Delvotest®: A Gold Standard

Forty years ago, DSM introduced Delvotest®, an easy to use, reliable, antibiotic residue test for farmers, dairies, and milk control laboratories. Today, Delvotest® is the gold standard for antibiotic residue testing in the global dairy industry, since it provides the confidence to meet increasingly stringent global legislation and quality demands.

When it comes to individuals daily food consumption, the last thing we seem to worry about is the presence of antibiotic residue in our meats or dairy products. But if a dairy cow had an antibiotic in its system that was designed to fight off a bacterial infection, the residue from the antibiotic could easily be carried over to the milk the cow produced, which is not good. If the entire tank truck of milk was contaminated with antibiotics, the whole thing must be discarded per the FDA.

Delvotest® detects the broadest spectrum of antibiotic residues in every kind of milk—cow, sheep, goat, buffalo—as well as in dairy products. Depending on the antibiotic used, the withdrawal period could be as short as 1 or 2 days, or as long as a few weeks. This is why it is important to utilize test kits to track the withdrawal period. Delvotest® is known for its reliability and accuracy with detection levels closest to Maximum Residue Levels and Safe Tolerance Levels (US). Therefore, Delvotest® is chosen as the national reference test in most countries worldwide. Delvotest® test kits cover three different market areas. Click on the link(s) below that is most suitable for your needs to see which kit is right for you!

Artisan/Farmstead
Kits are designed for artisan and farmstead cheese and dairy processing applications. Delvotest® confidently detects the broadest spectrum of antibiotics in milk and meets the required antibiotic testing requirements for every state in the U.S. Delvotest® is approved by the National Conference on Interstate Milk Shipments (NCIMS) for the testing of bovine, goat, and water buffalo milk.

Dairy Farmer
These antibiotic residue tests eliminate the uncertainties dairy farmers face when testing for antibiotics in milk. Whether you are testing a bulk tank, or an individual bovine, sheep, goat or buffalo, the consequences of an unreliable test can be costly and devastating. Compared to other antibiotic residue tests on the market, Delvotest® provides low initial start-up costs.

Certified Dairy Laboratory
Enables certified laboratories the ability to reach maximum throughput in milk testing for antibiotic residues. For over 40 years, Delvotest® has enabled dairy laboratories to service the dairy industry with high-quality control over the entire milk supply chain. Dairy laboratories aim to assure that milk quality meets legal quality standards so the test systems they rely on must be robust, accurate and efficient. Delvotest® has become the global standard in antibiotic residue testing due to its consistency, reliability, accuracy and performance. It reduces the time and costs associated with large scale antibiotic residue testing.

Whether you’re a dairy processor or farmer, its essential to avoid passing antibiotic-contaminated milk into the supply stream. These uncertainties are crucial to overcome because it can be both costly and devastating to your company.  No matter where you stand in the milk industry, when you buy into Delvotest® you are buying not only reliable equipment, but also over 40 years of experience and expertise in the milk testing industry.

“Eek-osystems”: Biofilm Considerations for the Food Industry

Have you ever missed one or two of your normal tooth-brushing sessions, and found your tongue traversing over a disconcertingly slimy layer coating your chompers?   Well, welcome to the disturbing and quite fascinating world of biofilms.  These hearty amalgams of microbiological activity provide both protection for microorganisms, as well as headaches for not only those avoiding plaque build-up, but most importantly for this blog, the food industry (allowing harborage and protection for bacteria and fungi).

Biofilms can form on a variety of surfaces in food processing environments, including stainless steel.  A supercell of harborage, “Biofilms are complex microbial ecosystems formed by one or more species immersed in an extracellular matrix of different compositions depending on the type of food manufacturing environment and the colonizing species” (Geaile, et al).   The “matrix” formed creates a powerful source of protection and fuel for the continued life and shear tenacity of these “eek-osystems”  to affect, disrupt, and harm products.     

Though biofilms are capable of creating a lot of hassle when it comes to cleaning, spoilage concerns, etc., Gaile, et al, in  “Biofilms in the Food Industry: Health Aspects and Control Methods” note:  “Of particular importance to the food industry is that some biofilm-forming species in food factory environments are human pathogens.”  With biofilms aiding and abetting pathogens, the cost of not waging an effective sanitation onslaught, may create food safety issues of serious proportions.   This is even further complicated by the fact that, “Mixed biofilms show higher resistance to disinfectants such as quaternary ammonium compounds and other biocides” (Gealie, et al.).   This means traditional cleaning protocols may not be enough to counter the threat biofilms pose to public health.

Here at Nelson-Jameson, we continue to work with our supplier-partners to take on the threat of biofilms in the food industry.   Our hope is that through a multi-pronged approach, we can help address this serious concern for our customers.  Here are just a few of the ways we are taking on the challenges of biofilms currently:

  1. Providing effective and efficient cleaning solutions, like hygienic brushes and squeegees from Remco and Carlisle, to cleaning chemical options from Hydrite, Kersia, and Best Sanitizers.  
  2.  Formulating and offering the best enzymatic cleaning solutions with Realzyme.
  3. Offering the best in testing solutions, including 3M Petrifilm and ATP testing equipment, as well as offering sampling collection/sample integrity products from Whirl-Pak and QualiTru.   

Though continuing to be a tough challenge for the food industry, biofilms will squarely be in the crosshairs of our team and our supplier partners.  Together, across the industry, we can seek out effective solutions, and build tailored programs to take on the challenge and the tenacity of biofilms in the production environment.   For an excellent resource on biofilms please be sure to consult the Gealie et al. article referenced above, here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5949339/.

