Evaluation of lamb meat safety for meat snack production after the use of the feed supplement LaktuVet-1 in animal diets

Overview

Gorbanov and Giro tested lamb muscle tissue from Edilbay-breed sheep after a 90-day feeding trial with the bifidogenic feed supplement LaktuVet-1, then used the tested meat to formulate dried lamb meat snacks. Lead was detected at 0.02 mg/kg in the supplemented group and 0.03 mg/kg in the control group, while cadmium and arsenic were both reported below 0.01 mg/kg in both groups. The article is routeable to lamb/mutton and processed meat snack context, but the auto-fetch filename is a false soy-products/cadmium match.

Key numbers

Table 1 reports toxic-element concentrations in lamb meat muscle tissue:

Metal	Experimental group	Control group	Permissible level cited by paper	Unit
lead (Pb)	0.02	0.03	0.5	mg/kg
cadmium (Cd)	<0.01	<0.01	0.05	mg/kg
arsenic (As)	<0.01	<0.01	0.1	mg/kg

The experimental group’s lead (Pb) concentration was 33.3% lower than the control group’s concentration according to the paper’s narrative. Both groups were below the cited limits for Pb, cadmium (Cd), and arsenic (As). The authors also report that the finished meat-snack microbiological tests found no Salmonella spp., E. coli, Listeria monocytogenes, sulfite-reducing clostridia, or Staphylococcus aureus.

The optimized meat-snack formulation was lamb meat 100 kg, table salt 1800 g, nitrite salt 1000 g at 0.6%, white sugar 200 g, starter cultures 30 g, soy sauce 1000 g, black pepper 100 g, and ascorbic acid 50 g. During salting/marinating, meat pH declined from 6.03 to 5.53.

Methods (brief)

The feeding experiment formed two groups of 20 sheep each. Both groups received a base diet including compound feed concentrate; the experimental group additionally received LaktuVet-1 for 90 days. After slaughter, meat samples were analysed at the Vavilov University UNIL laboratory. Lead and cadmium were measured by atomic absorption spectrometry with flame atomization under GOST 30178-96. Arsenic was measured by atomic absorption spectrometry with hydride generation under GOST R 51766-2001. Active acidity was measured potentiometrically with an AQUASEARCHER TM AB33PH benchtop meter. Meat snacks were dried in a Kitfort KT-1910 dehydrator and assessed under the Customs Union food safety technical regulation TR TS 021/2011.

Implications

This source contributes a small controlled-feeding lamb-meat occurrence point for Pb, Cd, and As, with direct relevance to lamb/mutton raw material and indirect relevance to dried meat snacks. It does not establish market occurrence or seasonal/geographic variance because the design compares one farm/feed intervention rather than sampled retail products. The Cd and As results are censored at <0.01 mg/kg and should be stored as censored values, not zeros.
