Gorbanov and Giro 2025 — Toxic elements in lamb meat used for meat-snack production

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:

The experimental group’s 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, Cd, and 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.

Verification notes

PDF extracted 2026-05-31 from the auto-fetched queue. The downloaded filename incorrectly identifies the paper as a soy-products cadmium result; the article itself is a Russian lamb meat safety and meat-snack formulation study. Metadata are taken from the bilingual title page: Proceedings of VSUET, 2025, volume 87, issue 1, pages 86-92, DOI 10.20914/2310-1202-2025-1-86-92. Numerical values were transcribed from Table 1 and checked against the English and Russian abstracts. The table reports censored Cd and As as <0.01 mg/kg in both groups; this page preserves the censoring and treats As as total arsenic (tAs) because the paper does not speciate inorganic arsenic. Matrix terms are normalized to the existing broad descriptors meat and processed-meat; lamb-specific and sheep-muscle detail remains in sample_population and body text. No consumer brand contamination data are present; LaktuVet-1, Prestart FB SAZ, AQUASEARCHER, Kitfort, and GOST/TR TS references are feed additive, starter culture, instrument, equipment, and standards/method names used in methods, not consumer brand occurrence findings.
