Nitrofuran Screening Kits

The new line of MaxSignal ELISAs improves
the analysis of nitrofurans in feed, fish, shrimp,
meat, honey, milk, and serum. These kits
combine fast ELISA protocols with high sensitivity
(0.025 ppb or below). Kits include the MaxSignal
Nitrofurantoin (AHD), the MaxSignal Furaltadone
(AMOZ), the MaxSignal Furazolidone (AOZ), and the
MaxSignal Nitrofurazone (SEM). All of these ELISA kits
incorporate a single extraction protocol that can be
used for testing samples for the detection of nitrofuran
antibiotics—users take one sample, perform one
extraction, and test for AHD, SEM, AMOZ, and AOZ.

Gliadin and Sesame Tests
 

 

Gliadin and Sesame Tests

According to Neogen, the new rapid lateral flow tests for gliadin (gluten) and sesame provide results in just five minutes after extraction. The Reveal 3-D for Gliadin R5 test detects as little as 5 ppm of gliadin (10 ppm gluten) on environmental surfaces and in rinses. The test kit is in a sensitive format and conforms to influential Codex Alimentarius guidelines. Reveal 3-D for Sesame also detects as little as 5 ppm of sesame in rinses and on environmental surfaces. Accurate results aid in cleaning validations or verification of existing procedures to prevent cross-contamination of sesame within manufacturing facilities.

Compact, Easy-To-Use Titrators
 

Compact, Easy-To-Use Titrators

EasyPlus is a compact and simple titrator specifically designed for basic requirements and first time users of automatic titrators in the food and chemical industries. Previous models have focused on advanced automation solutions, flexible method structures, and secure networking software. EasyPlus focuses specifically on accurately automating routine titrations. The interface is modeled on the familiar app format. New operators already know and understand this interface style, making familiarization and operation quick and easy. iTitrate guidance leads operators through setup and method programming step-by-step. The ­EasyPlus also features 15 different operating languages. METTLER ­T­OLEDO, 800-638-8537, www.mt.com.


Big Six STEC Controls

Six non-O157 serogroups of Shiga-toxin producing Escherichia coli (STEC) strains have been added to Microbiologics’ line of ready-to-use QC microorganism products. The six new STEC strains are the same six STEC serogroups the USDA and the FSIS recently classified as adulterants in non-intact raw beef. The STEC strains are initially offered in qualitative KWIK-STIK and LYFO DISK formats along with two pre-packaged QC Microorganism Sets; one set includes the Big 6 STEC strains and the other includes Big 6 STEC strains plus serogroup O157. Microbiologics, Inc., 800-599-2847, www.microbiologics.com.


Extraction of Mycotoxins

ISOLUTE Myco SPE columns are used for the “catch and release” cleanup of mycotoxins from food matrices prior to analysis by LC-MS/MS. The ISOLUTE Myco sorbent is a proprietary polymeric phase optimized for the extraction of a broad spectrum of mycotoxins from a wide range of foodstuffs, enabling chemists to utilize a single SPE product to extract all relevant mycotoxins from an individual foodstuff. Using a single, easy-to-use sample preparation product, along with optimized matrix specific application notes, users are able to prepare diverse samples for analysis by LC-MS/MS. The coupling of a dedicated polymer based sorbent with LC-MS/MS analysis also saves time since more samples can be processed each day. Biotage, 704-654-4900, www.biotage.com.


Antimicrobial Cable
 

Antimicrobial Cable

According to the company, the DEFENDER antimicrobial cable jacket eliminates greater than 99 percent of bacteria (e.g. E. coli, Salmonella) and fungus (e.g. Aspergillus) within 24 hours of exposure. The cable contains a silver ion based antimicrobial additive commonly used in many consumer packaged goods. Adding this to the cable jacket during the manufacturing process provides long-term broad-spectrum protection from bacteria, mold, and fungus. Protection is continuous and doesn’t transfer to skin or other surfaces. The bright green jacket allows for easy visual inspection during required check-ups for cleanliness. It’s ideal for wash down areas, canning or bottling process lines, and conveyor systems in the food and beverage industry. TPC Wire & Cable Corp., 888-286-0785, www.tpcwire.com.


Thermogravimetric Analyzer
 

Thermogravimetric Analyzer

The TGA701 Thermogravimetric Analyzer determines weight loss as a function of temperature in a controlled environment. Moisture and ash are determined in various foods, feeds, meats, oilseeds, and pet foods. Complying with AOAC, AACC, and ASTM-approved methodology, the TGA701 replaces traditional analytical techniques that require vacuum ovens, muffle furnaces, or microwave ovens. Sample carousel allows 19 samples to be analyzed simultaneously. LECO Corp., 269-985-5496, www.leco.com.


Testing for T-2 and HT-2

The new AgraQuant ELISA test kit for T2 and HT2-toxin has high cross reactivity between both toxins (>90%). Calibrants used in this test kit are from 25 to 500 ppb sum of T-2 and HT-2 toxin and are therefore in line with the requirements set in the European Commission’s recently published document 2013/165/EU, which recommends maximum levels for the sum of T-2 and HT-2 toxin in various food and feed matrices.

Smart Wireless HACCP
 

Smart Wireless HACCP

The Checkit wireless food safety monitoring solution is a fully-digital and automated system that eliminates the need for paper-based manual checks and time-consuming report generation. Smart wireless sensors ensure 24/7 monitoring of temperature, humidity, and the door status for hot/cold food storage equipment in food service areas, while flexible handheld units collect food temperature and hygiene data at the press of a button to reduce the risk of human error. All data is time-stamped and downloaded to a centralized database, which automatically generates food safety compliance reports along with a full audit trail. It also sends alerts to PCs, tablets, or smartphones if there is a problem. Elektron Technology, 760-343-3650, www.checkit.net.
