection.

The 4-in-1 includes: Enterobacteriaceae enumeration, Listeria species detection, L. monocytogenes detection and Salmonella detection.
