Some of the industries we work with are 

Containers & Closures – Municipal Water Departments – Dairies – Meat Processors – Produce Distributors – Snack Food Producers – Spices – OTC Pharmaceuticals – Realtors – Well Inspectors – New Plumbing Construction – Small Farms – Pet Foods. Really any food plant with regulations.


Single-service containers and closures have been used in the dairy industry for many years. Evaluation of the industry’s basic manufacturing and handling techniques and establishment of sanitation criteria assure the containers and closures and the materials they are made from are safe and in compliance with FDA-established bacteriological standards.


These standards apply to bottles by pre-formed bottle manufacturers, blow-molders, vacuum formers, plastic extruders and injection molders. Closure manufacturers include plastic screw and plug caps. These standards also apply to fabricating plants that produce a component part which may become a product-contact surface such as film, linings or foils.


Examples of some products the standards apply include milk jugs, the cap on the milk jug, the liner material in the cap, foil on the yogurt cup, grated cheese containers, individual creamers, to name a few. The same standards can be used for water bottles and closures, disposable cups, plasticware and straws.


Daily Laboratories is a NCIMS certified approved laboratory and performs the standards testing for residual bacteria counts and residual coliform counts for the container, cap and closure industry routinely. We can also test for the presence of yeast and molds.  The process waters and silicone blends can be tested and monitored as well.


Daily Laboratories offers a range of testing services for the food industry.   Routine microbiological analyses include

  • Total Bacterial Counts
  • Total Yeast and Mold Counts
  • Enterobacteriaceae
  • Coliform and E. coli Counts
  • Bacillus cereus


Specific pathogens we can test for include Listeria spp, E. coli 0157:H7, and Salmonella spp.    We can help food processors monitor their plant’s environment for pathogens and carry-over allergens after cleaning. 

Spices and foods can be tested for Water activity and pH to assist shelf stability.

Produce and the wash water can be tested for pesticide residue. 

We can also test ice from ice machines for sanitation and cleanliness.


Daily Laboratories was originally established in 1960 as a dairy laboratory in Peoria, IL by Howard Daily at the request of the Illinois Dept. of Public Health. We currently meet the following requirements:

  • Illinois Department of Public Health
  • Interstate Milk Shippers Program
  • Grade A Pasteurized Milk Ordinance
  • Food and Drug Administration

Daily Laboratories perform microbiological testing on raw cow and goat milk, milk products, and dairy products including cheese and ice cream. We monitor raw milk for the presence of inhibitors (antibiotics). We also do component testing of raw milk.

Daily Laboratories is a state-approved testing laboratory for raw milk to be sold from the farm.

Monitoring dairy plants for pathogens, such as Listeria and Salmonella has been a concern for the past 35 years and Daily Laboratories has programs with dairies to monitor their environmental pathogens. 

Below, find some of the analyses we currently perform on dairy products:



Aerobic Plate Count 
DMSCC – cow 
DMSCC – goat 
E. coli Density
Yeast & mold counts 
Antibiotic residue
Environmental samples for Listeria spp.
Environmental samples for Salmonella spp.




Solids, not fat (SNF) 


Added water





Daily Laboratories tests meat products for microbiological quality. This includes indicator organisms, as well as pathogens. We test carcass samples and rinses, ground meat, raw trim N-60 samples, raw finished products and cooked product. We also work with meat processors to monitor their plant’s environments for Listeria sp. and Salmonella sp.


Analyses for the meat industry includes:


  • E. coli detection – generic
  • E. coli 0157:H7
  • Listeria spp.
  • Salmonella spp.


Environmental samples for Listeria spp., Salmonella spp. and coliform

Finished products, such as jerky, can be tested for pH and Water Activity for shelf stability.

All of the analyses are done with AOAC certified and USDA approved methods.


Daily Laboratories does microbial analysis on raw materials or ingredients as well as finished products, such as lotions, creams and capsules. We can also test the plant and USP waters. 

FDA required analyses may include:

  • aerobic plate count / total bacterial count
  • yeast & mold count
  • Staphylococcus aureus
  • Pseudomonas aeruginosa
  • Salmonella sp. 
  • Total coliform

Daily Laboratories is registered on the FDA Drug Establishments database. 



Municipal Water Companies 

Bacteriological Water Quality testing per SM 9020 Quality Assurance Guidelines 

Laboratories performing microbiological testing are required to annually document the suitability of their reagent water in order to fulfill QA/QC requirements for accrediting bodies.

Daily Laboratories is one of the few laboratories that perform the microbial water suitability test on a weekly basis for municipal water suppliers.  This test is listed on the EPA laboratory evaluation form as laboratory pure water bacteriological quality or ratio of growth rate.  This test is required at least annually by the EPA and state health departments for water laboratories as part of the intralaboratory quality control practices. The test is complex, requires skill and experience, and is not easily done on an infrequent basis. It requires work over 4 days, an independent ultrapure water, high purity reagents, and aseptic technique. The test is very sensitive to toxic agents or growth-promoting substances.

We can also perform the use test, depending on your state’s requirements.

Realtors – Well Inspectors – New Construction

For home sales involving rural property with a well, most lending institutions will require that the well pass a water quality test prior to loan approval. They will require testing of the well water for bacteria, nitrate and nitrite at a minimum. Some may require testing for lead leaching from old water lines.  We can test those well waters for home sales.

Testing is normally completed in 24 hours. 

We are certified for potability testing for new construction.
