Correction: Taha et al. Assessing Bacterial Viability and Label Accuracy in Human and Poultry Probiotics Sold in the United Kingdom. Microorganisms 2025, 13, 1933

In the original publication [1], there was a mistake in the column “Observed Viable Plate Counts (Mean ± SD)” of Table 2. Details and viable counts of commercial poultry probiotic products and Table 3. Details and viable counts of commercial human probiotic products as published. The SD values were presented in a truncated format and should appear as full SD values. The corrected tables appear below.

Table 2. Details and viable counts of commercial poultry probiotic products.

¹ For products P9 and P12, the manufacturer declared the total CFU per gram of product but did not specify individual CFU counts for each bacterial species. Instead, the label listed each species as a ratio of the total bacterial population. ² Identification of isolates by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry. ³ Mean ± standard deviation per gram. Observed means are based on n = 3 replicates for multi-species products and n = 4 for single-species products.

¹ Per form (capsule or tablet, as specified in the “Form” column, except for P1, where label showed counts per gram). ² For product P1, viability testing was conducted using two sample types: (i) a single tablet, and (ii) a composite of seven tablets equivalent to 1 g, as the label declared viable count per gram. No colony growth was observed in either case on any agar medium. ³ Identification of isolates by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. ⁴ Mean ± standard deviation per form. Observed means are based on n = 3 replicates for multi-species products and n = 4 for single-species products. ⁵ ND = Not declared on label; the manufacturer provided a total count but did not specify counts for individual species.
