“…However, the use of plant ingredients can introduce other contaminants such as polyaromatic hydrocarbons (PAH), which can also be present in marine feed sources (Berntssen, Julshamn, et al., ; Berntssen, Olsvik, et al., ; Nácher‐Mestre, Serrano, Portolés, et al., ). Other expected contaminants in plant feed ingredients are mycotoxins and pesticides (Gonçalves, Naehrer, & Santos, ; Matejova, Svobodova, Vakula, Mares, & Modra, ; Nácher‐Mestre et al., , , ). Besides, these specific contaminants, other nontarget (non‐pre‐selected) unknown and/or nonexpected undesirables, can potentially contribute to food safety of farmed fish.…”
