In order to promote farming of guinea fowl and to diversify the sources of income of Ivorian farmers, a survey was conducted in 2016 in 15 regions (1

Guinea fowl production is very important for some countries from a socioeconomic and nutritional perspective. Guinea fowl production is low in the Iv

The European Commission asked EFSA for an opinion on the safety for the target animals, consumer, user and the environment and on the efficacy of a l‐lysine monohydrochloride (HCl, minimum 98.5%) and of a concentrated liquid l‐lysine (base, minimum 50%) produced by a genetically modified strain of Corynebacterium glutamicum (NRRL B‐50775). They are intended to be used in feed or water for drinking for all animal species and categories. Neither the production strain C. glutamicum NRRL B‐50775 nor its recombinant DNA was detected in the final product. Therefore, the product does not pose any safety concern associated with the genetic modification of the production strain. l‐Lysine HCl and concentrated liquid l‐lysine (base) produced by C. glutamicum NRRL B‐50775 are considered safe for the target species, for the consumer and for the environment. l‐Lysine HCl produced by C. glutamicum NRRL B‐50775 is considered not irritant to skin or eyes and not a skin sensitiser. In the absence of data, the FEEDAP Panel cannot conclude on the potential toxicity by inhalation of l‐lysine HCl produced by C. glutamicum NRRL B‐50775. Concentrated liquid l‐lysine (base) produced by C. glutamicum NRRL B‐50775, due to its high pH (11) it is anticipated to be corrosive to skin and eyes and poses a risk by inhalation. l‐Lysine HCl and concentrated liquid l‐lysine (base) produced by C. glutamicum NRRL B‐50775 are considered as efficacious sources of the essential amino acid l‐lysine for non‐ruminant animal species. For the supplemental l‐lysine to be as efficacious in ruminants as in non‐ruminant species, it would require protection against degradation in the rumen.
