We are pleased to announce the publication of our study “Detection and characterization of Clostridium botulinum isolated from powdered infant formula” in Frontiers in Microbiology.

As part of an investigation into a multistate outbreak of infant botulism, IEH laboratories detected and isolated the microorganism from various samples including un-opened powdered infant formula cans. A tiered analytical approach was used combining pre-enrichment and highly sensitive polymerase chain reaction application which allowed for extremely low levels of C. botulinum in the samples to be recovered, isolated and characterized using whole genome sequencing. The findings of this study serve to improve current control measures for C. botulinum in the infant formula industry.

IEH Laboratories & Consulting Group congratulates Dr. Mohammad Koohmaraie on being selected as the recipient of the 2026 R.C. Pollock Award by the American Meat Science Association (AMSA).

Presented in recognition of outstanding contributions to teaching, extension, research, and service, the award honors individuals whose work has made a lasting impact on the meat industry. Dr. Koohmaraie was recognized for his contributions to meat quality, food safety, and industry education.

IEH Analytical Laboratories now offers comprehensive honey testing lab services to support authenticity verification, quality assessment, and regulatory compliance.

Analytical capabilities include physicochemical parameters such as hydroxymethylfurfural (HMF), moisture, and electrical conductivity, along with sugar profiling by HPLC to identify atypical compositions associated with adulteration. Stable isotope ratio analysis is used to detect C3 and C4 sugar addition.

Additional services include multi-residue screening for pesticides, veterinary drugs, and environmental contaminants using LC-MS/MS and GC-MS/MS methods. Microbiological testing is also available as required.

These services support producers, importers, and retailers in addressing increasing regulatory and commercial scrutiny related to honey authenticity and labeling.