Tips on Preventing Food Contamination This Fourth of July

Summer is here! What a perfect opportunity to get outside and enjoy the warm summer air we’ve all been craving! For some individuals, spending time outdoors could involve hiking, boating, or reading in the shade, but one thing we can all agree on, summer is the perfect time to enjoy some of our favorite foods on the grill. Whether with family, friends, or even coworkers, cooking food on the grill appears to be a popular summer activity. With summer holidays approaching, like the Fourth of July, it is important to keep your celebrations healthy and safe by following food safety tips to prevent contamination while grilling.

According to the FDA and the USDA Food Safety organizations, there are grilling food safety tips to be followed for all food types:

  • Be Clean: First, make sure to wash your hands thoroughly, especially after touching any form of raw meat. Before consumption, make sure to rinse off fruits and vegetables as there may be bacteria on the surfaces. Never rinse off raw meat as this can increase your risk of cross-contamination.
  • Separate: Keep raw meats away from other foods such as salads, dips, or fruit. Be conscientious of not using the same utensils for putting raw meat on the grill, and for taking cooked meat off the grill. Using the same utensils that touched raw meat could be covered in harmful bacteria, which can contaminate the cooked meat.
  • Temperature: Use a food thermometer to check if food is fully cooked. Sometimes grilling can give you a false impression where food looks fully cooked on the outside, but is under cooked on the inside. The recommended internal temperature for beef, pork, lamb, and veal is 145°F, ground meat is 160°F, whole poultry is 165°F, and fish is 145°F.
  • Fruits and Vegetables: Lastly, make sure to be aware of how long fruits and vegetables should be cooking on the grill. Thicker cut fruits and vegetables will have to cook longer than thinner pieces. Although, fruits and vegetables do not have to reach a minimum internal temperature like meat, it is still important to cook them thoroughly.

Although grilling out in the summer can be a fun thing to do, it is important to take action and be careful in preventing the harmful spread of bacteria to our food. To learn more about additional tips and guidelines to follow when cooking various foods this summer, check out the FDA and USDA Food Safety organization websites to learn more.

Metal Detectable Products: A Critical Component in Food Safety

A critical component in food safety is the detection of contaminants. One of the worst nightmares of anyone working in food processing, is finding something in the final product that is not supposed to be there. This can cause costly product loss, clean-up and maintenance costs, and the potential for recalls and/or litigation. Even though everyone tries to prevent foreign object contamination, pieces of tools such as scrapers can break off, or items such as pens can fall into the product. To make sure that these items are caught, and that contaminated product does not make it out the door, many plants utilize metal detection devices and products.

Metal detectable products are constructed of a few different materials. They are often blue for easy visual detection. Blue is also the most common non-food color. Metal detectable products are made through a unique manufacturing process that involves the inclusion of a metallic pigment. This enables the plastic to be detected. In some objects such as earplugs, a stainless steel ball bearing is enclosed in the plug, making them detectable. A product with embedded metal is only detectable if the product piece containing the metal goes through a detector. With a product that is impregnated, the entire piece has fine metal particles throughout, making the entire piece, or parts of it, detectable.

Metal detectable calibration is an important aspect of a metal detectable program. To maintain calibration, you should periodically check calibration by passing a known calibration test tool under the unit to check for accuracy. Test tools can be made of ferrous, non-ferrous, or stainless steel and include rods, cylinders, balls, whips, cards, and more. Depending on the food being produced, machine calibration must be adjusted and set to a threshold that is determined by the company in regards to the size of contaminant they want the detector to reject. Many things affect the setting of the machine including whether the food is wet or dry, its size, and its speed. If you don’t test your calibration, the metal detector can allow larger pieces of foreign object contaminant to get through than the threshold setting, which threatens the finished product’s safety. 

Nelson-Jameson can help you start or expand your Metal Detectable program with our wide range of products. Our new Metal Detectable Flyer features 32 pages of products ranging from writing utensils and office supplies to calibration tools and scrapers. We also have metal detection and x-ray equipment from Valcour Process Technologies to help enhance your program. Request your free copy of our flyer, or visit our website to download it today!

Celebrating World Food Safety Day!

Food safety truly is a collective effort. From the farm to the table, ensuring food safety is a way we can reaffirm our investment in, and care of, those we are feeding. Whether you are helping in the harvest, producing and processing thousands of products a day, serving food at a local pub, or grilling for your family, food safety requires vigilance and care at all levels. Keeping this in mind, the World Health Organization, in collaboration with the Food and Agricultural Organization of the United Nations, are recognizing all of those interconnecting players with World Food Safety Day on June 7th.   

The celebration of World Food Safety Day is meant “to draw attention and inspire action to help prevent, detect and manage foodborne risks, contributing to food security, human health, economic prosperity, agriculture, market access, tourism and sustainable development.” When one considers how food plays into all of these areas, and reverberates across everyday life, food safety really does bind us all together.  

….and there is work to do. Though we are incredibly fortunate to have a robust and generally safe food supply, foodborne illness is a very real threat, demanding care and continued dedication. According to the WHO, “more than 600 million people fall ill and 420,000 die every year from eating food contaminated with bacteria, viruses, parasites, toxins or chemicals. As for the economic price tag, according to the World Bank, unsafe food costs low-and middle-income economies alone about US$ 95 billion in lost productivity annually.”  

At Nelson-Jameson, we are proud to recognize and celebrate World Food Safety Day. Our main goal is to help our customers produce the safest and best product they can.  Every product, service, and program we offer are all designed to contribute and build up cultures of food safety 365 days a year. We are committed to working with you and the vast array of stakeholders in ensuring a safe food supply…through teamwork we can take on the challenge and together celebrate the continued path towards food safety excellence around the world.
