Consumer Response to Mechanically Tenderized Beef (MTB) and MTB Labels: An Exploratory Focus Group Study.

In May 2016, labeling of certain nonintact mechanically tenderized beef (MTB) products was mandated in the United States. MTB products should be handled differently by the consumer because pathogens can be transferred from the exterior to the interior of the meat during the tenderization process. Without labeling, it is difficult to visually distinguish between some intact beef and MTB products, which is a concern because MTB products require higher internal cooking temperatures for safety.

Detection of ricin contamination in liquid egg by electrochemiluminescence immunosorbent assay.

Unlabelled: A monoclonal antibody-based electrochemical luminescence method was developed for detecting and quantifying ricin in liquid egg, with a limit of detection of 0.2 ng/mL. Because this highly toxic protein, present in the seeds of Ricinus communis (castor), has been used for intentional poisoning in the past, it is important to have sensitive and reliable analytical methodology to detect ricin in food matrices such as liquid egg.
