CONTAINER, CAP AND CLOSURE COMPANIES

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.

CONTAINER, CAP AND CLOSURE COMPANIES

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.

Daily Laboratories is a 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.

PRODUCE, SPICES, FOOD

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.

DAIRY INDUSTRY

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 15 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:

MEAT PROCESSING AND PACKING INDUSTRY

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.

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 supplies.  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.

 

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

 

We can test any water sample for Total  Coliform, Total Bacteria, Total Yeast & Mold and E. coli. We are certified for potability testing for new construction.
