Safety of viable embryonated eggs of the whipworm Trichuris suis as a novel food pursuant to Regulation (EU) 2015/2283

Abstract

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on viable embryonated eggs of the whipworm Trichuris suis as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The applicant proposes to use the NF as a food supplement in the format of a 15-mL bottle containing 250 viable embryonated eggs of T. suis. The target population for the NF is the general population. Considering the compositional data and proposed conditions of use, the consumption of the NF is considered of no nutritional relevance. Available data suggest that most larvae of T. suis after hatching in the intestinal tract of humans remain immature and live for several weeks in the gastrointestinal tract of the human host. Nevertheless, under certain circumstances, T. suis can be invasive in human, being able to mature into adult size and reproduce in humans. Human studies have also shown that administration of T. suis ova may increase the incidence of adverse gastrointestinal reactions. The Panel considers that there are no studies available that demonstrate the safety of this NF intended for the general population at a proposed intake of 250 viable embryonated eggs of T. suis ova per day. Based on the available information, the Panel cannot establish a safe dose at which no safety concerns would be expected. The Panel concludes that the safety of the NF has not been established.
